Ultra-low Power Ultrasonic Level Monitor (3G / 4G Cellular)

The Site Sentinel® L1 is a specific variant of the Site Sentinel® data logger and RTU family, providing highly reliable, direct-to-host non-contact level monitoring in a single package, aimed at water utilities, city councils, agriculture, tidal monitoring, flood warning, open channel and irrigation sectors.

The Site Sentinel® L1 is designed for direct mounting above a water source such as a dam, channel, creek, basin, tank or manhole.  The Site Sentinel® L1 will then measure the water level with +/- 1mm accuracy and is non-contact, ideal in situations where deployment of other level sensing techniques is not possible.  Swift deployment is made possible thanks to the built-in front panel mounted ultrasonic level sensor, a true single box design that requires no external hardware.

The Site Sentinel® L1 operates on the cellular networks and can be ordered with either tri-band 3G or 4GX option, permitting use on CAT-M1 and NB-IoT Networks.

Host compatibility is ensured with integrated support for DNP3.0 slave and FTP data protocols.  The Site Sentinel® L1 is SIM card / Cellular network and Cloud Host agnostic, the end user is not locked into a single platform for data visualisation.

Complete control is handed to the user to allow custom data reporting and wake-from-sleep regimes to be configured to balance battery life against data logging and data reporting requirements.  Battery life of 5 years plus, depending on device configuration and reporting regime.

The Site Sentinel L1 product offers end users a cutting-edge hardware platform design and industry-leading ultra-low battery power consumption along with IP68 Rating.

The Site Sentinel L1 product is equipped with both Internal and External Antenna connections and is supplied with its first battery pack, stainless-steel quick release mounting bracket and installation kit.
