Summary of the invention
More professional personnel are needed when suitable electronic formula metering outfit to carry out system for above-mentioned user, in follow-up use procedure safeguard and debugging difficulty large, be unfavorable for the problem of the popularization of electronic type metering outfit in productive life field, the invention provides a kind of electromagnetic flowmeter.
For the problems referred to above, a kind of electromagnetic flowmeter provided by the invention reaches goal of the invention by following technical essential: a kind of electromagnetic flowmeter, comprise controller, the input end of described controller is connected with flow detection module, the input end of described controller is also connected with power detecting module and flow detection module, the output terminal of described controller is also connected with liquid crystal display, serial communication and warning and exports.
Concrete, because the flow resolution principle of electromagnetic flowmeter is based on Faraday's electromagnetic induction law, namely mean flow rate change when variable is fluid flow change in pipeline in pipeline section, this just makes existing electromagnetic flowmeter have more complicated circuit structure compared to traditional mechanical flowmeter form.The power detecting module arranged is used for the power supply state of monitoring system; the flow detection module arranged is for judging the flow direction of fluid, and the liquid crystal display of setting, serial communication and warning export the warning being respectively used to the showing of state parameter of the present invention, the remote transmission of state parameter and control signal input, check result exception or system exception on the spot.Electromagnetic Flow meter systems provided by the invention is conducive to the function enriching electromagnetic flowmeter, to utilize existing single-chip microcomputer that is universal and excellent performance to form the integration of each functional part of electromagnetic flowmeter or supplementary module, be convenient to the flow system design of user, type selecting and installation etc.
Further technical scheme is:
For making the present invention, there is historical data and keep in function, described controller is also connected with storer.
As a kind of version or the annexation that store setting program of the present invention or parameter, described storer and controller are bi-directionally connected.
For ease of the magnetic induction density according to concrete utilization field controlling magnetic field, the output terminal of described controller is also connected with field voltage output module.
For optimizing function of the present invention further, can the situation of change of fluid flow in reacting pipe more comprehensively, the output terminal of described controller is also connected with traffic frequency output module.
As the serial communication set-up mode that a kind of compatibility is good, described serial communication is RS485 interface.
The present invention has following beneficial effect:
Structure of the present invention is simple; the power detecting module arranged is used for the power supply state of monitoring system; the flow detection module arranged is for judging the flow direction of fluid, and the liquid crystal display of setting, serial communication and warning export the warning being respectively used to the showing of state parameter of the present invention, the remote transmission of state parameter and control signal input, check result exception or system exception on the spot.Electromagnetic Flow meter systems provided by the invention is conducive to the function enriching electromagnetic flowmeter, to utilize existing single-chip microcomputer that is universal and excellent performance to form the integration of each functional part of electromagnetic flowmeter or supplementary module, be convenient to the flow system design of user, type selecting and installation etc.
