Product introduction

CJZ4Z borehole manifold gas comprehensive parameter tester adopts new flow detection technology, which comprehensively solves the technical problems of borehole gas monitoring. It is the first choice equipment for the evaluation of borehole gas drainage effect. It can monitor methane in boreholes and manifolds in real time Concentration, flow rate, pipeline pressure, pipeline gas temperature and other parameters.

Product Features

   Direct plug-in measurement, no flange, no need to cut off the pipeline!

/min也能准确测量。 There are no blocking and rotating parts in the measuring cavity, and there is no resistance. Even if the drilling gas flow rate is as low as 0.003m3 / min, it can accurately measure.

It is not affected by dust and water vapor, and the measurement is accurate.

Equipped with working mode and standard mode setting function, can set the instrument output mode.

Instantaneous mixed flow, instantaneous pure flow, methane concentration, negative pressure, temperature, total quantity, pure total quantity, daily cumulative quantity, daily cumulative pure quantity, pipe diameter, gas flow direction, date, time, working condition percentage, etc. Display function and upload data to the monitoring system.
