LQW-B/C type intelligent integration gas turbine flowmeter
Material:stainless steel
Accuracy: ±1.5%R±1.0%R
Repeatability:0.05%~0.2%
Explosion class:ExdIIBT6
Output signal:2-wire system 4~20mA(LWQ-C type)
Local display: yes
Note:LWQ-B type power supply adopts 3.2V10AH Li battery(can work for more than 3 years continuesely);non signal output.
LWQ-C type:power supply adopts 24VDC outer resouce,output 4~20mA standard 2-wire system electric current signal. It also can add with RS485 or HART communication according to different needs.
Power-Off Protection: The instrument coefficient and the accumulative flow value can be saved for ten years without power
