Description

A kind of high-precision ceramic lining electromagnetic flowmeter
Technical field
The utility model relates to flowmeter technology field, particularly relates to a kind of high-precision ceramic lining electromagnetic flowmeter.
Background technology
Electromagnetic flowmeter is the new type of flowmeter developed rapidly along with the development of electronic technology in the 50-60 age in 20th century.Electromagnetic flowmeter is application electromagnetic induction principle, is measured a kind of instrument of conductive fluid flow according to conductive fluid by the electromotive force of inducting during externally-applied magnetic field.Electromagnetic flowmeter by arranging magnetic field around conducting liquid, when conducting liquid is in magnetic field during cutting magnetic line, produce the induced potential be directly proportional to liquid mean flow rate, induced voltage signal is detected by the electrode of two or more and liquid comes into contact, after delivering to converter intelligent processing method, flow, the display of integrated flux and the communication between data on flows and microsystem and control when realizing liquid moment.
Current electromagnetic flowmeter is in non-full pipe liquid flow measurement, there is following problem: when the liquid level flowing through pipeline is not full of whole pipeline, the cross-sectional area of liquid is not equal to the cross-sectional area of pipeline, in non-full pipe, the height of liquid level may change at any time, now the cross-sectional area of liquid medium is Protean, and likely have larger fluctuation at any time, this all can cause electromagnetic flowmeter survey inaccurate.And be arranged on sudden and violent place of leaking due to electromagnetic flowmeter, through corroding for a long time, easily cause Housing failure, water is easy to enter and causes field coil and electrode cisco unity malfunction, thus cannot ensure that it is measured accurate.
Utility model content
The purpose of this utility model there is provided a kind of high-precision ceramic lining electromagnetic flowmeter, there is good long-time stability and accuracy, non-full pipe fluid flow can be measured accurately, can the entering of effective anti-sealing, thus prevented owing to leaking the impact caused measuring.
The technical solution adopted in the utility model is as follows:
A kind of high-precision ceramic lining electromagnetic flowmeter, comprise display control unit, convergence piece, shell, measuring guide, ceramic lined, field coil and electrode, described display control unit comprises display screen and converter, described display control unit is connected with shell by described convergence piece, in described shell, measuring guide is set, in measuring guide, ceramic lined is set, described measuring guide interior conduit xsect is provided with liquid level gauge, measuring guide is provided with field coil, field coil connecting electrode, protective seam is arranged with outside described field coil, sealant is arranged with outside described electrode.
Described display screen is LED backlit display.
Described protective seam is neoprene protective seam.
Described sealant is glazing compound sealant.
Compared with the prior art, the beneficial effects of the utility model are as follows:
(1) high-precision ceramic lining electromagnetic flowmeter of the present utility model, by arranging liquid level gauge at measuring guide interior conduit xsect, measure the liquid level of liquid medium, so just can obtain actual cross sections when liquid medium flows through flowmeter, and then record the actual flow value flowing through flowmeter, and then measure non-full pipe fluid flow accurately.
(2) high-precision ceramic lining electromagnetic flowmeter of the present utility model; by at the additional layer protective layer of field coil; and increase sealant in electrode part; improve the dielectric strength of field coil and electrode; even if having water to enter so also can not cause field coil and electrode cisco unity malfunction; field coil and electrode can be entered by effectively anti-sealing, thus prevent owing to leaking the impact caused measuring, the normal use of guaranteed flow meter and serviceable life.
(3) this practical ceramic lined utilizing sintering, improve rigidity and the physical strength of lining, there is good thermotolerance, wearing quality and corrosion resistance, electrical insulating property is high, not easily deform under high temperature, high pressure, be applicable to the fluid of high corrosion and grinding, can vacuum be tolerated, and insensitive for temperature variation, be applicable to the medium of acid, alkali, pastel, mud and other high burn into high solids contents.
