Wireless Hydrant Pressure Recording

Wireless Hydrant Pressure Recording

Telog's original line of hydrant pressure recorders was designed to replace costly, high maintenance chart recorders for monitoring water pressure in distribution systems. The Telog HPR-32 series is Telog's next generation of paperless, hydrant pressure recorders and incorporates wireless technology for hands-off data transfer straight to your desktop.

Applications Include:

  • Investigating pressure complaints
  • Fire flow testing
  • Pressure loss tests
  • Calibrating hydraulic models
  • Monitoring system pressures
  • Hydrant capacity testing
  • High speed sampling to 20 s/s


Wireless Communication
The power of every 32 series recorder from Telog is wireless data transfer capability. Using wireless technology enables unmanned monitoring of remote sites as well as instant updates and alarm notifications.

The Telog HPR-32G and HPR-32iG recorders are equipped with an optional GPS feature. GPS combined with Telogers Enterprise web module allows users to spatially correlate HPR field data automatically. When the Telog HPR-32 calls in, it can be instantly tied to the HPR's location and displayed on the map.

Impulse Detection
The Telog HPR-32i and HPR-32iG are pressure impulse recorders that capture and store the waveform of water hammer and negative pressure transient events.

Battery Power
All Telog hydrant pressure recorders have low power requirements so they can be battery operated. The Telog HPR-32 series uses a single, user-replaceable D cell lithium battery. At a typical two calls per day, the battery will last up to five years.

Packaging and Installation
Every hydrant pressure recorder from 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.
