    • There is provided a method and device for producing an absolute pressure type pressure sensor that enables a relative pressure type pressure sensor to be modified (converted) into an absolute pressure type pressure sensor in a simple and easy manner. The method is characterized by comprising: a step of arranging a relative pressure type pressure sensor, that has a reference pressure chamber therein, and a pressure guide hole whose one end communicates with the reference pressure chamber and the other end opens to the atmosphere, inside a vacuum chamber with the other end of the pressure guide hole opening upward; a step of placing a solder piece onto the other end of the pressure guide hole; a step of drawing a vacuum inside the vacuum chamber; and a step of heating the solder piece until the solder melts.

    • The ultrasonic flow meter of the present invention comprising a measuring pipe through which liquid flows, and two measuring units provided at an interval in the lengthwise direction on measuring pipe. A tightly adhered tube having elasticity is attached to an attaching indentation formed in the measuring pipe over the peripheral direction, and its inner peripheral surface is tightly adhered to the outer peripheral surface of measuring pipe. A transducer is arranged on the outer peripheral surface of tightly adhered tube in the state in which it is pressed against the outer peripheral surface of the tightly adhered tube. In this ultrasonic flow meter, the transmission of vibrations between the transducer and fluid inside the measuring pipe can be carried out uniformly.
    • 本发明的超声波流量计包括液体流过的测量管和在测量管上沿长度方向间隔设置的两个测量单元。 将具有弹性的紧密粘合的管附接到在测量管上形成的在周向上的安装凹部,并且其内周面紧密地粘附在测量管的外周面上。 传感器在紧贴在紧密粘合的管的外周表面的状态下布置在紧密粘合的管的外周表面上。 在这种超声波流量计中,传感器与测量管内的流体之间的振动传输可以均匀地进行。
