What is a velocity flow meter?
Velocity Flow Meter is a flow meter that obtains flow parameters by directly measuring the flow rate of the full pipe in the closed pipe section. The flow rate can be calculated by measuring the velocity of the flow by using a velocity flow meter. Velocity flow meters mainly include-electromagnetic, ultrasonic, turbine, vortex, precessing vortex, rotor, etc.
Flow Meter Types
There are many types of flow meters. Basically, there are the following types of flow meters
Why are there so many types of flow meters? This starts with the working conditions of the factory. The three elements of working conditions, medium, temperature, pressure, and conditions are ever-changing. Create thousands of types of working conditions. It requires different principles and different types of flow meters.

More about Different Types of Flowmeters – Technical and Application Analysis.
Area Velocity Flow Meter
Variable area flow meters are flow meters in which the fluid must pass through a restricted area. Because the flow cross-sectional area of the flow meter varies with the height of the float. Therefore, this type of flowmeter is called variable area flowmeter or equal pressure drop flowmeter. The typical instrument of this type of flowmeter is a rotameter. This is in contrast to flow meters such as orifice plates and venturi tubes, where the area of the flow element remains fixed. Variable area flowmeters can measure of gas and fluid flow.
Variable area flow meter advantages and disadvantages
- The advantages of the variable area flow meter are simple structure and easy testing, suitable for measuring small flow.
- The disadvantage of variable area flow meter is that it is easily affected by factors such as fluid density, pressure, and viscosity. When testing the flue gas flow, because the flue gas contains dust, the area flowmeter cannot be used.

Mechanical Flow Meter
Mechanical flow meters are a type of flow meters that use arrangement moving parts to measure flow. The fluid passes through a series of gears or chambers (positive displacement or PD) or through a rotating turbine or rotor. Mechanical flowmeter is different from electromagnetic and ultrasonic in principle. Mechanical flow meters easily monitor liquid flow rates for water, fuels, viscous fluids and more.
