What is high-frequency pressure monitoring?

High-frequency pressure monitoring is an approach in pipe pressure monitoring related to increasing the frequency of pressure sampling in case of a pressure change.

ThingsLog LPMDL-110X data loggers can detect pressure changes and switch on into high-frequency pressure monitoring mode.

The High-frequency pressure monitoring mode is driven by two parameters – high-frequency sampling rate and high-frequency transmission mode.

If, for example, the reading interval is set at 1-minute, a 1-second spike in bandwidth utilization will be completely flattened and impossible to diagnose because 1-second represents only 1.7% of the total monitoring time. In a typical 5-minute reading cycle of most monitoring systems, those critical seconds will appear as little more than 0.33% of the total elapsed time — well below the radar of most systems. Nevertheless, this 1-second spike is of sufficient duration to perform damage, introduce leaks, brake pipes and lead to an increase of NRW – Non-revenue waters.

With ThingsLog such spikes are automatically detected and the pressure monitoring frequency is auto increased.

High-frequency pressure monitoring is automatically switched off once the logger detects that the pressure is back to the normal “average” value.
