Abstract
The utility model relates to a photoelectric flow rate transducer which is mainly composed of a transducer body, a core body, an oil pipe joint, an impeller, a photoelectric transmitting tube, and a photoelectric receiving tube. When the measured medium passes through the transducer, the impeller is pushed to rotate, and the rotating speed and the flow speed are in the linear relationship in the prescribed flow rate range and under definite fluid viscosity. Thus, the electrical signal frequency generated through the photoelectric function is in direct proportion with the flow rate. The functions of the display of the instantaneous flow rate, the accumulation of the oil consumption, the memory storage, etc., can be completed by the function of a secondary instrument. The utility model has the advantages of advanced performance, and low cost. The utility model can proceed with the test of small flow rate, and the testing accuracy is high. The dynamic test can be realized in the airborne state.
