The optional electrode of electromagnetic flowmeter

The choose and buy of electrode of electromagnetism flowmeter, how to choose the material of lining accurately.The lining material should be selected according to the corrosivity, abrasion and temperature of the material being measured.

1. Rubber.It has excellent elasticity, high tearing force, good wear resistance, and is resistant to the erosion of weak acid and alkali. It can measure water, sewage, sand and coal slurry, etc.

2. Polyurethane.It has excellent abrasion resistance, poor acid and alkali resistance, and can measure the coal slurry, sand slurry and coal slurry with strong neutral wear.

3. Polytetrafluoroethylene.Resistance to boiling sulfuric acid, sulfuric acid, sodium cyanide, aqua, concentrated alkali and various solvents, wear resistance, adhesion function is weak.

The earthing ring of the electromagnetic flowmeter is connected at both ends of the air flowmeter of the plastic pipe or the metal pipe lined with insulation. Their corrosion resistance is lower than that of the electrical level.Acid - resistant steels or harrods are usually used.Because of the large volume from the economic development of the use of rare metals such as tantalum platinum.If the metal process pipe is in direct contact with the fluid, an earthing ring is not required.

With the development of the society, various industries pay more and more attention to the automation process control. Seeing the turning point of the instrument industry, MrStone resolutely resigned as a senior engineer of Siemens, inherited the family business, and left his hometown to set up Shanghai porcelain xi instrument co., LTD.Specializing in the production and development of high precision, wide range of flowmeters.The output equipment all USES the Siemens numerical control machining center, the cutting precision is up to 0.001mm, the production process strictly implements the ISO9001 standard, lets you be able to buy the German quality flowmeter in China.
