CGWZ-100（C）Pipeline Laser Gas Comprehensive Parameter Tester
Product description
CGWZ-100 (C) Pipeline Laser Gas Comprehensive Parameter Tester is an instrument developed for coal mine gas drainage standard evaluation, which is used for on-line monitoring of gas drainage parameters such as flow, concentration, temperature and pressure in gas drainage pipelines.
Features
◎ Based on the principle of laser measurement, methane sensor is free of interference from water vapor, ethane and other impurity gases. It is accurate and stable, and the calibration period is more than 12 months.
◎ It uses the circulating self-excited flow detection technology, with wide range and lower limit of measurement, and can accurately measure parameters even at a flow rate as low as 1m/s.
◎ he tester adopts a plug-in installation structure without any resistance. One instrument is suitable for a variety of pipe sizes and can be tested in a wind tunnel.
◎ he tester can simultaneously display the instantaneous quantity of flow, concentration, temperature and pressure in a single screen, and can also display the accumulative quantity of mixed quantity and single quantity in a certain period of time.
◎ he tester has the function of measuring the ambient atmospheric pressure, and can accurately change the absolute pressure and negative pressure without manual setting.
◎ A single flowmeter simultaneously measures pipeline gas flow, negative pressure and temperature parameters, and has the function of measuring and outputting the standard condition and working condition.
Technical parameters
◎ Flow: (0.0~100.0) m3/min(±1.5%FS)
◎ Methane: (0.0~ 100.0) %, ( 0.00~1.00) % CH4 not more than ±0.04%CH4, (1.00~100.0) % CH4 not more than ±4.0% of the truth value
◎ Absolute pressure: (10.0 ~ 200.0) kPa, not more than 0.75% FS
◎ Temperature: (-10.0~60.0) C (±1.0°C )
◎ Carbon monoxide (optional): (0~100) * 10-6：±4 * 10-6，( >100~500) * 10-6 : 5% of the measured value
◎ Power supply: 9V DC ~ 24V DC, intrinsically safe power supply
◎Explosion-proof type: mining intrinsically safe
