LWGY series Turbine flow meter
Product Category
1. LWGY series can be divided into two categories by function:
l Turbine flow sensor / transmitter
l Intelligent integration Turbine Flowmeter
2. Function illustration:
Ø Turbine flow sensor/ transmitter
This kind of products have no scene display function,only produce signals to transmit output to far distance. The flow signals can be divided into pulse or current (4-20ma) signal. This instrument has low price, high assemble, small size, so can be applicable to match second displayer,PLC,DCS so on computer control system to use.
According to different signal outputs, its can be divided into LWGY-N and LWGY-A types.
² LWGY-N sensor
12--24V DC power supply, three wires pulse outputs,
high level≥8V, low level≤0.8V, signal transmission distance≤1000M.
² LWGY-A transmitter
24V DC power supply, two wires current (4-20mA) signal output, signal transmission distance≤1000M.
Ø Intelligent integration turbine flowmeter
It adopts an advanced super-low power consumption single-chip microprocessor technology to make up of new intelligent flowmeter with turbine flow sensor and accumulative calculation displayer integration. It has many obvious advantages which are double-row LCD display at the scene, compact structure, direct and clear reading, high reliability, anti-interference from outside power, anti-thunder attack, and low cost ,etc.
It has the instrument factors' three points rectified, non-linear intelligently compensated, and revision at the scene.
High clear LCD display simultaneously shows both instant flow rate (four valid figures) and accumulative flow rate (eight valid figures, and accumulative flow rate (eight valid figures with reset). All valid data can be kept for ten years. This kind of turbine flowmeters all are explosion-proof products, and the explosion-proof class is ExdIIB6.
This type of turbine flowmeters can be divided into type LWGY-B and LWGY-C in terms of supply power and the remote signal transmitting methods.
LWGY-B type: supply power 3.2V10AH(Lithium battery) can continuously run more than four years, but no signal output.
LWGY-C type: supply power 24V DC outside, output normal two wires current signal (4-20 m A) , and can add RS485 or HART communication according to different scene demand

If you are not sure which model meets your requirement.
1. About Flow meter---what is the medium that you need to measure? What is the flow rate? Pipe diameter?
2. About Pump---what is the medium that you need to pump? Diesel, petrol, lpg gas or others? What is the pipe diameter, flowrate, power etc. ?
3. About Nozzle---what is the medium that you need to pump? What is the size ? thread NPT or BSPF ?
4. About LPG compressor---what is the intake pressure, discharge pressure, flowrate, power, voltage etc.? What is the volume of the flow meter?
