DF550-LR-2000

The F550 is ultrasonic level (distance) sensors which measure the air height directly and calculate the liquid or solid height based on the total height of the container (distance). The resolution is 1mm or 0.1%FS (the bigger value). It is applicable for the close container or open container. Furthermore it can calculate the volume of the container or the liquid.

With LoRaWAN wireless module, the level data is sent to the network server via gateway. Finally user can monitor the realtime level remotely. It is optional for frequency 470Mhz(CN), 868Mhz (Europe), 915Mhz(USA), 923Mhz(Australia).

 

Application

F550-2-2000 ultrasonic level sensor with RS232 output , 200-2000mm measurement range, high resolution, can add Zigbee/Wifi/GPRS device inside (optional). Widely used in fuel station,water tank,agriculture,river, can measure any liquid or solid.

 
The F550 is one type of ultrasonic level sensor which measure the air height in the container directly and calculate the level height based on the total height of the container. The resolution is 1mm or 0.1%FS (the bigger value). It is applicable for the close container or open container. Furthermore it can calculate the volume of the container or the liquid. It is easy to integrate into the embedded system or SCADA
