Product Details
LDC11Y Pipeline Electromagnetic Flowmeter is a velocity flow meter, which is the product of the combination of fluid mechanics and electromagnetics. It consists of two parts: a flow sensor and a converter. The upper and lower parts of the measuring tube are equipped with an excitation coil, and the magnetic field generated after passing through the excitation current passes through the measuring tube, and a pair of signal electrodes are installed on the inner wall of the measuring tube to contact with the liquid, generating an induced electric potential, and the flow signal is transmitted to the converter, which is converted into a standard signal for output after the converter. It has the advantages of high precision, high stability, anti-interference, and maintenance-free.
