Abstract
The utility model discloses an electrode for an electromagnetic flow meter. The electrode comprises a T-shaped electrode body. The electrode is characterized in that the T-shaped electrode is composed of a T-shaped structural body and a protective film layer. The protective film layer completely covers a liquid receiving face on the T-shaped structural body. The electrode for the electromagnetic flow meter has the advantages of being capable of reducing a use amount of corrosion-resistant metal materials and capable of reducing cost of the electrode in the electromagnetic flow meter.
Description
Technical field
The utility model relates to a kind of liquid flow measurement device, relates in particular to a kind of electrode for electromagnetic flowmeter and electromagnetic flowmeter.
Background technology
The principle of electromagnetic flowmeter is: conductive liquid flows in perpendicular to the non magnetic measuring tube in magnetic field, can produce and the proportional induced potential of flow on the direction vertical with fluid flow direction, according to Faraday's electromagnetic induction law, just can know the flow size that flows through as long as can measure the size of induction electromotive force.
In commercial production, often need measure the flow of corrosive liquids, the medium that electrode material on the electromagnetic flowmeter must and be measured adapts, could guarantee like this electrode not very soon being corroded property medium corrode, thereby make electromagnetic flowmeter can carry out signals collecting for a long time, normally; Problems of the prior art are: electrode is whole usually to adopt corrosion resistant metal material to make, and corrosion resistant metal material general cost is higher, and the surface area relative less (than total surface area of electrode) in the zone that contacts with corrosive liquids on the electrode, this just causes the cost performance of electrode relatively low, especially in some in the sensor of small dimension, the cost of electrode might be more taller than the summation of other parts costs.
The utility model content
At the problem in the background technology; the utility model proposes a kind of electrode for electromagnetic flowmeter; comprise T shape electrode, its improvement is: described T shape electrode is made up of T shape structure and protective film, and described protective film all covers the liquid level that connects on the T shape structure.
After adopting the electrode of aforementioned structure; because the protected rete of liquid level that connects on the T shape structure wraps up; then T shape structure does not need to contact with fluid to be measured; need not consider the corrosion-resistant problem of T shape structure fully; therefore; T shape structure on the T shape electrode and protective film can adopt the metal material of unlike material to make respectively; wherein; T shape structure can adopt metal material making cheaply; protective film can adopt the higher relatively corrosion-resistant metal materials of cost to make; thereby reduce the consumption of expensive corrosion-resistant metal materials greatly, improve the cost performance of electrode, reduce production costs.
Based on aforementioned schemes, the utility model has also proposed following material preferred version: described T shape structure adopts stainless steel material to make; Described protective film adopts the platinum material to make.
For T shape structure is played the better protection effect, the utility model has also been done following improvement: the medial surface that connects liquid level place structure on the described T shape structure forms sealing surface, and described protective film extends to sealing surface and sealing surface is all covered.
With the making of the electrode in the aforementioned schemes for electromagnetic flowmeter, similarly, the production cost of electromagnetic flowmeter also is reduced.
Useful technique effect of the present utility model is: can reduce the consumption of corrosion-resistant metal materials, reduce the electrode cost in the electromagnetic flowmeter.
