Can Anybody Tell Me About The Velocity And Displacement Devices For Flow Measurement?
Velocity flow measurement devices are based on the velocity of a fluid to determine its flow rate. There are many devices that are based on the velocity to measure flow rate but the most popular device is magnetic flow meter. These devices are being designed in such a way that for plant transmission these devices can produce an ideal electrical signal. Magnetic flow meter devices are based on the Faraday’s law. According to the Faraday’s Law an amount of voltage produced by a conducting fluid is directly proportional to the velocity of the fluid when passed through a magnetic field. These devices are constructed in such a way that a non conducting material is being aligned with a pipe. With the non-conducting wall two electrodes are also mounted. Magnetic flow meters are not suitable for Hydrocarbon’s due to their low conductivities. Similarly these are a number of flow measurement devices based on displacement but the most commonly used one is Turbine Meter. A rotator that is magnetic
