Product Details

The LZD127 mine explosion-proof and intrinsically safe flowmeter is a meter that measures the liquid flow in a circular tube based on the principle of "Faraday's law of electromagnetic induction". The instrument is a high-tech product developed by the company for underground mines and other places containing explosive mixtures such as methane and coal dust. The whole design meets the requirements of GB3836.1-2000, GB3836.2-2000, GB3836.4-2000 electrical equipment for explosive gas environment, and has obtained the safety mark certificate for coal mining products issued by the Safety Standards Center of Mine Products of Anhui Province. Explosion-proof type: mine explosion-proof and intrinsically safe type, explosion-proof mark Exd[ib]I. It is the only electromagnetic flowmeter manufacturer that has obtained this certificate. Reasonable use of lining materials and electrode materials can achieve good corrosion resistance and wear resistance.
