HummBox Level Pressure is a piezo sensor, connected via Sigfox or LoraWan, self-powered, for continuous level monitoring in wells, tanks, and boreholes. Level measurement is carried out by differential pressure measurement between the liquid surface and the position of the submersible transmitter.
Applications :
- Pressure measurement in boreholes, tanks, sanitation.
Main features :
Temperature compensated and reliable pressure measurement
Sensor for sanitation environment (option)
LPWAN communication (Sigfox ou LoRaWAN)
European design made in France
Benefits :
- Low total cost of ownership
- Reliable data measurement
- Boost battery life
- Dual mode LoRa Sigfox for more flexibility
