A flow meter (or a flow sensor) is type of flow instrument that is used to indicate the amount of liquid, gas, or vapor moving through a pipe or conduit by measuring linear, non-linear, mass, or volumetric flow rates. The measuring principle of electromagnetic flowmeters is based on Faraday’s law: the voltage induced by a conductive liquid moving through a magnetic field is directly proportional to the speed of the conductive liquid. The induced voltage is measured across two diametrically opposed electrodes.0
A flow meter is meant to measure the amount of gas, steam, or liquid passing around or through it. Although there are many kinds of flow meter sensors that work in different ways, they all have one set goal, and that is to give the most accurate flow rate report based on the application. Types of Flow Meters. There are two categories of flow meters: gas and fluid or liquid. Fluid flow meters have five subcategories: differential pressure, velocity, positive displacement, mass flow, and open channel.
Water flow meters are used to measure the volume of water used in commercial and residential buildings. The water is supplied to homes and offices via a public water supply system. Water meters may also be used at water sources or throughout the water system to calculate the flow rate of a part of the system.
