Put the transducer 24" up from the bottom of a standing pipe. Make the pipe tall enough to emulate the tank. Put a fitting for vinyl tubing and a valva at the bottom of the pipe and a clear tube attached to the outside of the pipe for it entire length or more. Fill the stand pipe with whatever is in the tank and as you let the liquid out of the pipe with tha valve located near th bottom, take instrument readings and stand pipe level readings from the sensor center line to the ligiud surface in the stand pipe for comparison in about twenty or more near equal steps across the expected range of the tank. These readings may or may not be linear and this is the only way to be sure of what gauge output is compared to the liquid level.
