What to do if my Greyline Instruments Measuring Instruments show reading when there is no flow?
- CCaitlin BlanchardAug 3, 2025
If your Greyline Instruments Measuring Instruments display a meter reading despite there being no flow, it could be due to several reasons. First, erratic measurements might be caused by electrical noise or poor signal quality. Try setting the Calibration/Damping to 5% and, with zero flow, use the Setup/Tare function. Another potential cause is Variable Speed Drive interference, so follow the drive manufacturer's wiring and grounding instructions, or try relocating the flowmeter, sensors, and wiring away from the VSD. Finally, check the sensor cable connections to ensure they are correctly connected and tightened.
