i have used level transmitter in starch cooking preparation tank. tank total height 2mtr.sometime LT display shows some error value when tank is fully empty and diaphragm side i already checked okay no problem in diaphragm area. field cable checked 24volt and mA shows correct value while tank empty mA is 4mA. 4mA i needed that 0% but display showing 10% or 15% percentage values are varying continously

Answer / Mahesh Kumar Bhujel

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.
