1. introduction
LWGY series gas turbine flowmeter is learned the flow meter at home and abroad advanced technology optimized design,It is combination of the Gas mechanics, fluid mechanics, electromagnetism, etc theory to reserch and development the newest and high accuracy of temperature, pressure and flow transducer and intelligent flow totalizer. Have the performance of excellent low pressure and high pressure. Also have Variety of modes of signal output and low sensitivity of fluid disturbance. It is widely used in measuring in Natural gas, coal gas, liquefied gas, light hydrocarbon gas and other gases.
2. Features
2.1 alloy turbines has higher steady flow and corrosion
2.2 imported high quality bearing, long service life.
2.3 to keep the instrument security, measuring room and ventilation room were isolated.
2.4 It can be detected measured gas’ temperature, pressure and flow.
2.5 widely flow rate range(Qmax/Qmin≥20:1), good repeatable, high accuracy, low pressure loss.
2.6 intelligent instrument coefficients is more nonlinear correction.
2.7 built-in pressure and temperature sensors, high security, compact structure, good-looking appearance.
2.8 have the function of explosion-proof and protection-proof. The mark is ExdⅡBT6、ExiaⅡCT6. protection grade is IP65.
2.9 This system is low power consumption, 1 buttery 3.2V10AH can continuous working for more than 3 years.
2.10 N meter coefficient, the cumulative flow value power lost decade is not lost.

| specification | Display, output mode | Power supply |
| LWQ | The voltage pulse low level≤1V，High level≥5V，three wire system | External power DC12V-24 |
| LWQ－B |
With multipoint correction precisionat the same time it can show the instantaneous flow and cumulative flow double row liquid crystal display Like the follows： Q XXXX Four instantaneous flow rate（m3/h） XXXXXXXX Eight cumulative flow（m3） NOTE：cumulative flow is from 00.000000 started to count，Automatically expand display precision，the maximum is 999999.99。Cumulative flow values can be reset，Instrument coefficient, the cumulative flow value power lost decade is not lost. |

| LWQ－C | In the basics of the LWQ-B（the display type）plus to 4－20mADC current output. | External power DC24V |
| LWQ－D | On the LWQ-B（the display type）install temperature and pressure sensors, for the different conditions it can Automatic compensation correction operation. At the same time we can inquire the number of temperature/pressure and battery.Can output high frequency, low frequency voltage pulse signal, and 4-20 madc two wire current signal. | 3.2V10AH Lithium battery or DC24V power supply |
