Wireless IoT Sensors enhance water monitoring capabilities

Trimble has introduced its Telog 41 Series of wireless, battery-powered sensors for water monitoring applications.

The new Internet of Things (IoT) sensors use low-power, Long-Range (LoRa) 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 programmes for better tracking, measurement, and reporting of water usage, sanitary and combined-sewer overflows (CSO/SSO), and flooding, leakage and non-revenue water (NRW).

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 LoRaWAN wireless networks that are being deployed globally to support a variety of IoT and smart cities applications.

LoRaWAN is a low-power wide area network (LPWAN) specification intended for wireless, battery-operated sensors or "Things" in regional, national or global networks.

The LoRaWAN wireless specification enables seamless interoperability among IoT sensors without the need for complex local installations to enable the rollout of IoT applications such as the monitoring of water pressures, water levels, rainfall and metered flow volumes.

"The IoT for water enables a step change in operational efficiency, compliance and sustainability for the water industry," said Adrian Newcombe, business director of Trimble's Telog solutions.

"With the Telog 41 Series of IoT sensors, 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."

The Telog 41 Series includes five new wireless IoT sensors that communicate the data at intervals between five minutes and 24 hours.

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 NRW.

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.

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 PE-41 pulse event recorder enables the monitoring of meter devices such as flowmeters within the network.

By retrofitting the Telog PE-41 to existing mechanical 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.
