What is a flow transmitter?

A flow transmitter is a device used as a means of measuring the flow of a specific substance, usually liquid, through a series of ducts or tubes.

A flow transmitter is a device used as a means of measuring the flow of a specific substance, usually liquid, through a series of ducts or tubes. These measurements start as electrical signals, measuring anything from the volume of substance being pushed through the pipe to the speed at which the fluid is moving. Measurements are converted from electrical signals by the flow transmitter and sent to a designated receiving agent, such as a computer or an automated control station. They are then translated by the flow transmitter to allow control operators to visualize the amount of liquid being transferred through pipelines to regulate the flow and ensure the proper volumes are carried at all times.

There are many different applications where a flow transmitter may be required, especially in cases where a flow meter is installed in a series of pipelines, but the meter is not clearly accessible to the operator. A flow transmitter can be installed in conjunction with the flow meter to transmit the results that the flow meter produces to the operator operated control station. This allows the operator to ensure that the correct amount of volume, flow rate, temperature and pressure of the material being transferred through the pipeline is maintained.

These applications can be used in laboratories where specific materials must be presented to each other at a controlled and specific rate. These transmitters can also be useful in underground pipeline systems, where volumes of water to public fountains must be monitored for usage and pressure changes. Whenever a liquid material needs to be transferred from one medium to another through a controlled piping process, a flow meter and flow transmitter can be implemented to ensure the material is being transferred effectively and in the correct amounts.

There are three basic types of flow transmitters that can be used at any point in a transfer process. They are called volumetric, mass, and velocity. Volumetric information allows the operator to determine the amount of volume to which material is being transferred and whether or not the flow volume is within regulations for the specific piping system. Velocity refers to the speed at which material moves through the piping system. Mass refers to the amount of mass that the material being transferred creates as it is sent through the piping system, allowing the operator to control the stress that the piping system can be subjected to by the amount of material being sent.
