Abstract: A two-way valve configured to switch between a communication state and a non-communication state of between a primary port and a secondary port includes a valve body having the primary port and the secondary port and containing a valve seat portion therein, a diaphragm valve supported inside the valve body so as to be brought into contact with and separated from the valve seat portion, and a drive mechanism configured to displace the diaphragm valve. The diaphragm valve includes an annular projection facing a flat seat surface of the valve seat portion and an elastic member attached at the back of the annular projection.

Abstract: An ultrasonic flow meter is equipped with a housing through which a liquid flows, and a pair of detection units disposed on opposite ends of the housing and including acoustic wave transmitting and receiving units capable of transmitting and receiving acoustic wave signals. Paired connecting plugs are connected respectively to both ends of the housing. In addition, a supply passage of one of the connecting plugs, a conduit of the housing, and a discharge passage of another of the connecting plugs are disposed on a straight line. A liquid supplied to the supply passage flows through a passage of the conduit and to the discharge passage. Consequently, a flow rate of the liquid is measured based on the propagation time of the acoustic wave signals, which are transmitted and received by the acoustic wave transmitting and receiving units.

Abstract: A pump system is equipped with a body, a displacement body, a bellows member, an indirect medium, and a diaphragm. The pump system is further equipped with a pressure sensor configured to detect a pressure of the indirect medium in a charge chamber, the charge chamber being formed to include an interior space of the bellows member in the interior of the body. A controller of the pump system determines an abnormality of the diaphragm based on detection values detected by the pressure sensor.

Abstract: An ultrasonic flow meter is equipped with a housing through which a liquid flows, and a pair of detection units disposed on opposite ends of the housing and including acoustic wave transmitting and receiving units capable of transmitting and receiving acoustic wave signals. Vibration generating mechanisms having vibration generating bodies arranged perpendicularly to the detection units are disposed on an outer circumferential side of the housing. In addition, when the flow rate of the liquid that flows through the housing is measured, the vibration generating bodies are energized and made to vibrate, such that gas bubbles, which adhere to cover members in contact with the liquid and that cover the acoustic wave transmitting and receiving units, are removed by the vibrations.

Abstract: A switching valve is constructed such that a rotor is rotatably provided inside a body and a cover member is provided with respect to the body so as to face a table part of the rotor. A gap having a prescribed interval is provided between an upper surface of the table part and the cover member, and a valve body biased toward the cover member side is provided to the table part. When rotating, the rotor does not slide on the bottom surface of the cover member, and leakage of a liquid from an inlet port is prevented due to the valve body seated on and closing an outlet port that is not the outlet port which is provided to the cover member so as to cause the liquid to be outputted therethrough.
