Abstract

PURPOSE:To make it possible to take measurements of high sensitivity with accuracy without exerting any influence of the viscosity coefficient of a fluid by detecting the position of a piston set in motion by being pushed by the fluid by a contactless sensor in a cyclinder. CONSTITUTION:When the 1st change-over valve 4 and the 2nd change-over valve 10 are changed over as shown in the figure in the measurement of the flow rate of oil pump1, the discharge of pump 1 is supplied to one chamber 11a of cylinder 13 and a minute difference in pressure between chamber 11a and the other chamber 12a is generated, so that piston 14 will move until the difference in pressure disappears. Through brass foil 15, an extremely-lightweight conductor, stuck to piston 14, the moved quantity is detected by contactless sensor 16 as a voltage proportional to the moved quantity.
