Compact volume corrector EC 900

The EC 900 compact volume corrector is preferably suitable for use in small to medium-sized measuring systems in which measurement is carried out with rotary displacement meters or turbine meters and where there is no electrical room with control cabinets. Such systems are often found when they are handed over to small municipal utilities or commercial gas customers.
