Wireless IoT Flow Meter Totalizing and Pump Run Time

The Telog PE-41 establishes a new standard in low power, wireless recorders for pulse and event recording. It allows utilities to retrofit a cost effective sensor to monitor existing mechanical flow meters and pumps in the field, providing an up to date view of flow and pump run times/duty cycles.  

By deploying Telog PE-41s for bulk flow meters and pumps in their network, utilities can dramatically improve their insight into network behavior while achieving significant savings in operational costs.

The Telog PE-41 continuously monitors the output of a contact closure, pulsed output or event output device in user defined time increments then transfers the data automatically to a central host computer on a user defined schedule over a LoRaWAN™ network.

Packaged within a 4.7”x3.2”x2.2” NEMA 4x rated environmental enclosure, the Telog PE-41 is small enough to install almost anywhere. Because the antenna is enclosed within the Telog PE-41, the only connection required is the meter or pump being monitored. 

The Telog PE-41 uses a low power, long range LoRaWAN communication protocol which is an industry standard for the emerging Internet of Things (IoT). Making data calls every 15 minutes, the recorder can operate an average of 5 years on one user replaceable ‘C’ cell Lithium battery. This significantly reduces the cost of ownership as the need to visit remote sites for frequent battery changes is removed.

The Telog PE-41 is compatible with all Telog software applications, including Telog Online, Telog Enterprise and Telogers for Windows application software. This ensures that utilities have a complete solution addressing all their remote monitoring needs across their operations, delivered in a manner that suits each individual utility’s operations and IT needs.
