FLOW METERS

A flow meter is a device used to measure the volume or mass of a gas or liquid. Flow meters
are referred to by many names, such as flow gauge, flow indicator, liquid meter, flow rate
sensor, etc. depending on the particular industry.
Types:

•  Mechanical Flow Meter

a. Turbine Type: Turbine meters are dry register mechanical totalizers that offer
accurate, economical reading of high flows with low pressure loss. The horizontal-axis
turbine drives a vertical shaft, which is magnetically coupled to the sealed register. In addition
to mechanical flow totalizing, registers can be equipped with magnetic pulse reed sensors
well suited for remote totalizing, pacing of electronic metering pumps, and water treatment
applications.
