We provide on-site transient pressure measurement services to evaluate the presence, or not, of surge pressures in piping due to the action of a pump or valve. We use high speed PC based data acquisition software with built in analysis tools together that can act as both a diagnostic tool and a data logging unit.
Where necessary we will fabricate adaptors and specialist devices to enable connection to your piping, although we do not offer on site modification of piping using hot processes such as welding. With our standard arrangements we can measure pressure waves at up to 100 BarG.
The signal processing software that we use has in-built filter functions that can remove electrical noise, pressure fluctuations due to machinery that is not of interest, as well as any many other spurious signals, in order to capture the best possible signal where conditions are challenging.
Equally as important when trying to capture a clean signal that represents the pressure wave as it transits the measurement point, is to provision equipment that has a sufficiently high sampling rate and that this is matched by the performance of the transducer.
If these rates are not correctly matched, or are too low then the pressure wave will have passed the measurement location before the equipment responds.
By ensuring that the logging rate is high enough then the shape and characteristic of the transient wave will be correctly tracked.
After processing the results we will produce a written report highlighting the main findings and pointing out any areas of concern, such as high vibration on your piping, machine or structure. Where we think that specific devices, or equipment may help, or are needed, we will make recommendations as to what action you might take.
