Liquid Flow Meters and Switches

Before we understand the difference between a flow transmitter and a flow meter, let us know their need. Both these devices are used to measure the flow of liquid or gas. Today, in industrial processes, there is a necessity to regulate the flow of fluid or gas. So, the primary purpose of such devices is for process control. Now that we have that cleared up. What is a  flow meter and nozzle ? Flow meters and nozzles are devices used to measure the flow of liquid or gas as they pass through pipes. It is a piece of engineering equipment that measures, monitors, and record the flow rate, discharge, or pressure of liquid and gasses. There are various types of flow meters – differential pressure flow meters, positive displacement flow meters, open channel flow meters, and electromagnetic flow meter. What is a flow transmitter? A flow transmitter is similar to the flow meter with the difference that it has electronics inside the pipe to provide electrical output in...

In industrial work settings, the accurate measure of flow is highly critical. Not only does this define profit or loss, but consumer and worker safety are at stake as well. Flow meters are vital in the precise and accurate measurement of flow rate (mass or volume), i.e. the amount of fluid that passes through a pipe. Flow meters are used in a variety of applications. They measure the mass flow rate or volumetric flow rate. The application will depend on the capacity and type of the flow meter. As a result, each type of flow meter will have its own engineering requirements and constraints. A flow meter will often be referred to by its name. Common examples include flow indicator, flow gauge, liquid meter, etc. This depends upon the industry where it is being used; nevertheless, the function will be the same. There are five essential types of flow meters. Although the list below is by no means exhaustive, it addresses the most well-known types of flow meters used in i...
