Abstract: An improved ultrasonic vortex fluid flowmeter (10) includes a housing (12) having a slip-on yoke (16) which removably mates with a bluff body conduit connector (18) permanently installed in a fluid conduit to be monitored. An ultrasonic transmitter (40) and receiver (42) are respectively positioned within the legs of the yoke so as pass an ultrasonic wave through vortices (43) shed by the fluid as it flows by the bluff body (28). The slip-on yoke eliminates both the need to shut down fluid flow during meter servicing, and the potential for external contaminants entering the fluid. The flowmeter further utilizes a simple phase detector formed from an Exclusive Or gate (44) in combination with an optimal phase range detecting means (108). The optimal phase range detecting means triggers a 90 degree phase shift whenever the phase difference between the transmitted wave and the received wave approaches 0 or 180 degrees. <IMAGE>

Abstract: PURPOSE:To make the production and assemblage of a rotation sensor easier so as to improve the reliability of the sensor by uniting a sensor housing housing a sensor element with a bearing cover to one body by resin molding. CONSTITUTION:After a pole piece 3, permanent magnet 4, and coil 5, constituting a sensor element, are assembled in a sensor housing 2 and lead wires 7 are connected, the mouth section of the housing 2 is sealed by filling up the mouth section with a thermosetting resin 9. Then the housing 2 is forcibly pushed into the guide section 8b of a bearing cover 8 by a prescribed length and, under such state where the housing 2 is forcibly pushed into and temporarily locked to the cover 8, the housing and cover 8 are united to each other by molding a thermoplastic resin 10. Since the sensor element section including the housing 2 and cover 8 are produced separately and finally united to each other by means of the resin 10 in such way, the producing process of this rotation sensor can be simplified. Moreover, since the housing 2 and mouth section of the cover 8 are sealed with the resin 10, water resistance, vibration resistance, etc., can be improved and the reliability can be secured effectively.
