The flexible membrane (50) is at least partially formed from conductive material, and the chamber (58) contains a fluid at a reference pressure.

Abstract: A pressure sensor that compensates for variations in temperature by having first (53) and second (51) chambers with first and second respective flexible membranes. The first and second flexible membranes deflect in response to pressure differences within the first and second chambers respectively. The first membrane is exposed to the fluid pressure (66) to be measured, such as the air pressure in a tire. The second membrane sealed from the fluid pressure, and, associated circuitry converts the deflection of the first flexible membrane into an output signal related to the fluid pressure, and converts the deflection of the second membrane into an adjustment of the output signal to compensate for the temperature of the sensor. By sealing the second chamber from the tire pressure, the deflection of the second membrane can be determined as a function of temperature. This can be used to calibrate the output signal from the first chamber to remove the effects of temperature variation.

The membrane (50) being at least partially formed from conductive material so that associated circuitry (34) converts the deflection of the flexible membrane (50) into an output signal indicative of the fluid pressure. The flexible membrane is less than 3 microns thick to allow the use of a high yield strength membrane material. A thinner membrane also allows the area of the membrane to be reduced.

Abstract: The invention relates to measuring equipment and can be used in data-measuring systems in oil-producing and oil-processing industries for the determination of multiphase flow composition, in particular, for evaluation of the well production rate. The invention is based on obtaining maximum data on the structure of the multiphase flow by its scanning in each measuring section by rotating high-frequency electric and magnetic fields with one common carrier frequency of the scanning signal.

The results of all measurements are used for calculating the correlation functions. The scanning signals generated by the rotating high-frequency electric field are scaled (signals are amplified by means of a normalizing scale factor). All four scanning signals are additionally processed by the microprocessor.
