MODEL SHOW,OUTPUT METHODSPOWER SUPPLYLWQVoltage pulse: low level within 1V, high level≥8V, three wires External power DC12V-24VLWQ-AStandard analog signal (4∼20)m A correspond to the standard volume flow (0∼Qmax) m3/h, two wires External power DC24VLWQ-BMulti-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 battery3.2V10AHLWQ-CIt is more the current output 4∼20m A DC than LWQ-B ( display on site). External power DC24VLWQ-DBased 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.
