Transient Pressure Monitoring

Accurately measuring the operating pressure in a pipeline is an important aspect of understanding the system hydraulics and the effect of pressure surges

It is a well-known fact that pressure transients can have adverse effects on the integrity of pipelines. This is painfully evident when a water hammer causes a pipeline to fail.

However, most pressure transients occur without ever being noticed and can cause incremental damage every time a surge occurs. Accumulated damage of this nature can significantly weaken the pipeline.

There are two reasons why pressure should be monitored:

  • Finding pressure transients and their severity
  • Understanding how the operation of the pipeline affects pressure

There is a better way to monitor pressure

Conventional pressure monitoring technologies cannot always detect and quantify pressure transients ina reliable way, and they don’t provide a realistic understanding of the true condition in a pipeline.

Our transient pressure monitoring system provides an elegant solution to these challenges. We provide high-quality data on pressure transients without sending endless amounts of data during normal operating conditions. We continuously monitor pressure and report at user-defined intervals. When a transient is detected, the sampling rate is increased by up to 100 samples per second, which provides accurate readings of pressure that can be plotted over the duration of the entire transient event.

 

With traditional pressure monitoring technologies, the transient on the left would have been missed. However, with our system (right), the transient is recorded and accurately plotted.

Dallas Water Utilities

DALW is currently constructing Phase III of the Lake Fork Raw Water Transmission Main, which is composed of 108″ Prestressed Concrete Cylinder Pressure Pipe (PCCP).

Phase I of this line had been previously installed, but had failed a series of hydrostatic pressure tests. The failure of the pipeline to hold pressure above 190 psi suggested the presence of high pressure leak(s).
