1# What is an instrument?
You have probably heard the word instrumentation,
but what do we really mean by instrumentation?
At first glance, we can say that precision tools mean tools + precision (tools plus precision), that is, tools that work accurately.
So, assuming this definition, what does it mean to work accurately?
If you are new to this profession, you have probably answered this question yourself
We mean accuracy, that is accurate measurement with the least error.
Therefore, the exact tool, art and science is the use of equipment that measures the desired quantities in the factory or site well and with the least error.
The quantities being measured may be the surface of a tank or flow passing through a pipe, or the temperature of a furnace, or the pressure associated with a tank or pipe.
History of instrument science
before 2006, the field of instrumentation was generally considered a subset of the field of electricity, and the electrical engineer also performed the duties of instrumentation engineer.
But then, due to the development of precision instruments and the connection of industries with a large set of equipment and sensors,
it was decided to consider this field as a separate branch of industry.
Engineers in this field are known as instrumentation and control engineers.
The steps for implementing an instrument project are summarized as follows:
The first step is to understand the process we intend to control.
Designing a process is highly specialized and tailored to the intended industry and goal.
At the beginning, a process or chemical engineer and a safety engineer analyze the process to be performed in the system.
Then, in accordance with the initial information and the process that is given to us, the instrumentation and control unit starts designing the control system and identifying the required instrumentation equipment
For this purpose, maps such as P&ID map will be delivered to you.
The second step is to choose the right equipment, which is your key specialty and task, and you will master it by gaining skills in this field
Installation of equipment
After supplying and purchasing the equipment, the process of installing and connecting the equipment will begin
Therefore, you should be familiar with the installation and connection of all equipment on the line and tanks
Also, documents such as hook-up documents are prepared by you and will be provided to officials and employers
In this document, appropriate and comprehensive information about installation and connections is mentioned
Commissioning and operation
The last step is to set up and operate the process
Undoubtedly, the most stressful stage is this stage
You must consider the necessary safety when starting the process and pay attention to the fact that the first issue in design and installation is safety
2# Instrumentation standards
At the beginning of any work, we must get acquainted with the rules and principles governing that work (job).
In instrumentation, we also have a set of principles and rules, which we call instrumentation standards.
These standards are the basis and guide of the instrument for the relevant organizations to do all the work in this field.
All the do’s and don’ts for designing, building and installing any equipment are called standards.
Instrumentation standards may be international or domestic.
International API and ISA standards are also among the most widely used instrumentation standards.
An instrumentation engineer should be well acquainted with these standards, and according to some professors, these standards should be maintained.
Standard equipment installation
equipment installation standard is also included in the standards text.
This means that if you are looking for a standard for installing an equipment, read the original text for the standard for that type of equipment; One of its clauses is related to equipment installation
3# Instrumentation equipment
The most basic instrumentation equipment is flowmeter, level gauge, thermometer and pressure gauge
In defining the instrument (step 1), we said that our goal of the instrument is to measure the flow (flowmeter), surface (level gauge), temperature (thermometer) and pressure (barometer) quantities with the least possible error
These are the first equipment that you, as an instrumentation engineer, should be familiar with
You need to be familiar with their features and be able to choose the best equipment for your process
Other equipment that you should be familiar with is industrial valves
Splitter box, cable and gland are other equipment that you will have a lot of trouble with and you should get acquainted with their types
Ability and skill in choosing and buying the right equipment requires experience and enduring the hardships of the road.
It is recommended that the first 1 to 2 years with a focus on knowledge and learning equipment, pay and then work closely with the equipment work.
at the end, experience and repetition and presence in a number of projects to dominate in these areas will lose Found.
Remember that in today’s world you have to update your information from time to time and do not lag behind the world.
Purchased and supplied instrumentation equipment
In the following, together with the instrumentation guide, we will give a brief review about the top brands and companies that supply instrumentation equipment.
Today, with the spread of science and knowledge, instrument stores and companies supplying instrumentation tools have a growing trend, and you can easily meet your needs to buy this equipment
The following is a list of the top companies supplying instrumentation equipment:

The rtd task is to measure the temperature with high accuracy
The pressure and temperature measuring products of these two companies are of good quality
The following companies can also be mentioned as other reputable manufacturers of instrumentation equipment
Another widely used and very important equipment in various industries are flowmeters (to measure the flow through the pipe)
Undoubtedly, the KRONHE brand is one of the best manufacturers of this product
These companies are considered as instrumentation guide in purchasing and supplying instrumentation equipment
4# Industries related to instrumentation
When it comes to an industrial environment and doing an industrial project, it is almost impossible to imagine that project to be done without instrumentation equipment and a precision instrument engineer.
In fact, in various industries, precision instruments are used as a solution to better advance the process and achieve the best results.
Instruments in the oil and gas and petrochemical industries
Many industries use a variety of fluids, including water, oil, gas, and petrochemicals, and these fluids are transported from place to place through process lines and pipes
Large and small tanks are also used for storage
In these industries, of course, it is necessary to measure the amount of fluid passing through and even the amount of fluid stored
using a set of equipment (which is the same as instrumentation equipment)
For example, suppose that an oil refinery, a tube containing a gas that is out of the refineries and sell gasoline output to an external company we are, as you can see, effluent us gasoline
Well, the and your business is money and income (about millions of euros), it is enough that the sensor that measures the gasoline output (called the flowmeter) has a small error
This small mistake can waste your money and sell a lot of your gasoline for free
Earlier in the instrumentation guide, we briefly introduced the measuring instruments and equipment in instrumentation engineering
Many of these equipment are used in oil, gas and petrochemical industries
For example, we will use a flowmeter to measure gasoline output
We will also use level gauges to measure the level of storage tanks
Therefore, in the oil, gas and petrochemical industries, we will use several flowmeters and level meters
We also need a number of barometers and thermometers
Instruments in the cement and mining industries
Instruments are used in the cement and mining industries in the following cases
Measuring the surface of cement silos and minerals by surface transmitters
Measuring the surface of boilers using level gauges
Measuring the pressure on furnaces and boilers
Controlling the discharge of steam from the boilers accurately through appropriate flowmeters
Measuring fuel consumption with flowmeter
Measuring furnace temperature with temperature sensor
The scope of application of instrumentation is very wide and with the introduction of instrumentation, significant progress has been made in production and productivity.
5# Field of instrumentation and academic orientations of instrumentation
If you are one of those people who are curious about the academic education of the instrumentation industry, do not miss the fifth step in the instrumentation guide
Academic and university education in the field of is usually in one of the following ways
If you are a friend who is studying in technical and professional
after going through high school and participating in the associate degree entrance exam, you should choose the associate degree of instrumentation
This trend is offered in most technical universities in 4 or 5 semesters
In some cases, you may have heard of this trend called “Discontinuous Bachelor of Engineering in Control Technology and Instrumentation”
which have similar courses, except that the courses related to instrumentation are more practical and research, and
in it up to As much as possible, the instrumentation equipment is covered
If you are a friend who has studied (or is studying) engineering and math, you have
2 choices in choosing a master’s degree
One of these choices is the master’s degree in instrumentation engineering and automation in the oil industry, the
coefficients of the courses in the master’s entrance exam based on the exam booklet of 1997 are as follows
6# Instrument training
Instruments are taught in various institutions and schools
You also need to research and find the best schools and learn with reputable professors how to work with instrumentation equipment
Practical Instrument Course
One of the most basic courses that an instrumentation engineer can take is
the Theory and Instrument Design course
This course is held in two levels of basic instrumentation and advanced instrumentation, which in general, methods of measuring pressure, level, temperature and flow are taught along with various types of cables and glands and general cases
Engineering degree preparation course is definitely the most important and basic course that you should participate in
Of course, the skill of filling engineering degrees is not obtained with just a few training courses and requires experience and several years of digging in this field
Therefore, make a lot of effort in this field and try to learn this skill from reputable schools and institutes and expert professors in this field
Another course that an instrumentation engineer must complete is the
course of industrial valves and their sizing
Also, due to the proximity of control engineering and instrumentation engineering, a precision instrument engineer must also take control and PLC courses
Because control engineering and instrumentation are inseparable
Working with software such as plc, wincc are among these skills
The F&G Systems course is another course that is recommended to have in hand
Instrument video tutorial
Today, with the development of science and technology, suitable films and videos have been produced for teaching instrumentation
Also, INSTRUMENTATION training package can be used anywhere, and
all our efforts are to provide the necessary skills in this profession
to all our friends in the farthest parts of the country with video quality trainings, and you can as Instrument guide Refer to this package at any time
This package covers all topics related to instrumentation courses
If you are a person who is accustomed to self-study and the use of textbooks, be sure to read the book Liii (Lessons in Industrial Instrumentation)
Map reading and filling in instrumentation engineering documents
At the beginning of this article, we mentioned 4 steps to do a tool project. The first step was to design according to the basic information that was given to us about the system, we started working
One of the most important things we need to do in the design phase is to read the map and fill out the engineering documents
One of the most important documents they give us in this regard is the Instrument list document, which includes a complete list of all the instrumentation equipment used in that project
Of course, if you have new equipment that fits the process, include it in the shopping list and in the datasheet
There is a map for each refinery and each system that shows the equipment used in the system and the processes running in the factory
This map is called the P&ID map. The P&ID map is our guide to refineries and industrial systems
P&ID mapping is the most basic and essential knowledge that an instrumental engineer must master
You will be able to follow the running processes on the site by learning P&ID instrumentation
In fact, it can be said that P&ID maps are the guide tool of any system or Plant
For example, in the pictures below, we have placed a part of the pressure gauge before and after filling
One of your most important tasks as an instrumentation engineer is to fill out instrumentation documents and datasheets
You may be wondering how they prepare P&ID maps
Or what software is used in the instrumentation category and which one should we learn To find out more, follow us on the instrumentation guide?
Valve sizing software
In the field of instrumentation, there are various software, including valves (control valves) and safety field
In fact, sizing valves has its own software and based on this software, we will provide documents about sizing valves
Fisher Control Valve Sizing software is one of these software
Valvestar software is also used for safety valves
Orifice is another instrumentation equipment that is widely used in various industries and projects
We also have sizing for orifices, and one of the most important software used for this is Daniel Orifice Calculator
You can teach and learn these softwares by searching for them
We will also teach all of these softwares in the INS package so that if someone has a learning disability, they can easily acquire this skill
Other software that is recommended in this field to be sure to learn, we can mention AutoCAD that many P&ID and hook-up maps are designed with the same software. Eplan is used for the same purpose
Intools software is another application and suitable for designing our P&ID and hook-up maps
PDMS software is used to design and model industrial units
In the following, and in the instrumentation guide, we will examine the attractive part of the instrumentation labor market
Our goal in the instrumentation guide is to show you the right way to reach the pinnacle of instrumentation and to bring you to the right knowledge and job in the field of instrumentation
7# Instrument engineering labor market
Since the instrumentation field is an almost emerging branch
It has a relatively good labor market and employment (even despite the current state of the country’s industry)
With the start of any industrial project, a number of instrumentation and control engineers are needed to design the system used and the sensors and instrumentation equipment required
Then buy the best equipment and mount it on the planet according to the system
Hiring an instrumentation control engineer
Many companies, including consulting firms, contractors, supervisors, and even sales centers and suppliers, need an instrumentation engineer
Definitely, in order to be hired for a good job with a good salary, you need to improve your technical knowledge
It is recommended that you take the time to train and learn most of the equipment used in the industry and the instrumentation, then start from a factory and industrial environment and try to get in touch with the equipment in person
You will face many difficulties in the beginning (about 3 to 4 years)
But after that you will go much easier
You should also know that the role of instrumentation engineer is a well-established role in the industry
Instrument job and working conditions
In the field of instrumentation, we are faced with a series of sensors
which we are responsible for designing and purchasing
This means that you, as an instrumentation specialist, must purchase, repair, or analyze equipment that samples the amount of fluid in pipes and tanks and sends accurate information about process conditions to the control system
You are dealing with various technical documents and datasheets that we mentioned earlier
one of the most important things that you need to master is filling out engineering documents
Working conditions in this profession also have their ups and downs
most industrial projects are done a short distance from the urban environment and perhaps the only difficulty in this field is far away
at the end, thank you for reading the instrumentation guide to the end, and we hope that by reading the instrumentation guide and paying attention to what was mentioned in it, you will be able to enter this field with a correct look and learn the instrumentation and this lovely job
