The Telog Ru-32imA provides real-time monitoring and alarming of pressure, flow sensors, valves, and meters found in harsh environments typical of water distribution and wastewater collection systems such as underground water vaults. When you combine the Telog Ru-32imA RTU with a Trimble Telog software option, you have a powerful system of wireless water infrastructure monitoring that is consistently delivering real-time data from the field straight to your desktop. Imagine…all your data on one platform straight to your computer screen.
 

In addition to monitoring the pressure on the two pressure channels, the impulse recording option feature of the Trimble Telog Ru-32imA unit stores the waveform of captured pressure transient (impulse) waves detected on the monitored network. The Trimble Telog Ru-32imA can store up to 125 events of variable duration that may occur over many months of on-site monitoring, recording up to a maximum of 20 minutes of pressure transient data at 30 samples/second. Impulse monitoring can be enabled on both pressure channels simultaneously, providing insight into impact and origins of such transient events.

Sensor Support
The Ru-32imA is a versatile eight channel RTU that can be supplied with one or two pressure sensors and can interface up to two digital inputs (pulse and/or event), one 4-20mA current loop from a process instrument, one analog voltage or potentiometer input, and two additional inputs to  capture the encoded register reading of single or dual water meters such as master meters and compound meters.

Wireless Communication
Using cellular technology enables unmanned monitoring of remote sites as well as instant updates and alarm notifications. The Ru-32imA uses a low power, LTE/Cat 1 cellular communication modem certified on multiple cellular systems. This ensures maximum coverage, reliability of service and alignment with cellular carriers technology roadmaps. Additional communication options are also available on request.

Collecting Data
The Telog Ru-32imA may be configured to call it’s server application on a schedule (e.g. once per day; every four hours, etc.) and/or in response to site alarm conditions (e.g. transient event, high or low pressure or level exceedance). The recorder can sample the sensor up to four times/second and store the data statistics (minimum, average, maximum or totals) at user defined intervals. Additionally, the Telog Ru-32imA recorder can sample the pressure sensors up to 30 times/second for transient detection on both channels. 

Packaging
The cellular modem, data recorder and battery are integrated into an IP67 rated, environmentally rugged enclosure weighing three pounds and measuring 8 x 8 x 4 inches (L x W x H). The unit is provided with a panel mount TNC coax connector and will support a variety of certified antennas. All connectors and fittings are watertight and the product is environmentally rated IP67 to 9.8 feet (three meters) of depth.

Battery Powered
The Telog Ru-32imA can be powered with internal battery or external DC power with internal battery backup. This is user selectable and the battery is  a single, user replaceable battery pack, Telog BP-4, providing an operating life of up to five years depending on the user-defined call schedule. A five year battery life example would be sampling two pressure sensors every 10 seconds and water meter registers hourly and transferring data to a host server on a daily schedule.

Software Support
Trimble Telog wireless recorders are compatible with all Trimble software applications, including Trimble Unity, 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.
