    摘要： In regulating a burning gas quantity of a gas combustion apparatus, a gas flow controller is used. The gas flow controller is constructed such that a closing member within a cock is rotated by using a motor. The closing member has a plurality of holes formed in the axial direction of the member and a plurality of grooves each corresponding to the hole and formed in the circumferential direction of the member. The cock is used for changing, opening and closing a plurality of orifice passageways. The motor is driven in accordance with a signal from a position determining unit which discriminates the position of the cock. The gas flow controller can advantageously ensure a high precision of gas flow, a high reduction ratio, and a low power consumption.

    摘要： An ultrasonic fluid measurement instrument is capable of highly accurate fluid measurement. A measurement part is provided forming a plurality of split channels partitioned by partition boards halfway across a fluid channel, and at least a pair of ultrasonic transmitter-receivers for transmitting ultrasonic waves into the fluid flowing through the split channels and receiving ultrasonic waves that have passed through the fluid. Further, an arithmetic unit calculates the flow velocity and/or flow volume of the fluid according to the propagation time of the ultrasonic waves. The measurement part further includes an approach channel for preliminarily rectifying the fluid flowing to the split channels.
