Abstract

The utility model discloses an electromagnetic flowmeter with a Teflon perforated electrode. The electromagnetic flowmeter comprises an electromagnetic flowmeter body and the Teflon perforated electrode, wherein the Teflon perforated electrode comprises a metal electrode which is connected with a thread rod, and Teflon is coated on the surface of the metal electrode. After the electromagnetic flowmeter with the Teflon perforated electrode is applied to the field of electromagnetic flowmeters, cement paste having the highest flow velocity of 18m/s can be measured, and the problem of noise interference produced while the cement paste rubs against the surface of the metal electrode is resolved. Measurement is more stable than that in past when the electromagnetic flowmeter measures solid-liquid two-phase bodies and cement paste media, measuring accuracy is high, and the noise interference of friction between the cement paste and the electrode is improved.

Description

A kind of electromagnetic flowmeter of teflon porous electrode
Technical field
The utility model relates to a kind of electromagnetic flowmeter of teflon porous electrode.
Background technology
The electromagnetic flowmeter that is using at present adopts 316l stainless steel or alloy electrode usually, kind electrode peak flow rate (PFR) when measuring grout can not surpass the 6m/s flow velocity, it is just undesired to show with output above the back instrument, mainly produces noise because of grout friction metal surface.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly can apply in the electromagnetic flowmeter, make electromagnetic flowmeter can survey the grout that peak flow rate (PFR) can reach 18m/s, and guarantee to measure stable and degree of accuracy, solve the teflon porous electrode of noise problem simultaneously.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of electromagnetic flowmeter of teflon porous electrode comprises that Electromagnetic Flow takes into account the teflon porous electrode, and described teflon porous electrode comprises a metal electrode, and described metal electrode is connected with threaded rod, and described surface of metal electrode scribbles the teflon material.
As optimized technical scheme, described teflon material adopts the mode of high temperature bond to be attached to surface of metal electrode.
As optimized technical scheme, described teflon material upper end is provided with micron-sized mesh, conducts electricity by mesh, picks up flow velocity signal, has effectively isolated the noise of grout.
The beneficial effect of the utility model teflon porous electrode is: make electromagnetic flowmeter can survey the grout that peak flow rate (PFR) reaches 18m/s after being applied to the utility model on the electromagnetic flowmeter, the noise problem that has been produced when having solved grout friction electrode metal surface simultaneously is more stable than measurement in the past when having solved electromagnetic flowmeter survey solid-liquid two-phase mixture and grout medium.The accuracy of measurement height has improved the noise of grout friction electrode.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of the utility model teflon porous electrode.
Embodiment
Consult the electromagnetic flowmeter of a kind of teflon porous electrode shown in Figure 1, comprise that Electromagnetic Flow takes into account the teflon porous electrode, described teflon porous electrode comprises a metal electrode 1, and described metal electrode 1 is connected with threaded rod 2, and described metal electrode 1 surface scribbles teflon material 3.
Wherein, described teflon material adopts the mode of high temperature bond to be attached to surface of metal electrode.
Described teflon material 3 upper ends are provided with micron-sized mesh.
The utility model is to pass through pyroprocessing on metal electrode 1 surface, makes teflon material and metal surface better bonding.When coating for metal surfaces, the teflon material made have micron-sized hole and conduct electricity with mesh, pick up flow velocity signal, effectively isolated the noise of grout.
The beneficial effect of the utility model teflon porous electrode is: make electromagnetic flowmeter can survey the grout that peak flow rate (PFR) reaches 18m/s after being applied to the utility model on the electromagnetic flowmeter, and measure stable, the degree of accuracy height, the noise problem that has been produced when having solved grout friction electrode metal surface simultaneously.
The above only is an embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
