What is a flow meter?
A flow meter is an instrument that indicates the flow rate to be measured and/or the total amount of fluid in a selected time interval. Simply put, it is a meter used to measure the flow of fluid in a pipe or open channel.
A flow meter also called a flow sensor, is a device or an instrument used to measure the linear, nonlinear, mass, or volumetric flow rate of a liquid or a gas.
Here, let’s take a closer look at what is a flow meter.

If you need to know the flow rate in you pipe, or river, that when you need a flow meter. So, flow meter is the instrument that can finish the flow measurement.
Flowmeters consist of a primary device, transducer, and transmitter. The transducer senses the fluid that passes through the primary device.
The transmitter produces a usable flow signal from the raw transducer signal. These components are often combined, so the actual flow meter may be one or more physical devices.
Different types of flow meters are available for different applications, and depending upon the requirement, a careful selection of flow meters is made.
For e.g., we prefer vortex flow meters flow steam flow measuremnet. And we like the ultrasonic flow meters for non-contact pipe flow measuremnt.
Turbine type flow meter cannot be used for measuring the flow in an unclear liquid (wastewater or corrosive liquids).

How to select the right flow meter for your application?
There are no “universal” flow meters which are suitable for all applications.
Selecting the proper technology for your application requires, writing a flow specification which covers the use of the meter.
There are usually trade-offs with each meter type, so knowing the critical specifications will be important.
There are some question that need to be answered before choosing a Flow Sensor.
- What is the fluid being measured?
- Do you require rate measurement and/or totalization?
- If the liquid is not water, what viscosity is the liquid?
- Do you require a local display on the flow meter or do you need an electronic signal output?
- What is the minimum and maximum flowrate?
- What is the minimum and maximum process pressure?
- What is the minimum and maximum process temperature?
- Is the fluid chemically compatible with the flowmeter-wetted parts?
- If this is a process application, what is the size of the pipe?

Magnetic flow meter is also called electromagnetic flow meter, mag flow meter or magmeter. Suitable for the measurement of conductive liquids.
Turbine flow meters are velocity flow meters, also called impeller flow meters. Used to measure the instantaneous flow and cumulative flow of liquids and gases.
Vortex flow meter, also called Vortex shedding flow meter. Vortex Flow Meter is suitable for flow measurement of steam and various liquids and gases.
Precession vortex flowmeter is a new type of gas flowmeter. It can be used for the measurement of natural gas, propane, air, nitrogen and other gases.
The ultrasonic flow meter measures the liquid flow rate quickly and effectively. There are two types of ultrasonic flowmeter technology: Doppler frequency shift and transit time.
Ultrasonic Gas Flow Meter uses the principle of measuring the transit time of ultrasonic waves in the pipeline. Ultrasonic Gas Flow Meter is an ideal choice for various gas measurements.
Differential Pressure Flow Meter is also called DP flow meter. Differential pressure flow meters use the principle of differential pressure to measure the flow of liquid, gas and steam.
Volumetric Flow Meter, as a mechanical flow meter, is also called Positive displacement flowmeter. It can measure the volume flow of high viscosity and corrosive fluids.
