摘要： In an ultrasonic flow meter device of the present invention, a compressive conductive fastener member including conductive parts is retained between a casing having a fluid passage in which a fluid which is a measurement target flows; ultrasonic transmitters/receivers mounted to the casing, and a control printed board disposed to face the ultrasonic transmitters/receivers, and in this state, the control printed board is fastened. Thereby, the ultrasonic transmitters/receivers are electrically connected to the control printed board without the use of lead wires. A cost increase can be suppressed, and an influence of an outside noise can be mitigated because of omission of the lead wires. Therefore, reliability of the ultrasonic transmitters/receivers can be improved.

摘要： Ultrasonic transducers are attached in a direction of compressing O-ring provided in a housing with a flow passage. Biasing means makes contact with and presses these ultrasonic transducers and at multiple points. A screw is provided for locking this pressing means to the housing. This enables the use of O-ring as a sealing means. Accordingly, an in-expensive ultrasonic flowmeter that facilitates signal processing by reducing propagation of vibration of the ultrasonic transducer to the housing can be achieved.
