MODEL

SHOW,OUTPUT METHODS

POWER SUPPLY

LWQ

Voltage pulse: low level within  1V, high level≥8V,  three wires

External power DC12V-24V

LWQ-A

Standard analog signal (4∼20)m A correspond to the standard volume flow (0∼Qmax) m3/h,  two wires

External power DC24V

LWQ-B

Multi-points precision rectified, the double rows LCD screen  simultaneously showing the instaneous flow and accumulative flow, the method is as the following:

Q    

(four figures instaneous  flow m3

(eight figures accumulative flow m3)

Note: the count of accumulative flow is

      from 00.000000 to 999999.99.

its value will be keeping in ten years

as power cuts off

Lithium battery3.2V10AH

LWQ-C

It is more the current output 4∼20m A DC than LWQ-B ( display on site).

External power DC24V

LWQ-D

Based on the LWQ-B(display on site), it has the temperature and pressure sensors, and compensating and rectifying calculation for different flow states, simultaneously may inquire the values of temperature, pressure, electricity of battery etc., can output  the high frequency, low frequency voltage pulse signals and the two wires current signal 4∼20 m A DC.
