Wireless, Remote Water System Monitoring with Rugged, Battery Powered IP67 Rated Recording Telemetry Units

The Telog Ru-32m is a versatile, five channel RTU that can be supplied with one or two pressure sensors and can additionally interface up to two digital inputs (pulse and/or event) and one analog voltage or potentiometer input. Applications include capturing the encoded register reading of single or dual water meters such as master meters and compound meters as well as monitoring water system pressures, underground water level, mag meters, Pressure Reducing Valves (flow and pressure) and Pressure Relief Valves.

The Telog Ru-32m is provided with the Telog WM/C cellular m2m modem which is certified on the Sprint and Verizon Wireless networks in the US and the Bell Mobility network in Canada. Internationally, the unit may be provided with the Telog WM/G modem for operation on GSM networks.
