Wireless Water System Monitoring Recording Telemetry Unit, Customizable and Rugged

Collecting, analyzing and understanding data from networks of recording sites is a challenging task. The Telog’s RS-33u recording system 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.

Communication Options
The power of every 33 series recorder from  Trimble Telog is wireless data transfer capability. Using cellular technology enables unmanned monitoring of remote sites as well as instant updates and alarm notifications. The Telog RS-33 systems employ a Telog proprietary, low power m2m cellular modem certified for operation on theVerizon Wireless and Sprint cellular networks in addition to an Ethernet option.

Collecting Data
The RS-33u supports multiple sensor interface options including RS-232, RS-485, one analog and one digital input. For example, when connected to an open-channel flowmeter via RS-232, the RTU can interrogate the meter for it’s most recent level, flow velocity and battery voltage measurements. PLCs, flowmeters, 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 RS-33u including ultrasonic and pressure level, water quality Sondes, pH and conductivity, temperature, level switches and a rain gauge.

Packaging
The cellular modem (if used), antenna, data recorder and battery are integrated into an environmentally rugged NEMA 4x enclosure measuring 13”L x 11”W x 6”H [330mm x 279mm x 152mm].

Power Options
The Telog RS-33u system has low power requirements allowing for a variety of power options. These are utility power with or without battery backup UPS function, solar, external DC or primary battery.

Software Support
Trimble Telog wireless recorders are compatible with all Telog software applications, including Telog Online (cloud), Telog Enterprise and Telogers for Windows application software. This ensures that utilities have a complete solution addressing all their remote monitoring requirements delivered in a manner that suits each individual utility’s operations and IT needs.
