Tank GX Reading Always 1v

Hello. I have a tank GX plugged into my RPi based set up. I have this sensor: Longzhuo Liquid Level Transmitter, TL-136 Liquid Level Transmitter Water Level Sensor Detector 12-32VDC 4-20mA Signal Output for Precision Measuring(1/2/3/4/5M)(0-2M) https://amzn.eu/d/6hyLNjz

The signal from the tank reads 1v continuously no matter how full or empty the tank is

What am I doing wrong? Thank you

In the settings menu for the tank sensor have you selected "current" for the sensor type?

It was voltage I’ve just changed to current and it’s 0.5 I topped up waited a few mins and still reads the same. Dumped some water and the same again.
