Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


The development of a “dipstick probe” for measuring the position of phase interfaces in high temperature and pressure oil/water separators is described. This uses dual modality (capacitance and ultrasonics) measurement for this difficult application.
The issues of material selection for use in the aggressive high temperature environment are presented. In particular the problem of sensor materials was overcome by the use of thick-film and ceramic materials for all sensor components. A novel combined ultrasonic and capacitance thick-film sensor is described.
Finally, the construction of the probe is described, together with the test programme to be undertaken.
