Last week at WEFTEC in New Orleans, Trimble announced the launch of a new line of wireless, battery-powered sensors for water monitoring applications.

The Telog 41 Series uses innovative low-power, Long-Range (LoRa technology) wireless communications to remotely measure and monitor water, wastewater, and groundwater systems including water pressures, flows, levels and rainfall volumes.

As part of a smart water infrastructure, the Telog 41 Series wireless sensors work in combination with Telog cloud-hosted and on-premise software to allow utilities to more easily and economically deploy wireless monitoring. The sensors extend across a utility’s existing monitoring programs for better tracking, measurement and reporting of water usage, sanitary and combined-sewer overflows and flooding, leakage and non-revenue water. The sensors can be deployed to enable utilities to address many of the significant challenges they are facing due to drought and water shortages, storm events and flooding, budget constraints, and environmental regulations.

The Telog 41 Series sensors leverage LoRa technology to operate on wide area wireless networks that are being deployed globally. That allows for seamless interoperability among sensors without the need for complex local installations. It has been adopted by network providers across the U.S., Europe and Asia.

“It enables a step change in operational efficiency, compliance and sustainability for the water industry,” says Adrian Newcombe, business director of Trimble’s Telog solutions. “With the Telog 41 Series, utilities now have the ability to monitor areas of their network that would have been cost prohibitive to reach in the past. And with the ability to wirelessly report data at resolutions down to five-minute intervals, water managers have much deeper visibility into their operations. This is essential for enabling utilities to transform how they operate their distribution and collections networks.”

The Telog 41 Series includes five new wireless sensors:

Pressure Monitoring — The Telog PR-41 Pressure Recorder provides utilities with visibility of their water system pressures ensuring that they can operate the network to meet customer needs, regulatory requirements and manage non-revenue water.

Level Monitoring — The Telog WL-41 Level Recorder allows utilities to monitor water levels of underground aquifers, reservoirs and water towers, ensuring that they have a real-time view of the water resources available and stored within their network.

Flow Monitoring — The Telog MTU-41 Meter Telemetry Unit enables utilities to monitor water flows in their system by collecting the values from a flow meter register and reporting the computed  interval flow volume. The Telog MTU-41 ensures that the utility has an up-to-date view of flows, while improving efficiencies with the elimination of manual reads.

Pulse/Event Monitoring — The Telog PE-41 Pulse Event Recorder enables the monitoring of meter devices such as flow meters within the network. By retrofitting the Telog PE-41 to existing mechanical meters (e.g. flow meters) in the network, the utility can gain near real-time data on parameters such as flow that were not previously possible, while driving efficiencies by removing the need for manual reads.

Rainfall Monitoring — The Telog RG-41 Rain Gauge allows utilities to continuously gather data on rainfall within their service area. The Telog RG-41 monitors the output of a tipping bucket rain gauge and reports the rainfall intensity so utilities can understand the intensity and distribution of rainfall and its potential impact on their network.

Key common features of the Telog 41 Series sensors include:

  • Low cost relative to traditional cellular remote monitoring products, allowing utilities to deploy sensors in higher numbers and to distribute them throughout their distribution and collections networks.
  • LoRa wide area network wireless technology ensuring that sensors call in at high frequency while still retaining long battery life (four to seven years).
  • Configurable alerts and alarms for automated event detection and reporting.
  • Powered by a single, user-replaceable C-size lithium battery; no need for on-site power and simple to maintain.
  • Small size, rugged and easy to install.
  • Compatible with Telog cloud-hosted and on-premise software.

The Telog 41 Series is expected to be available in the fourth quarter 2016 from Trimble’s Telog authorized partners and distributors.
