What is a Flow Meter?


A flow meter measures both conductive and non-conductive fluids, as well as gases and can be used to totalize or monitor the rate at which media is flowing through a given space.

Flow meters can also be referred to as flow sensors, flow gauges, flow indicators and flow switches. The difference between a flow meter and a flow switch is that at preset rates, flow switches will initiate alarm actuation or automatic system shutdown.


Flow meter types 

They are various types of flow meters. Piston type flow meters are designed for low flow rates in gases and liquids. Shuttle models are used with high flow rates. Paddle models are for larger line sizes. Thermal dispersion technologies feature no moving parts and electronic flow switches include electronics and positive visual indication.
