Telog’s Hydrant Pressure Recorder, the HPR-31, monitors water pressure
within any water distribution system. The HPR-31 replaces costly, high
maintenance chart recorders in applications such as pressure complaints,
valve performance, model validations, water hammers and negative
pressure investigations.The simplicity of the
compact, battery-powered HPR-31 enables you to put it to work within minutes
of unpacking. The HPR-31 attaches onto the 2.5 inch hose nozzle outlet of a
common fire hydrant. The rugged enclosure is low profile and an optional
security cover is available.
Once installed, the HPR-31 measures water pressure at
user programmable rates up to four samples per second with its internal
pressure transducer. You can determine how often such data is summarized for
reporting. The recorder computes any combination of minimum, average and
maximum pressure measurement at each interval according to your selection of
statistics and recording intervals.
Recorded data may be gathered via an RS-232 connector
using a hand-held Palm DTU (Data Transfer Unit) or a
laptop. The DTU is especially convenient for gathering data from several
hydrant pressure recorders. At times when on-site data evaluation is
required, a laptop and Teloggers for Windows software, is all you need.
