Optimarin uses M910Es in Ballast Water Systems (BWS) for large cargo vessels. These systems are used to purify ship's ballast water before discharging it which prevents spread of idigenous organisms to local marine environment.

M910E's maintenance free, robust design and high accuracy at reasonable price are ideal for this application. And the list of reasons why Meatest is the sole supplier of flow meters to Optimarin does not end in production:

"Optimarin is very happy with the flowmeters from Meatest. Very few issues and very quick response on support."
