Flow Meters & Transmitters

Flow meters and transmitters are crucial instruments used in a wide variety of applications to measure the flow of fluid, which can be a liquid or gas. They can be categorized into many types, including volumetric flow meters, differential pressure flow meters, and Venturi flow meters, each with their specific use cases and measurement techniques.

Flow transmitters take the measurements from the flow meters and convert them into a signal that can be read by control devices. This signal can be transmitted to a remote location for monitoring and control, making a flow transmitter especially useful in situations where the flow meter is located in a difficult-to-reach or hazardous location.

The integrated electronic circuit in these devices helps to ensure accurate and reliable readings. Some systems may also have multiple tubes for different flow measurements or for redundancy to ensure the accuracy and reliability of measurements.
