超音波流量計
Document Type and Number:
Japanese Patent JP6546071
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ultrasonic flowmeter for measuring the flow rate of a fluid to be measured utilizing an ultrasonic wave, with which it is possible to suppress, between a front cover and a meter housing, the deformation of a control board held by a board holder due to an external force.SOLUTION: An ultrasonic flowmeter 1 causes an ultrasonic wave by a pair of ultrasonic transducers to propagate through a fuel gas flowing from an inflow port 11 toward an outflow port 12, and measures the flow rate of the fuel gas by a flow rate measurement unit 50 disposed inside a meter housing 10. Between the front of the meter housing 10 and a front cover 20 are disposed a control board 30 and a board holder 40 at positions apart by a prescribed dimension from the front of the meter housing 10. In the board holder 40, a support part 44 and a plurality of load bearing parts 45 are formed at positions rearward of a return switch 32 on the control board 30 held by a board holding part 41, subject to an operation load acting via the return switch 32 following the depression of a return button 22.SELECTED DRAWING: Figure 12
