Gas Cylinder Level Sensor FAQS

Frequently Ask Question

Gas Cylinder Level Sensor can only be installed at bottom center of the tank.
Since the ultrasonic wave is propagated vertically, the sensor can only be installed at the bottom center of the tank. If installed on the side where there is liquid, the measured reading is the diameter of the tank; If installed at the top, there is no reading.
A small amount of coupling agent needs to be applied before each sensor installation. The purpose of the coupling agent is to prevent air between the sensor and the tank wall, since air will prevent the transmission of ultrasonic waves.
