4. Functionality
The NV-R718PE functions as a wireless data acquisition and level monitoring device. It measures the distance between the sensor and the liquid or solid surface using ultrasonic pulses. The sensor emits an ultrasonic wave, which reflects off the surface and returns to the transducer; the time-of-flight is used to calculate the level or distance.
Simultaneously, the device reads analog current signals (4–20 mA) from up to two external sensors, such as pressure transmitters, flow meters, or temperature probes. These readings are digitized and transmitted wirelessly via the LoRaWAN network to a central server or cloud platform.
Use Cases and Applications:
- Water and wastewater level monitoring in tanks, wells, and reservoirs
- Industrial process control for chemical or fuel storage tanks
- Agricultural irrigation system monitoring
- Smart city infrastructure (e.g., flood detection, drainage monitoring)
- Remote environmental monitoring stations
