Problems solved by technology

[0005] The application of electromagnetic flowmeter has certain limitations. It can only measure the liquid flow of conductive medium, and cannot measure the flow of non-conductive medium.
The installation and commissioning of electromagnetic flowmeters are more complicated than other flowmeters, and the requirements are stricter
The transmitter and converter must be used together, and two different types of instruments cannot be used between the two

Abstract

The invention discloses a novel impeller electromagnetic flowmeter. The novel impeller electromagnetic flowmeter comprises a pipeline, an impeller, a coil, a supporting frame, a magnet assembly and anelectrical measuring instrument; the supporting frame comprises a shell and at least one support part; the support parts are connected to the outer wall of the shell; the supporting frame is locatedin the pipeline, and the support parts of the supporting frame are connected with the inner wall of the pipeline; the impeller comprises an impeller body and a plurality of blades; the blades are evenly distributed on the outer wall of the impeller body; the opening end of the impeller body is rotatably connected into the opening end of the shell; the coil is installed in the impeller body, a wireof the coil penetrates into the shell; the magnet assembly comprises a magnet I and a magnet II; the magnet I and the magnet II are symmetrically arranged on the outer wall of the pipeline; and the coil is located between the magnet I and the magnet II; the electric measuring instrument is electrically connected with the coil, and the electric measuring instrument measures the induced electromotive force frequency of the coil. The ovel impeller electromagnetic flowmeter is compact in structure, low in installation and debugging and maintenance costs, does not require too detailed operation compared with other flowmeters and is excellent in calibration performance.

Description

Technical field [0001] The invention belongs to the field of fluid measurement, and specifically relates to a novel impeller electromagnetic flowmeter. Background technique [0002] At present, in all fields of chemical industry, energy, water conservancy, etc., the measurement and control of fluids are very important. For this reason, many fluid measurement devices have been born. Today, when the process requirements are becoming more and more stringent, it is necessary to master the relevant pipeline flow parameters to operate the equipment. , Scientific experiments, and system maintenance are very important. [0003] The existing measuring flow meters mainly include electromagnetic flow meters, ultrasonic flow meters, vortex flow meters, orifice flow meters, elbow flow meters and so on. However, as a whole, these measuring devices have high accuracy and high cost, low-cost operations are complicated, and simple operations have insufficient accuracy. [0004] See Figure 13 , For ...
