The method of field calibration is not correct.  Calibrate again.2. The flow rate on the meter is below the lowest. Increase the flow rate.3. The flow meter is blocked by the dry liquid out the impeller and clean it carefully and make sure the impeller turns freely.4. The impeller is wrapped by the sealing material. Remove the meter and make sure the impeller turns freely.5. Too close to the impeller.  Install properly6. Too close to the motor or electronic noise environment  Install properlyThe reading numbers faded or blanked out.1ery is exhausted or not connectedCheck the batteries or even replace themFlow rate is normal but the meter can not count. Press the button of DISPLAY, the meter start.1. Field calibration is not correctbrate againageList:1 x Turbine Flow meter
