Flow Transmitters
Flow transmitters are used in the oil and gas industry, as well as in water treatment and chemical processing, to measure the volumetric or mass flow rate of liquids or gases through a pipeline or process. These devices work in conjunction with flow meters to provide real-time data on a system's flow rate. The transmitters take the flow measurements and convert them into an electrical signal. This signal can then be used for control, display, or further processing as part of the monitoring system, which is vital for many applications in these industries where precise control and measurement of flow rate are necessary.
Common direct pressure flow meters, as well as mass and ultrasonic flow meters, can be used with flow transmitters to monitor flow in real time. These devices measure one of three things to determine the flow rate: pressure drop, fluid velocity, or sound waves. These are called "primary elements," and they are often used with differential pressure transmitters to make sure the measurement is accurate.
