We have no sea, but we know how to measure salt water

Salt or seawater contains chemicals that cause different physical and chemical properties in comparison to fresh water. The salinity of seawater has an influence on density, on the different temperatures of freezing and mainly on the corrosion of any constructed object with which it may come into contact.  

ElisFlonetThe average salinity of seawater is around 3.5%. This means that each kilogram of seawater contains approximately 35g of dissolved salts, making seawater highly corrosive.  Not only does it dissolve the metal ions of different alloys rapidly, seawater also has a negative effect on many other materials used in the manufacture of devices for measuring the of flow of seawater.

It is, therefore, critically important to choose suitable materials for sensor linings as well as the electrodes of induction flow meters used for continuous measurement of seawater.  This ensures not only that the durability, longevity and functionality is optimal, but economical too.

Instrotech has recently signed-up a new agency, ELIS PLZEN, Czech Republic manufacturer and supplier of FLONET induction flow meters in different dimensions (DN20-DN800), suitable for saline applications.  It may be a land-locked country, but that has not deterred ELIS PLZEN dedicating many years of R&D test experience with applications for seawater, to ensure their induction flow meter’s reliability and durability.   

ELIS PLZEN’s induction flow meters for saline application have sparked interest in the market, and particularly their FLONET model DN700, which was recently dispatched within 3 weeks of order to a client in Greece.
