Smart Pressure Monitoring device, SPM
The SPM is an IoT-based smart pressure monitoring device that can be installed in underground shafts, power houses or nodes using a drilling assembly. Its IP68- rated housing ensures reliable operation even in extreme conditions.
The device can take two pressure measurements and receive a pulse signal via external connections, making it suitable for collecting water pressure and water measurement data in places where there is no power supply or where conventional GSM technology does not work. It has an internal battery and transmits the data to a dedicated server via LoRaWAN or NB-IoT network
Areas of use
- Wells and machine rooms – Pressure and water volume measurement
with a single device - New manholes, nodes – During installation or network reconstruction
- Metering and manholes – Reliable pressure measurement
- DMA areas – Zone boundary and zone lock monitoring
- End points, high and low points – Monitoring pressure changes
- Critical points – Monitoring pressure fluctuations and network loads
