Product Description 
 Type CWC3 portable gas drainage multi-parameter analyzer is designed and manufactured according to the MT / T 642-1996 pipeline gas drainage parameter determination of the relevant provisions of the instrument conditions and GB 3836-2000. CWC3 type portable gas drainage multi-parameter analyzer using methane sensor, pressure sensor and comes with vortex flow sensors were used to measure the gas concentration, pressure, and mining traffic data, formulas and gas scalar formula and calculated according to the mixing amount of the standard conditions calculate the mixed volume and gas scalar, automatic storage is displayed. CWC3 portable gas drainage multi-parameter analyzer is used for the diameter D ≤ 100mm gas drainage pipeline parameter determination intelligent measuring instruments, particularly applicable to the drill field a single borehole sealing, sealing drilling parameters determination, is a portable mining intrinsically safe apparatus, proof mark Exib I, the determination of parameters including gas flow, gas concentration and pipe negative pressure, while the determination of drainage pipe in the mixed gas flow and the flow of pure methane. Determination of all the data can be stored, displayed and printed. The instrument has automatic power-down protection, and power supply undervoltage indication. Instrument data storage capacity, can store 100 sets of measured data, 300 groups of single-parameter measurement data. 
 Performance characteristics of 

 Instrument comes with its own vortex flow sensors, self-contained, without addition, with the orifice plate, the average rate of pitot tube, flow coefficient is directly solidified in software, the user can not change, this can be avoided due to mismatched coefficients of the measured data is not accurate 
 Easy to use. Users simply connect to hose and instrument measurements 
 Resistance loss is small, a small influence on the gas flow field 
 Reliable, high measurement accuracy
