UTM Sensor Calibration

UTM Sensor Calibration UTM CALIBRATION FIELD REFERENCE Set the sensor mV/inch value for the product in the tank. The monitor converts the sensor signal into a level reading — the right mV/inch keeps that reading accurate. Calibrations don't need to land exactly on target; anywhere inside the acceptable range is good

Calibrating in four steps:

1. Verify the sensor - In Unify, find the serial number on the Devices tab and confirm the Sensor Interface Box. Pick the correct sensor option if it isn't already set. 
2. Find your product - Look it up in the table above. Note the target mV/inch and its acceptable range.
3. Enter the value - Set the sensor mV/inch in Unify. Keep OAR fixed at 500. Land inside the range — exact target not required. 
4. Confirm the reading - Check the device level against the actual tank level. If it's off, re-check the product's SG and the sensor box before re adjusting.

Product not in the table?

Ask the customer for the product's specific gravity — it's usually on the Material Safety Data Sheet (MSDS), or can be found online. Then calculate it yourself: mV/inch = SG × 25.4. The acceptable range is that result ± 2 mV/inch.
