Abstract
An intelligent type elaborate dynamic metering instrument comprises three majorities which are a magnetic electricity converter or a photoelectric converter, a display and a metering bin. The mechanical kinetic energy generated by the medium measured flowing across the metering bin is transferred to the magnetic electricity converter or the photoelectric converter to induce out an electrical pulse signal corresponding to the flow quantity; the electrical pulse signals are processed by a circuit to display the results to realize dynamic metering of the fluid. The structure of the meter is simple, and the meter communicated with a microcomputer through the internet can realize automatic cluster control. The features of the meter lie in that high precision, strong intelligent performance and easy use and mounting. The meter is tested and qualified by the explosion-proof electric production quality supervising and detecting center. The meter is suitable for dynamically metering the places with explosive atmosphere danger.
