Disclosed is an ultrasonic Doppler flow measurment system that achieves flow measurement regardless of the temperature of a fluid. A temperature sensoris combined with a pipeto measure the temperature of a fluidA controllercalculates a frequency that will cause cavitation when an ultrasonic transducerexerts an ultrasonic vibration on the fluidon the basis of a temperature measured by the temperature sensorand controls a sinusoidal oscillator

Ultrasonic cavitating apparatus and ultrasonic doppler flow measurement system

A bubble generator to bring out performance of a Doppler ultrasonic flowmeter to the maximum extent is provided. The bubble generator is provided with a bubble generation member generating bubbles suitable for a predetermined frequency of an ultrasonic pulse emitted into a fluid to be measured and feeding the bubbles into the fluid pipe, and a uniform dispersion member dispersing the bubbles fed uniformly in the pipe, the bubble generator is installed on an upstream side of the fluid pipe with respect to an ultrasonic transducer. The bubble generation member has a Venturi tube, and the uniform dispersion member has a negative pressure generating device, in which the fluid to be measured drawn out by the uniform dispersion member from inside the fluid pipe is returned into the fluid pipe together with the bubbles fed into the fluid pipe via the Venturi tube.

Bubble generator for use in doppler ultrasonic flowmeter and doppler ultrasonic flowmeter

A token purchasing device that can automatically change the number of tokens purchased for a given price based on time, date, and day of the week information. The token purchasing device includes a banknote accepting unit for accepting a banknote and outputting a banknote value signal based on the denomination of the accepted banknote, a clock unit for outputting the current time and date information, a control unit for computing the number of tokens for dispensing, and a token dispensing unit. The control unit is configured to store a predetermined set of days or a range of times from a start time to an end time defining a special purchasing mode. The control unit can automatically change the number of tokens purchased when the current time and date is within the programmed parameters for the special purchasing mode.
