More Information
Summary:An ultrasonic fluid measuring device capable of improving a measuring accuracy is provided. In an ultrasonic fluid measuring device 10, first to third ultrasonic measuring portions 16 to 18 are equipped with first ultrasonic transmitter-receivers 16A to 18A and second ultrasonic transmitter-receivers 16B to 18B provided to a measuring pass 14 respectively, and also first to third ultrasonic propagation paths 36 to 38 connecting the first ultrasonic transmitter-receiver 16A to 18A and the second ultrasonic transmitter-receivers 16B to 18B are provided to intersect with a passing direction of a fluid 24 flowing through the measuring pass 14 at different angles respectively. The ultrasonic fluid measuring device 10 employs any one of measured values of the first to third ultrasonic measuring portions 16 to 18 in response to a flow rate Q.
