To monitor the water pressure within any water distribution system, users can attach the HPR-2109e hydrant pressure
To monitor the water pressure within any water distribution system, users can attach the HPR-2109e hydrant pressure recorder on the 2½-in. hose nozzle outlet of a common fire hydrant. The rugged aluminum enclosure is approximately the same size as the hydrant nozzle cap.
Once installed, the recorder measures water pressure once every second with its internal pressure transducer. Users can determine how often such data is summarized for reporting. The recorder computes any combination of minimum, average, and maximum of the pressure measurement at each interval according to the selection of statistics and recording interval.
Data collection is accomplished via a watertight RS-232 connector accessible at the end of the recorder enclosure. There is no need to dismantle the installation and interrupt data recording to collect data.
