e+h ultrasonic L-flow meter reports error 91W, C281 (initialization)
Thread Content
The e+h ultrasonic flow meter model 91W is showing an error code C281 (initialization). The value keeps fluctuating – what should I do? Even after turning off the power, the problem persists; is there any solution? Please help
Mu Weiqiang, I can run into you even here. Come down and have a drink
How did you resolve this error code?
First, grind the pipe again to remove rust. Second, apply some more coupling agent. Third, whether the pipeline parameters are entered correctly in the table header leads to inaccurate installation locations. Fourth, is the installation location causing bubbles to form in the pipes from time to time? All of the above factors can lead to C281, which means initialization; in practice, it involves finding a stable signal again.
