More info please. Type of plc, tank, product etc. Detailed questions lead to accurate answers.

You will also need to identify the type of sensor used (i.e. d/p cell or float), how the sensor is connected to the tank, and the elevations. Also, what kind of loop is being used (i.e. 4-20 mA, wireless, etc...). A good installation drawing would be helpful. This is due to the possible elevation offsets that may come into play. Also is this tank pressurized and does it have a liquid/vapor interface?

These things will need to be known before any further information can be given.

Hope this helps
