DF556 Pressure Liquid
Level Sensor
DF556 is a pressure-based liquid level sensor, with wireless transmission module and battery.
With a submerged pressure transducer, DF556 can acheive 0.5% accuracy of the liquid height. The standard measurement range is up to 2.5m. For other cable length, please contact our sales.
It is integrated with wireless module like NB-IoT, LoRaWAN, Sigfox, CAT-M, GPRS, 4G-LTE and etc. Data is uploaded to cloud server in protocol TCP, MQTT, LoRaWAN or other customized protocol. Widely applicable for liquid tanks, sewage, industrial water, pool, rivers and etc.
