A flow transmitter is a device used as a means of measuring the flow of a specific substance, usually a liquid, through a series of conduits 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 pipes 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. The flow transmitter converts the measurements from electrical signals and sends them to a designated receiving agent, such as a computer or automated control station. They are then translated by the flow transmitter to allow control operators to visualize the amount of liquid being transferred through the pipes to regulate the flow and ensure the proper volumes are conveyed 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 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 introduced to each other at a specific and controlled rate. These transmitters can also be useful in underground piping systems, where standpipe water volumes must be monitored for changes in usage and pressure. Whenever a liquid material needs to be transferred from one medium to another through a controlled pipeline process, a flow meter and flow transmitter can be implemented to ensure material is 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 at which the material is being transferred and whether or not the flow rate is within regulations for the specific piping system. Velocity refers to the speed at which the 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 put under by the amount of material being shipped.
