daviteq WSLRW-ULC Lorawan Ultrasonic Liquid Level Sensor

FEATURES

LORAWAN COMMUNICATION
LoRaWAN communication standard to allow sensor connect to any LoRaWAN Gateway on the market.

10 YEAR BATTERY
Ultra-low power sensing technology from Daviteq with Ultralow power wireless technology allow the sensor can last up to 10 years with 02 x AA type batteries.

HIGH ACCURACY & STABLE
Advanced ultrasonic sensor with digital signal processing to deliver high accuracy and stable measurement of level or distance for liquid surface

IP68
For both indoor and outdoor applications

WSLRW-ULC is LoRaWAN Ultrasonic Level Sensor to measure the level of liquid surface of water, oil… This level sensor utilises the ultrasonic technology to measure the surface of liquid, the principle is to measure the time of flight of the ultrasound pulse in the air environment. The ultrasound pulse will be ejected from ultrasonic transducer, go thru the air and reaching the surface of liquid, then reflected back to the ultrasonic transducer, the measuring circuit will measure the time of flight of the Pulse then calculate the distance from transducer to the surface. With Ultra-low Power design and smart firmware allow the sensor can last up to 10 years with 02 x AA-type batteries (depends on configuration). The sensor will transmit data in kilo-meters distance to LoRaWAN gateway, any brand on the market.
