Abstract: PURPOSE:To obtain a method and device for measurement with which a calibration value and a correction value can be obtained while a dissolved oxygen electrode is kept immersed in an aeration tank by determining the calibration value corresponding to the change in the characteristic of said electrode and the correction value corresponding to the consumption of the dissolved oxygen by the filth sticking and depositing on the inside wall of a measuring vessel thereby enabling the exact measurement of the velocity in using oxygen. CONSTITUTION:The inside of a measuring vessel 21 for aeration is filled positively with a calibrating liquid, and while the calibrating liquid is kept stirred with a rotor 10 by driving a stirrer 9, air is supplied through an air supply port 11 for aeration so that the calibrating liquid in the vessel 21 is aerated until the liquid attains the satd. concn. of the dissolved oxygen. The calibrating liquid having the satd. concn. of the dissolved oxygen is measured with a dissolved oxygen electrode 3 and a dissolved oxygen measuring device 4. On the other hand, the water temp. of the calibrating liquid is measured by a temp. sensor 28 and a temp. measuring device 29. The concn. of the satd. dissolved oxygen changes with the water temp. and the value thereof is known. The known satd. concn. of the dissolved oxygen is thus determined from the water temp. of the calibrating liquid. The difference between the known satd. concn. of the dissolved oxygen and the value actually measured with the device 4 is the contamination of the electrode 3 and the change in the characteristic intrinsic to the electrode with time.

Title: Pump device
Inventor: INAGUMA YOSHIHARU
IPC: F04C14/26
Filed: 1985-08-08
Abstract: PURPOSE:To enable reduction of production of pulsation, vibration, and noise, by a method wherein a suction passage is installed parallel to a bypass hole and eccentrically in a direction opposite to the moving direction of a valve spool, and working fluid in the suction passage is caused to flow about along a central axis thereof. CONSTITUTION:The direction of a jet J of working fluid injected when a flow rate regulating valve 30 is opened extends at an acute angle with a moving direction X of a valve spool 32 adapted to open a bypass hole 12 through the influence of a flow within the valve 30. However, since the bypass hole 12 is also formed in a manner to be inclined toward the direction, and since an effect of adhesion to the inner wall of the bypass hole 12 is produced, a jet J of the working fluid flows along the inner wall, opposite to the moving direction X, of the bypass hole 12 and flows in a suction passage 11. Since the suction passage 11 is formed parallel to the bypass hole 12 and eccentrically in a direction opposite to the moving direction X of the valve spool 32, the jet J flows about along a central axis 02 of the suction passage 11 togetherwith the working fluid fed through a fluid feed passage 14 and is sucked in a pump 20, and this reduces production of pulsation, noise, and vibration.
