摘要： A flowmeter incorporating a pressure differential member creating a differential pressure between an upstream flow path and a downstream flow path of a pipe. The flowmeter has pressure connecting lines located on either side of the pressure differential member and constituted by conduits issuing on the surface of the device. The pressures in the upstream and downstream flow paths are transferred to a differential pressure sensor constituted by two elastic surface wave oscillators supplying signals, whose frequency is proportional to the pressures. The signals are then transmitted to a mixer, whose output supplies a beat signal, whose frequency is equal to the difference of the frequencies of the signal supplied by the oscillators. This frequency difference is directly proportional to the differential pressure.

摘要： The invention relates to elastic surface wave pressure gauges.The gauge comprises a plate on which are located the electronic components of the gauge and a pressure sensor grouping the electromechanical elements on a header having connecting pins. The header is provided with a pressure inlet which traverses the plate.The invention is also applicable to the measurement of the pressures of fluids in order to optimize the supply to internal combustion engines. The pressure inlet is made of a rigid metal header and separately grounded for shielding of the surface acoustic wave electrodes to prevent "pull-in" where the oscillators inadvertantly lock on the same frequency.

摘要： A sensor of the type comprising two delay lines forming part of two oscillators whose output signals are mixed and in particular a surface acoustic wave sensor comprising a wafer made from a piezoelectric material comprising a calibrating device for calibrating the output frequency constituted by an additional delay line formed by a metal strip inserted in the connections of one of the oscillators. By means of a laser beam indentations are formed in this metal strip, thus causing an increase in the delay for adjusting the frequency of the output signals of the sensor to a predetermined value.
