Mining Intrinsic Safety Flowmeter

LZD280/100G Mining Intrinsic Safety Flowmeter

Product Introduction
LZD280/100G Intrinsically Safe Mine Flowmeter is a battery powered electromagnetic flow meter with an explosion-proof label of Ex ib I Mb. This type of flowmeter uses the Faraday's law of induction. When the conductor moves through the magnetic field to cut the magnetic induction line, the two ends of the conductor will generate an induced electromotive force. The magnitude of the induced electromotive force is a function of the flow rate. By measuring induced electromotive force and processing data, accurate fluid flow rate can be obtained.
This type of flowmeter can measure various corrosive, non corrosive liquids, heavy turbidity coal slurry or mud bodies, and is widely used in explosion-proof situations such as underground coal mines, especially in situations where on-site power is not convenient.
