Flow measurement is the quantification of bulk fluid movement. Flow can be measured using devices called flowmeters in various ways. Volumetric flow meters quantity volumetric flow rate while mass flo
A positive displacement flowmeter of the oval gear type. Fluid forces the meshed gears to rotate; each rotation corresponds to a fixed volume of fluid. Counting the revolutions totalizes volume, and the rate is proportional to flow.
The paddle wheel assembly generates a flow reading from the fluid flowing through the pipe instigating the spinning of the paddlewheel. Magnets in the paddle spin past the sensor. The electrical pulses produced are proportional to the rate of flow.

A magnetic flow meter is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field. A magnetic field is applied to the metering tube, which re

…When choosing a meter for an application that requires particulate flowing through the pipe, it is best to use a meter without moving parts such as a Magnetic flowmeters. Fire meters are a specialized type of turbine meter with approvals for the high flow rates required in fire protection systems. They are often approved…
