A flow meter is a device that measures the flow rate of a fluid. They measure the linear, nonlinear, mass, or volumetric flow of a gas or a liquid. Flow meters are known as flow gauges and flow measurement instruments.
For a comprehensive understanding of this topic, I recommend this textbook- Flow Measurements Handbook by ROGER C BAKER 👉[ Ссылка ]

There are two broad types of flow meters widely used in industries;
1. Volumetric flow meters 2. Mass flow meters.
A volumetric flow meter measures the fluid volume passing through a specific location in a set period.
various types of volumetric flow rates available are;
- Differential head type ( orifice plate, venturi meters, annular, rotameter, etc)
- Electromagnetic flow meters
- Ultrasonic flow meters
- Turbine flow meters
- Vortex flow meters
- Positive displacement meters.
Mass flow meters measure the mass flow rate that travels through a tube per unit of time. There are two types of mass flow meters;
- Coriolis Mass flow meter
- Thermal mass flow meter.
A brief description of these various types of flow meters, advantages, and disadvantages. Also, the general application of flow meters was discussed in the video.
