Wireless Hydrant Pressure Monitoring

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

Battery Power: All Telog hydrant pressure recorders have low power requirements so they can be battery operated. The Telog HPR-32 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 the Telog Online Solution, Telogers for Windows or Telog Enterprise software.
