CGWZ-100 (A) Comprehensive parameter measuring instrument for pipeline methane gas

Product introduction

CGWZ-100 (A) comprehensive parameter measuring instrument for pipeline methane gas is specially used for online monitoring of methane parameters of concentration, flow, pressure and temperature in coal mine methane drainage pipeline, to provide reliable monitoring data for the evaluation of coal mine methane pumping effect and the prevention of malignant accident occurrence such as coal mine methane outburst and explosion.

Performance characteristics

The instrument adopts the cyclic auto-excitation flow detection technology with a wide range, low measuring prescribed minimum and high measuring accuracy even the flow rate is low to 1m/s.

The flow meter will not generate resistance which overcomes weaknesses of great pressure loss, inconvenience installation and calibration of the vortex precession flowmeter and V-cone flowmeter.

The flow meter can be calibrated in the wind tunnel to facilitate detection problems timely.

The instrument adopts the plug-in installation method and can be installed by opening a small hole in the drainage piple.

Large screen and multi parameters displaying simultaneously make it easier to view the data.。
