New large-diameter coal mine gas drainage and gas power flow meter put into use

      The KGW-4 pipeline gas multi-parameter measuring device is a flow meter device specially designed for on-line monitoring of gas concentration, mixed gas flow, pressure and temperature in mine gas drainage pipelines, and has high measurement accuracy. Convenient to use, can be used for continuous detection of gas drainage when the hazard parameters comprehensive parameters. To provide reliable monitoring data for assessing the effect of coal mine gas pumping in and preventing the occurrence of coal mine gas outbursts and explosions, the product's explosion protection type is intrinsically safe for mine use (Explosion proof mark: Exia I Ma).

The KGW-4 pipeline gas multi-parameter measuring device is mainly composed of a multi-parameter flow sensor, a gas concentration sensor and an intelligent flow totalizer (with pressure and temperature compensation). Plug-in installation is generally adopted, and the above-mentioned integrators and sensors can also be centrally installed on a dedicated pipeline in accordance with user requirements to form an integrated structure that can monitor parameters such as pressure, temperature, gas concentration, and flow rate of pipeline gas. It can display the instantaneous gas flow under the conditions of pipeline gas pressure, temperature, gas concentration, standard conditions and working conditions, cumulative flow under standard conditions, pure gas flow, etc., as well as output standard frequency signal and 485 communication output.
