DF550 Ultraonic Level Sensor
Top Installation, Non-contact measurement
DF550 Ultraonic Level Sensor (NB-IoT, Lorawan, Sigfox, RS232, RS485, 0-5V, 4-20mA)
➽ 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. Furthermore it can calculate the volume of the container or the liquid.
➽ Low power NB-IoT/LoraWAN/Sigfox wireless Technology or 4-20mA/0-5V/RS232/RS485 output
➽There are with inner battery and external power supply version. The battery version can work for the projects where power supply is not so easy.
➽ Non contacted measurement, 2m/8m version can meet different measuring range
➽ Top installation, need drill hole.
➽ Option with battery for low frequency measurement, no need to connect power cable.
