Abstract: PURPOSE: An installation jig for an ultrasonic flow sensor is provided to easily install an ultrasonic sensor at an optimal position on an exterior surface of a pipe with consideration for a dispersing angle when measuring a flow rate. CONSTITUTION: An installation jig for an ultrasonic flow sensor comprises a sensor mounting unit(20), a jig body unit(10), and a moving unit(30). The ultrasonic flow sensor is mounted in the sensor mounting unit. The jig body unit fixes the sensor mounting unit and is joined to the outer periphery of a pipe. The moving unit is formed in one side of the jig body unit, thereby moving along the outer periphery of the pipe.

Abstract: PURPOSE: A method for detecting Doppler signals measured by an LDA(Laser Doppler Anemometry) is provided to measure the velocity of fluid using high quality Doppler signals. CONSTITUTION: A reference level for detecting Doppler signals for the fluid velocity measurement is set up among Doppler signals measured from an LDA(S100). The Doppler signal measured from the LDA is not dimensioned(S200). A candidate group to satisfy the reference level among the Doppler signals which are not dimensioned is detected(S300). The Doppler signal to satisfy the reference level based on the detected candidate group is detected, and whether the detected Doppler signal is suitable for fluid velocity measurement or not is verified(S400).

Abstract: PURPOSE: An apparatus for correcting micro particle image velocimetry is provided to improve the precision of correction by controlling the number of times that a rotational plate rotates and displaying an A-type uncertainty about the movement of the rotational plate and a B-type uncertainty about a distance between camera pixels. CONSTITUTION: A micro particle image velocimetry correcting apparatus(10) comprises a rotational plate(20), a frequency counter(40), a microscope(50), a micro-PIV(Particle Image Velocimetry)(60), and a PC(70). The rotational plate is rotated by a motor(30). A frequency counter measures the rotation speed of the motor. The microscope is arranged near the rotational plate. The Micro-PIV is arranged in the microscope. A PC receives a frequency counter signal and an image which is obtained in the micro-PIV and performs velocity correction.

Abstract: PURPOSE: Clustered pipelines for correction and a device for testing and correcting a blood flow meter using the same are provided to measure a blood flow value by correcting the blood flow meter after the correction value of an ultrasonic blood flow meter is calculated. CONSTITUTION: A clustered pipeline body(1) has a blood path with different diameters. Two covers(2,3) are installed on both sides of clustered pipelines. An inlet(21) and an outlet(31) connected to one blood path are installed in two covers. A support(4,5) supports the cover and closely contacts the cover with the clustered pipeline body. A body insertion groove(3a) with the same diameter as the outer diameter of the clustered pipeline body is formed on the surface facing the clustered pipeline body of the covers.
