【発明の名称】乱流の流れの計測及び表示指示のための装置及び流量応答指示計
Document Type and Number:
Japanese Patent JP2566802
Kind Code:
B2
Abstract:
In the measurement of fluid flow, the generation of a linearly varying signal and a pulsation free display are provided by a flow responsive indicator having digit displays (16, 18, 20, 22) for numerically indicating the rate of measured flow. The digit displays (16, 18, 20, 22) are driven in accordance with a measured flow signal applied to circuitry for generating an updated display signal from a previous display signal and the current value of the measured flow signal. This analog updated display signal is converted into a digital signal for driving circuitry connected to each of the digit displays. The measured flow signal applied to the indicator is generated at a flow transmitter including a transducer, such as a Hall effect element. This transducer generates a signal varying with flow in response to movement of a vane mounted in proximity thereto. To provide a signal varying linearly with flow rate, a flexible element extends into the fluid stream and by action thereof displaces the vane with reference to the transducer to generate the desired linearly varying signal.
