What is a Flow Meter?

Flow Meter Definition

A flow meter is defined as a device that measures the flow rate of solids, liquids, or gases.

Types of Flow Meters

The main types of flow meters include positive displacement, mass, differential pressure, velocity, optical, and open channel flow meters.

Positive Displacement Flow Meters

These meters measure fluid flow by trapping fluid in a chamber and are robust against turbulence.

Mass Flow Meters

These meters measure the mass of the fluid flowing through them, crucial for chemical industries.

Velocity Flow Meters

These meters estimate flow rate by measuring the fluid’s velocity, often using methods like turbine or ultrasonic sensors.
