Anhui Tiankang Group TK1000 series electromagnetic flowmeter

Anhui Tiankang Group TK1000 series electromagnetic flowmeter,Faraday's law of induction (which refers to the induced electric potential generated inside the conductor when it passes through a magnetic field) is the basic principle of electromagnetic flowmeter measurement. This measurement principle can be applied to conductive fluids flowing into a pipe with a magnetic field perpendicular to the direction of the fluid. The electric potential induced in the fluid can be measured using two symmetrically arranged electrodes. The signal voltage UE is proportional to the magnetic induction intensity B, the electrode spacing D and the average fluid velocity v. Since the magnetic induction intensity B and the electrode distance D are constant, the signal voltage UE is proportional to the average flow velocity v. The equation used to calculate the volumetric flow rate states that the signal voltage UE is linearly proportional to the volumetric flow rate. The induced signal voltage is converted into graduated, analog and digital output signals in the converter.

Anhui Tiankang Group TK1000 series electromagnetic flowmeter selection of lining materials should be based on the corrosiveness, abrasiveness, and temperature of the measured medium. Hard and soft rubber are generally used. Hard rubber has a corrosion resistance of up to 65°C, while soft rubber is corrosion-resistant. Polytetrafluoroethylene (PTFE) is excellent in heat and chemical resistance, and PFA has similar properties to PTFE but with better mechanical strength. Polyolefin (PO) is also used for specific applications.
