Sigfox DF550 Top installation Ultrasonic Liquid Level Sensor
The DF550 is ultrasonic level (distance )sensors which can measure the air height directly and calculate the liquid or solid height based on the total height of the container (distance). It is applicable for the close container or open container, or even the river. Through the built-in Sigfox module, the level data is sent to the network server through the Sigfox gateway. Generally we divide the frequency band into RCZ1, RCZ2, RCZ3, RCZ4 and so on.
