Abstract
An ultrasonic flowmeter includes: a flow path body having a flow path through which a fluid to be measured flows; a pair of ultrasonic transducers disposed in the flow path body; a substrate fixed to the flow path body; a sensor plate on which a temperature sensor for detecting a temperature of the fluid to be measured is disposed, the sensor plate being flat; and an arithmetic unit that calculates a flow rate of the fluid to be measured from a propagation time of ultrasonic waves between the pair of ultrasonic transducers and the temperature detected by the temperature sensor. The sensor plate is configured to project from the substrate and to project into a flow path cross-section of the flow path from a sensor hole provided in the flow path body at a time of fixing the substrate to the flow path body.
