Telog's HPR-32i Pressure Impulse Recorder is an advancement of the company's HPR-32 Hydrant Pressure Monitor. In addition to the HPR-32's ability to record system pressures and trends, the HPR-32i captures water hammer and negative pressure event waveforms in a separate memory and downloads them wirelessly to Telog's host computer application. This recorder samples up to 20 water pressure samples per second, storing the waveform of impulse events detected by a rate-of-change detector. More than 300 events can be stored, each lasting from a few seconds to many minutes.
