The LCZ-803 Mine Flameproof and Intrinsically Safe Ultrasonic Flow Meter is a meter that measures the flow of liquid in a circular tube based on the principle of “speed difference method”. It adopts advanced multi-pulse technology, signal digital processing technology and error correction technology to make the flow meter more adaptable to the industrial scene environment, and the measurement is more convenient, economical and accurate. The products have reached the advanced level at home and abroad, and can be installed in coal mines and industrial and mining enterprises with explosion-proof requirements. It has obtained the safety mark certificate for coal mining products issued by the Safety Standards Center of Mine Products of Anhui Province.
The explosion-proof converter is operated by a magnetic induction keyboard, and the operation of the meter can be realized without opening the chassis. Explosion-proof sensors are available in both clip-on and plug-in versions. The inserted sensor has no dripping, can be installed without pressure, has high precision, is maintenance-free, and is more reliable. The external clip sensor is bundled on the outside of the pipeline, does not affect the liquid flow state, and does not need to stop water for installation and maintenance. It is suitable for any pressure pipeline.
