Radar water level and alerts for stormwater pits.
Millimetre level radar depth, tilt, temperature and light readings from inside the pit, with alerts when pits are blocked or don't drain, water surges, the unit is moved or the temperature passes your threshold.
Built for the pit.
Sealed to IP68, 350 g, Ø125.1 x 76 mm.
Works from -40 to +85 °C.
Up to 10 years of battery life (up to 8 years with surge detection on).
Reports over LTE-M and NB-IoT. You set the reporting interval, from every 10 minutes to every 48 hours.
Water level from 200 mm to 12 m, at millimetre-level resolution.
Configure it from your desk or your phone.
Set intervals and alert thresholds remotely in Meridian and push firmware updates over the air. On site, the Matter Ops app commissions a unit by Bluetooth and updates its firmware from your phone.
Secure from sensor to platform.
Device-to-cloud traffic is encrypted with DTLS 1.2 (pre-shared key), firmware is cryptographically signed, and Bluetooth access requires challenge-response authentication. Pull readings into your own systems through the documented REST API.
