15 SLPG01 ULTRASONIC LPG TANK LEVEL SENSOR Description Technical Specification

SLPG01 Ultrasonic LPG Tank Level Sensor with analog voltage output adopts the acoustic reflection principle of the LPG tank level through a special conductive elastomer couplant to the metal LPG tank. It uses a circular rare earth magnet to attach to the under-face (bottom) of the LPG tank. Fitted between the Acoustic sensor and the tank is the special conductive elastomer couplant material. Inside the ultrasonic housing is a calibrated thermistor. The system sensor uses special ultrasonic processing technology. The echo signals are detected by the probe after being reflected back from the liquid surface. The echo signal is processed by the proprietary algorithm and the time is calculated. The system calculates the level of LPG according to the formula. There is no special requirement on the tank size. Installation 1. The sensor needs to be placed in the centre at the bottom of the LPG Tank. Please make sure there is no loose paint or debris at this point. 2. Clean the bottom surface of the LPG tank. If the metal tank has a thick or over- painted coating, the surface of the detecting point has to be clean and polished. 3. Place the couplant pad between the sensor and bottom of the tank. 4. Fit the alloy housing and magnetic ring to bottom of LPG tank. This is a strong connection which compresses the couplant material. 5. Check that the LED is flashing, as this confirms that it is good connection.
