LWGY - 4 turbine meter scale no display solutions

Abstract: LWGY - 4 turbine meter scale show no solution information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. LWGY - No display solutions (4 turbine flowmeter 2) Three, flowmeter measurement values do not tally with the actual value 1. Shanghai automation instrument nine plant root cause analysis ( 1) LWGY - 4 turbine flowmeter transmitter circuit boards are in good condition; （ 2) When the liquid flow rate is too low. More flow meter manufacturers choose model price quote you are welcome to inquire, here is LWGY - 4 turbine flowmeter solutions the article details the no display of the scale. LWGY - No display solutions (4 turbine flowmeter 2) Three, flowmeter measurement values do not tally with the actual value 1. Shanghai automation instrument nine plant root cause analysis ( 1) LWGY - 4 turbine flowmeter transmitter circuit boards are in good condition; （ 2) When liquid flow rate is too low, the tiny air bubbles in the liquid being measured, the bubble rising gradually gathered over the pipe, the liquid circulation area changes, gas long will produce interference signals, affect measurement accuracy. （ 3) Turbine flowmeter signal cable connection is not good phenomenon or cable insulation performance degradation in use process cause inaccurate measurement; （ 4) The parameter setting of the converter is not accurate. 2. Solution ( 1) Check whether the transmitter circuit board is intact. If the junction box into the water or corrosive liquid corrosion under test, which can lead to electrical performance degradation or damage. A circuit board should be replaced at this time. （ 2) Ensure the measured liquid in the pipe flow in zui low flow above the threshold value, so that the transmitter can work normally. （ 3) Check the signal cable connection and cable insulation is in good condition, if appear signal cable loose phenomenon, reconnect it can; If the check to the cable insulation do not conform to the requirements of the insulation, you need to change new ( 4) To set of converter set value, and calibrate the zero, the full value of converter. Four super full range 1, output signal. Cause analysis, the causes of such failure is roughly: ( 1) Error signal cable wiring or cable connection is broken; （ 2) The parameters of the converter set is not correct; （ 3) Converter and sensor models don't match. 2. Solution ( 1) Check the signal circuit connection is normal or not, if the signal circuit disconnect, the output signal will be super full value, should be properly connected signal cable anew at this time. At the same time, need to check whether the insulation of the cable in good condition, if have do not conform to the requirements, the need to change a new cable. （ 2) The parameters of the detailed check converter set and zero and full compliance with requirements. （ 3) Check to the converter and sensor models don't match, you will need to exchange with the manufacturer. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
