Quantity:

The R718PA22 is a wireless communication device that measures the liquid level with an ultrasonic liquid level sensor. Ultrasonic liquid level sensor installed at the bottom of the container may measure water, gasoline, diesel, and small, medium, and large capacity storage tanks (metal, plastic, glass material). R718PA22 main unit and the ultrasonic liquid level sensor communicate via the RS485 interface, and the detected data is sent to the other equipment shown which employs compliance with LoraWANTM wireless communication protocol standards.
