Embodiment 1

[0017] like figure 1 As shown, an electromagnetic flowmeter includes a controller, a flow detection module is connected to the input end of the controller, a power detection module and a flow direction detection module are also connected to the input end of the controller, and the controller The output terminal is also connected with liquid crystal display, serial port communication and alarm output.

[0018] In this embodiment, since the flow determination principle of the electromagnetic flowmeter is based on Faraday's law of electromagnetic induction, that is, the variable is the change of the average flow velocity in the pipeline section when the fluid flow in the pipeline changes, this makes the existing electromagnetic flowmeter compared with the traditional mechanical The flow meter form has a more complicated circuit structure. The set power supply detection module is used to monitor the power supply state of the system, the set flow direction detection module is used...

Embodiment 2

[0020] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, in order to enable the present invention to have a temporary storage function for historical data, a memory is also connected to the controller.

[0021] As a structural form or connection relationship that can store the setting program or parameters of the present invention, the memory is bidirectionally connected to the controller.

[0022] In order to facilitate the control of the magnetic induction intensity of the magnetic field according to the specific application field, an excitation voltage output module is also connected to the output end of the controller.

[0023] In order to further optimize the functions of the present invention and reflect the change of the fluid flow in the pipeline more comprehensively, a flow frequency output module is also connected to the output end of the controller.

[0024] As a well-compatible serial communication setting method, the se...

Abstract

The invention discloses an electromagnetic flow meter. The electromagnetic flow meter includes a controller; an input end of the controller is connected to a flow detection module; an input end of the controller is connected to a power source detection module and a flow direction detection module; an output end of the controller is connected to a liquid crystal display, a serial port communication unit, and an alarm output unit. The electromagnetic flow meter system can enrich the functions of the electromagnetic flow meter, integration of all the functional parts or auxiliary modules of the electromagnetic flow meter can be achieved by using the conventional popular single chip microcomputers having excellent performance, and design, selection and installation of a flow system of a user is facilitated.

Description

technical field [0001] The invention relates to the field of fluid conveying pipe fittings, in particular to an electromagnetic flowmeter. Background technique [0002] Electronic metering equipment is widely used in fluid delivery pipeline systems. Compared with mechanical metering equipment, it can facilitate remote transmission, small size, easy equipment maintenance, and can be installed and debugged outside the pipeline during the use of the pipeline. , It is widely used in people's daily life and industrial production: such as urban tap water, natural gas pipeline network system; industrial fluid transmission pipeline system, etc. The function of the existing electromagnetic flowmeter is limited to passively accept the flow signal from the converter. In some fields that require high detection or control accuracy, more functional modules are often required to monitor the fluid flow. . The above defects make users need more professional personnel to carry out system de...
