Wireless, Battery-Powered Hydrant Pressure Monitoring

The Telog HPR-32A is an ideal pressure monitoring solution for pressure concerns, fire flow testing and hydraulic model calibration.

Trimble Unity software combined with Telog wireless hydrant pressure recorders provide a GIS-centric cloud and mobile platform for monitoring system pressures, and trends, min, max and average pressure history at any user defined interval. Telog hydrant pressure recorders can store data internally for many months and wirelessly transmit on a defined schedule to provide alerts and alarms in response to pressure faults, delivering a complete  solution for proactive pressure and leakage monitoring and management. 

Wireless Communication
The power of every 32 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 HPR-32A uses
a low power, LTE/Cat 1 cellular communication modem certified on Verizon Wireless.

Battery Power
All Trimble Telog hydrant pressure recorders have low power requirements so they can be battery operated. The HPR-32A series uses a BP-4 lithium battery pack. At one call per day the battery will last up to five years.

Packaging and Installation
Every hydrant pressure recorder from Trimble Telog is a low-profile, rugged unit that is easily installed by one person on a standard 2.5 inch hose nozzle outlet. For ease of mind an optional security cover can be used to prevent
vandalism. Once installed, data is immediately available using Telogers for Windows or Telog Enterprise software.

Software Support
The Trimble Telog HPR-32A is compatible with all Trimble software applications, including Trimble Unity, Telog Online (cloud), 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.

Telog HPR-32A applications include:

  • Customer pressure complaint investigation

  • Pressure loss testing

  • System pressure monitoring

  • Calibrating hydraulic models

  • Fire flow testing

  • Hydrant capacity testing

  • Sampling to 4 samples/second

The HPR-32A is also available with impulse event capture capability. Click here for more information.

Monitoring Progress: Nailing Down Water Hammer And Its Implications

By Telog, A Trimble Company

If you don't know what a water hammer is, well, that's a big part of the problem. It's an all-too-frequent issue for water systems everywhere, striking in pipelines that are growing more susceptible to failure as they age.
