In the food and beverage industry, juice, milk, and hops must be mixed, added, and filled under hygienic conditions. In the chemical and paper industries, our equipment processes acids, alkalis, pastes, sludge, and other corrosive media, while in non-ferrous metals and mining, high solid content media (such as slurry) wash Cologne's instruments every day.

The vortex flowmeter is suitable for measuring various media, which is the true side of the Cologne OPTISWRL *:
It can measure conductive and non-conductive liquids as well as all industrial gases. It can also measure saturated steam and superheated steam, compressed air and nitrogen, liquefied gas and flue gas, softened water, boiler feedwater, solvents, and heat transfer oil.
Thanks to integrated pressure and temperature compensation, the OPTISWRL 4070 is even suitable for working conditions with pressure and temperature fluctuations.
