Wireless Water System Monitoring Recording Telemetry Unit, Customizable and Rugged

Collecting, analyzing and understanding data from networks of recording sites is a challenging task. Telog’s recording system, the Telog RS-33u, offers you a versatile, economical and comprehensive solution to keep up with the data acquisition demands of today. 

The Telog RS-33u provides real-time monitoring and alarming of instruments and sensors in a system package so flexible it can be customized for each application to provide you with the information you need in a concise, presentable format. 

The Telog RS-33u has low power requirements and automatically monitors level, flow, pressure and water quality sensors. Data is forwarded wirelessly to a host computer operating Telog host application software, Telogers for Windows or Telog Enterprise. Data communication may be scheduled frequently (e.g. daily, hourly, every five minutes, etc.) and/or immediately in response to site alarm conditions. 

The Telog RS-33u supports multiple sensor interface options including RS-232, RS-485, analog and digital inputs. For example, when connected to an open-channel flow meter via RS-232, the RTU can interrogate the meter for it’s most recent level, flow velocity and battery voltage measurements. PLCs, flow meters, Sondes, etc. are also supported using a generic MODBUS client. The new MODBUS interface can be configured easily within Telog’s Enterprise software.

Telog also provides optional sensors that may be directly attached to the Telog RS-33u including ultrasonic and pressure level, water quality Sondes, pH and conductivity, temperature, level switches and a rain gauge. 

Wireless communication is supported via packet switched cellular (e.g. 1xRTT or GPRS).

The RTU is powered from a single, 6-volt lantern battery providing an operating life of six months to two years depending on sensor interface and call schedule.
