Selection of electrode material
Materials of electrode	Corrosion resistance
Mo-containing stainless steel (0Cr18Ni12Mo2Ti)	Able to work with medium with weak corrosivity, such as industrial water, living water, polluted water, etc., widely used in industries like oil, chemical, urea, vinylon, etc..
Stainless steel-coated wolfram carbide	Used for medium without corrosivity or with weak wear ability.
Hastelloy B(HB)	Good corrosion resistance of different concentration of hydrochloric acid under boiling point, resist the corrosion of non-oxidizing acid, alkali, non-oxidizing salt solution, such as sulfuric acid, phosphoric acid, organic acid, etc..
Hastelloy C(HC)	Resist the corrosion of oxidizing acid, such as nitric acid, mixed acid, the mixture of chromic acid and sulfuric acid, oxidizing salt like Fe+++, Cu++ or other oxidants such as hypochlorite solution above ordinary temperature and seawater.
Titanium(Ti)	Resist the corrosion of seawater, all kinds of chloride, hypochlorite, oxidizing acid(include fuming nitric acid), organic acid, alkali, etc., unable to resist the corrosion of purer reducing acid like sulfuric acid and hydrochloric acid. The corrosivity of alpha hydroxy acids will be substantially decreased if there are oxidants such as nitric acid, Fe+++, Cu++ , etc. in it.
Tantalum(Ta)	The corrosion resistance of tantalum is as good as glass. Except hydrofluoric acid, fuming nitric acid and alkali, it is able to resist the corrosion of almost any other chemical media.
Platinum-iridium alloy(Pt)	Almost be able to work with any chemical medium other than aqua regia and ammonium salt.

Company Information  Company information-------remote flow meter              •We have been in this business for more than ten years.           •Our customer satisfaction is 99.5%.           • We are located in Kaifeng, the most ancient and biggest base of flow instrument in China, which means we have full access to the most advanced technologies in this field.           •We are awarded ISO9001:2008.           •Our belief is "Accuracy and Attitude ,Access to Customer".           •We are able to provide electromagnetic flow meters with international stanards.           •Our goal is to make world wide brand. Our Services Selection of nominal diameter-------remote flow meter 1.As electromagnetic flowmeter has a high rangeability of 1500:1, the selection of nominal diameter is the same as that of process pipe; 2.If there are solid particle in the measured medium, a flow rate range of 1~3m/s is recommended, If the practical flow rate is excessive yet inconvenient to adjust, the nominal diameter of the instrument is better larger than that of the process pipe, under which condition the flow rate in the measuring pipe of the flowmeter can be properly decreased and the abrasion of electrode and liner caused by the particle can be alleviated; 3.If there are sediment in the process pipe, a flow rate range of 2~5m/s is recommended. If the practical flow rate is too little, the nominal diameter of the instrument is better smaller than that of the process pipe in order to properly increase the flow rate of the fluid in the flowmeter to avoid the effect on the accuracy caused by the sediment. 4.If the flow rate is too little yet a high-precision measurement is required, a sensor smaller than the nominal diameter can increase the flow rate to ensure high precision.      In the above 2,3,4 conditions, a reducing pipe should be jointed to both the upstream and downstream of the flowmeter. The center taper angle should be no more than 15and there should be a straight pipe at least 5 times of the process pipe jointed to the reducing pipe.
