Capture of pressure signal before importing  into HYDROSURGE: DCM



Pressure transient signals captured  are imported in HYDROSURGE any time a new significant hydro event happens by using the Data Conversion Module .

Pressure transient capture is ensured by disturbance recorders who isolate the transient signal in the continuous flow of information  from the pressure sensors.

Disturbance recorder captures any event leading to significant change in pressure fluctuations such as:

  • Absolute threshold overcoming,
  • Relative amplitude changes,
  • Self sustained cyclical pressure fluctuations.

Pre-trigger enable the pressure recording just before threshold overcoming for a better hydro diagnosis.

Mothrys interfaces with 3rd party disturbance recorders, like Yokogawa GX system, to ensure effective transient signal measurement and recording.
