Gas meters ZX-LWQ gas flow meter is learned at home and abroad advanced technology to optimize the design of the instrument, a combination of gas mechanics, fluid mechanics, electromagnetics theory and self-developed set of temperature, pressure, flow sensors and intelligent flow totalizer in one of the new generation of high-precision, high reliability gas precision measurement instruments, with excellent low and high pressure measurement of performance, a variety of signal output and low sensitivity to the flow disturbance, widely used in natural gas, coal gas, liquefied petroleum gas , measuring light hydrocarbon gases and other gases. LWQ gas meters by the national explosion-proof product quality inspection departments by GB3836.2000 "explosive gas atmospheres Electrical Equipment Part 1: General requirements", GB38362.2-2000 "Electrical apparatus for explosive gas atmospheres Part 2: Flameproof" d "" and GB3836.4-2000 "Electrical equipment for explosive gas atmospheres Part 4: Intrinsic safety" i "" inspection standard, proof mark ExdⅡBT6 (flameproof), EiaⅡCT6 (intrinsically safe). Suitable for containing ⅡA, ⅡB, 0 (intrinsically safe only) ⅡC class T1 ~ T6 temperature groups of explosive gas mixtures 2 dangerous places. LWQ Natural Gas Flow Meter Product Features: 1, using the new sensors, low starting flow, pressure loss, anti-vibration and anti-pulsating flow performance, easy corrosion, good reliability, long service life. 2, using the new microprocessor and high-performance integrated chips, high operational precision, machine powerful, superior performance. 3, the use of advanced micro-power high-tech, low power consumption machine. Both long-run with the battery-powered, but also run by the external power supply. 4, according to traffic frequency signals can be divided eight automatic meter factor linearity correction, the instrument may need to improve the accuracy of the user. 5, the use of EEPROM data storage technology, with storage and query capabilities historical data, historical data recording three to choose from. 6, the flowmeter meter can be rotated 180 °, installation is simple and convenient. 7, high accuracy, generally up to ± 1.5% R, ± 1.0% R. 8, repeatability, short-term repeatability of up to 0.05% to 0.2%, it is due to good reproducibility, in trade settlement is the preferred flow meter. 9, can be detected by detecting the gas temperature, pressure and flow rate, the flow rate can be automatic tracking compensation, and display of gas flow under standard conditions, real-time check of temperature, pressure, time, date and other data. Measuring media: natural gas, coal gas, liquefied petroleum gas, carbon dioxide, light hydrocarbon gas, gas, methane, nitrogen, air, compressed air and other low-velocity gas. Instrumentation Category: Natural Gas Flow Meter can be divided into N: sensor type, only the output pulse signal, without local display; A: transmitter type, only output 4-20mA signal, without local display; B: Intelligent Display Type The battery-powered (no signal output); C: intelligent display type, DC24V power output signal 4-20mA type; D: temperature and pressure compensation type, display pressure, temperature, flow, and remote 4-20mA output signal. LWQ meter meter usually with medium + medium + gas meters, meter classification, explosion proof or special requirements to name, such as gas meter, nitrogen flow meter, air flow meter, gas meter, high-precision gas flow meter, digital gas meter, smart gas meter, pipeline gas meter, remote-type gas meter, intelligent integration type gas flow meter, temperature and pressure compensation type flow meter, temperature and pressure compensation integrated natural gas flow meter, explosion-proof type gas meters.
