Working principle:

This ultrasonic Water level gauge will launch data to the sensor as soon as it touches the object, so the requirement of the water tank must be regular, If use irregular tanks, the measured data may not accurate, the ultrasonic measured data may be your irregular tanks data protruding can data,

Usage:

a: The maximum depth that the sensor can measure is 5m (49.2ft)
b: This device can only be used to measure the depth of liquids, such as water, non-corrosive oil; Can not used in the diesel, petroleum.
c: This device is not waterproof, Even though it works fine in water splash or dew, this product is not completely water proof in heavy rain. It is highly recommended that a cover be installed above the unit.

NOTE:

1.The distance between transmitter bottom and highest water
surface should be over 50cm (0.5m or 1.64ft)
2. The tank bottom should be FLAT (Irregularly shaped bottom do not work)
3. Make sure the sensor installed in the middle and put Flat on the tank.
4) The maximum depth the unit can measure is 15m (49.2ft).
5. The radium of tank may affect the depth measurement
