What is a flowmeter?
Flowmeter (flowmeter, flowmeter) is a device that is used to measure the amount of liquid, gas or vapor passing through it. Some flowmeters measure the flow rate in terms of time. For example, 50 liters per minute. Some other types of flowmeters calculate the total value of the passing flow.
Flowmeter (flowmeter, flowmeter) consists of two primary parts: transducer and transmitter. The transducer senses and identifies the flow passing through the flowmeter. The transmitter also produces a usable signal based on the raw signal received from the transducer.

Some flowmeters calculate its value based on the volume of the passing fluid, such as positive displacement flowmeters. The second group calculates its value based on the flow rate of the fluid, which types include magnetic, turbine, ultrasonic, and vortex flowmeters. The third group of flowmeters (flowmeters, flowmeters) are those that measure its value based on the mass of the passing fluid, and Coriolis flowmeters (flowmeters, flowmeters) and thermal or thermal flowmeters are among its types. The fourth group are flowmeters that calculate the flow rate based on parameters other than volume, speed, and mass. Among the types of flowmeters of the fourth group, variable pressure flowmeters (flowmeters, flowmeters) can be mentioned.

Types of flowmeters (flow meter, flowmeter)
Rotameter or variable level flowmeter
Rotameter or variable level flowmeter is actually a narrowing tube and a float. This type of flowmeter (flowmeter, flowmeter) is one of the most widely used flowmeters (flowmeter, flowmeter) for gases and liquids due to its low price, simplicity of design, low pressure drop and ability to be used in different environments.
Spring piston flowmeter
This type of flowmeter has a piston inside a narrowing tube. When there is no fluid, the piston is held steady by a spring. This flowmeter (flowmeter, flowmeter) is mostly used for fluids with low viscosity.
Gas mass flowmeter
The thermal mass flowmeter works with the lowest required parameters such as density, pressure and fluid viscosity. Many of these flowmeters (flowmeters, flowmeters) have internal displays and analog outputs for use in data loggers. The most common use of thermal mass flowmeter is in cases where a leakage test is required or a very accurate flow rate is required.
Ultrasonic flowmeter
This type of flowmeter is used for dirty fluids such as sewage and waste. In this flowmeter (flowmeter, flowmeter), Doppler's law and ultrasonic waves are used to determine the amount of fluid.
Turbine flowmeter
This type of flowmeter (flowmeter, flowmeter) has a very high accuracy and can be used to determine the amount of fluids with high viscosity. Turbine flowmeter can only be used in straight pipelines.
Pedal current sensor
This type of flow sensor is widely used for water and similar fluids due to its low price and high efficiency. The pedal flow sensor can only be used in straight pipelines.
Positive displacement flowmeter
When the pipeline is not straight and a turbine meter or pedal sensor cannot be used, a positive displacement flowmeter can be used. Also, this type of flowmeter (flowmeter, flowmeter) can be used for liquids with high viscosity.
Vortex flowmeter
The most important feature of this type of flowmeter (flowmeter, flowmeter) is low sensitivity to flow changes and high resistance to corrosion and fatigue. Also, its maintenance costs are low.
Pitot tube or variable space sensor
Pitot tube has many advantages, including low installation cost, very low pressure drop, low maintenance cost and long service life.
Magnetic flowmeter
This type of flowmeter (flowmeter, flowmeter) is very suitable for conductive fluids. This type of flowmeter (flowmeter, flowmeter) does not have any moving parts, and for this reason, it is very suitable for sewage or dirty and thick fluids.
Anemometer or fluid velocity meter
This flowmeter model is used to determine the amount of air flow. Anmotor, like a magnetic flowmeter, has no moving parts. Of course, vane anemometer is another type of anemometer that has a moving part. Also, anemometers may also have the feature of calculating temperature and humidity.
3 important points regarding the flowmeter
1. There is no "universal" flowmeter that is suitable for all fluids. Choosing the right flowmeter for your needs requires writing down the characteristics of the flow to be measured.
2. Regarding the functioning of the flowmeter, it can be said that different methods are used to measure the amount of flow.
In this sense, the types of flowmeters are divided into several groups:
The first group calculates the amount of passing fluid based on volume, which is also called volumetric flowmeter. The second group is based on the velocity of the fluid passing, the third group is based on the mass of the passing fluid, and the fourth group is based on parameters such as temperature and...
3. The flowmeter consists of two primary parts: the transducer and the transmitter.
Flowmeter technical specifications
One of the features of the flowmeter in general is that it is compatible with all types of systems and fluids. This feature makes it possible to install a flowmeter for any need or location.
Among the other characteristics of flowmeters, it can be said that while flowmeters are a general concept, each of its types has major differences from the other, and one characteristic cannot be attributed to all of them.
The importance of using a flowmeter becomes clear when we know that other traditional methods for measuring the flow rate of fluids are obsolete and the use of a flowmeter greatly increases the level of efficiency and safety of the system.
One of the important factors when buying a flowmeter is that you can basically answer the specialized questions of the seller. For this, an engineer or a device operator are suitable choices.
A water flowmeter generally refers to a flowmeter capable of measuring the amount of water passing through a pipe.
Its types include ultrasonic flowmeter, vortex flowmeter and magnetic flowmeter.
Steam flowmeter also refers to those types of flowmeters that are suitable for measuring the amount of steam or gas, such as: electromagnetic flowmeter, ultrasonic flowmeter, vortex flowmeter, turbine flowmeter, etc.
A digital flowmeter is a flowmeter that uses digital tools to update information in real time and send it to the monitoring system.
Buying and selling flowmeters requires attention to various parameters. Considering the price of the flowmeter and its intended use, it is not possible to make a simple choice, which means that because we need a flowmeter, we need to buy a type of it.
The price of the flowmeter and how to choose the flowmeter depends on the following factors:
Life span, technology used in the flowmeter, material of the body, amount of investment, accuracy of the flowmeter, maintenance cost, location and fluid used, etc.
