I have a 2" sensor connected after a 2" wye. One branch of the wye steps down to 1" to a frag tank and a manifold. The line to the manifold has a 1" sensor. The other end goes to the 2" sensor then steps down to 1-1/4" and returns to the DT.
The pump is a Jebao DCP18000 that has a strainer on the input. Yesterday after shutting the pump down the sensor stopped reading. The sensors plug is attached correctly and I'm not seeing a loss of flow to the display or an increase to the drag tank. The display has a beananimal drain that has not needed to be adjusted.
Today I shut the pump down and let the pressure build up before opening the main return line up. I then repetitively closed and shut the line. No change. I know the turbine has to be spinning or there'd be drag and a flow change that would require an adjustment with the bean drain. The sensors were all cleaned last month.
Any thoughts on what could be the problem?
