WGCB Gas Drainage Pipeline Parameter Measuring Instrument

The WGCB Gas Drainage Pipeline Parameter Measuring Instrument is a portable intrinsically safe intelligent mining measurement device. When used with an orifice plate, averaging pitot tube, or pitot tube, it can measure the differential pressure, drainage negative pressure, gas concentration, pipeline temperature, mixed flow rate of drainage gas, and pure gas flow rate at various measurement points in the gas drainage pipeline.
Performance Characteristics of the WGCB Gas Drainage Pipeline Parameter Measuring Instrument
The WGCB Gas Drainage Pipeline Parameter Measuring Instrument features strong functionality, light weight, simple operation, and fast measurement. The instrument also includes automatic data protection in case of power failure and automatic power shutdown when the battery is low. It can measure data from 128 measurement points, and all measured data can be stored, displayed, and printed.
