Calibration (method 1)
Touch - Calibration (method 2)
Continuous monitoring of liquid levels has never been easier! Once installed the sensor needs to get to know the liquid and the vessel. Just fill the vessel and calibrate.
We made two ways to calibrate and they are both easy. One way is to just touch the white wire to DC-. Of course this can be done remotely in your PLC or manually.
The other way...just grasp the sides of the sensor! Not kidding. It is that easy.
There are two LED's. The green one lets you know the sensor is powered. The yellow one helps you know the status of the probe. When calibrating it blinks rapidly.
If the calibration was not valid the green and yellow LED's blink in an alternating manner. This lets you know to recalibrate the probe. This can happen if the vessel wasn't completely filled during the calibration, or something about the liquid or vessel has changed.

Conductive fluids in metal vessels or vessels that are earth ground yield the most linear results. The below graph show actual performance of a 12" long probe measuring tap water.
Non-conductive fluids yield less linear results. The below graph is the raw data of a 12" probe measuring a non-conductive liquid. Naturally, the data can be smoothed by firmware, however showing the raw data is important to engineers so here it is.
