Abstract

1, 195,229. Measuring fluid-flow velocity. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 13, 1967 [Nov. 21, 1966], No. 52101/66. Heading G1A. In a method of measuring the velocity of a flowing stream of fluid by injecting a radioactive tracer into the fluid and measuring its transit time between two spaced points an inte - grating ratemeter is employed to determine the instants of transit. As described the fluid is water flowing through a conduit. A fluid pulse of a radio-active isotope in aqueous solution is injected into the water at a first point and the passage of this pulse is detected by geiger counters or scintillation detectors at two spaced downstream points. The pulse becomes asymmetric and spreads out as it progresses downstream and it becomes difficult to determine the mid point of the pulse as it passes the measuring points. By feeding the outputs of the geiger counters or scintillation detectors in integrating ratemeters controlling pen recorders each mid point is the point corres - ponding to half the amplitude change in the recorded curve due to the passage of the pulse. A backing off count may be applied to each ratemeter of compensate for background radiation.
