The issue you're experiencing with the level transmitter may be due to one of the following reasons:
1. Sensitivity adjustment: The sensitivity setting of the level transmitter might need to be adjusted based on the tank height and empty/full levels. This can cause discrepancies in the readings, especially when the tank is fully empty. Consult the manufacturer's manual or contact the supplier for guidance on making these adjustments.
2. Calibration: If the level transmitter has not been properly calibrated, it may display incorrect readings, particularly at the minimum levels (tank empty). Check that the transmitter has been calibrated according to the manufacturer's instructions and repeat the process if necessary.
3. Wiring or connection issues: Ensure that all wires and connections are correctly connected and secure. Check for any damaged or corroded wires, as well as any loose or broken connections that may be causing intermittent readings.
