8750W

The measurement principle of Emerson 8750W electromagnetic flowmeter is based on Faraday's law of electromagnetic induction, which states that when conductive liquid flows through the sensor, it will cut the magnetic field lines and generate an induced electromotive force proportional to the flow rate. Inside the sensor, there is a pair of coils located on both sides. When powered on, they generate a magnetic field perpendicular to the flow direction. Meanwhile, a pair of electrodes perpendicular to the coil are in contact with the liquid and are responsible for detecting the induced voltage generated. Subsequently, the transmitter converts this weak voltage signal into a standard flow reading for display or output to the control system. The entire process has no flow-blocking components. It is combined with an insulating lining to prevent signal short circuits and ensures long-term reliability through designs such as a dual-chamber transmitter housing.

The Rosemount 8750W Magnetic Flow Meter reduces lifecycle costs and unplanned shutdowns by accurately measuring water and wastewater flows in a variety of utility applications. The 8750W is supported by intelligent diagnostics that help users take advantage of improved installation, maintenance and process-management practices. With fully welded sensor construction and an isolated, replaceable terminal block the 8750W is the most dependable meter available for utility and water applications.
