METHOD OF AUTOMATIC MEASUREMENT OF MASS FLOW OF LIQUIDS OR GASES AND A DEVICE FOR ITS ACCOMPLISHMENT,
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO
The distinguishing peculiarity of the proposed method of automatic checking of mass-flow ratio or a liquid or a gas is the fact that the mass-flow ratio is determined in accordance with the magnitude functionally depending on the mass-flow ration, i. e., the magnitude of the torsional moment on an element elastically connected with the rotor of the turbo-machine which gives to the flow an angular velocity. This increases the dependability and lowers the figure for the required energy. The proposed device is distinguished from others by combining the operating and measuring function in one unit. The vane wheel with lengthwise channels is united by an elastic element with the operating wheel and on the body of the turbo-machine there are mounted magneto-induction pickups, which convert the size of the angle of the lagging of the vane wheel behind the operating wheel into electrical impulses. In accordance with the time interval between these impulses one determines the mass-flow ratio.
