Due to the large number of combination possibilities of flow meters, twofold and threefold flow meters are
combined from: 2-3 single flow meters, mounting kit, mounting plate and mounting material. Please specify the
required measuring ranges when ordering.
The adjustment valves and the valve seats in the flow meter housing differ for each model / flow capacity. The
adjustment valves and the flow meter housings are marked respectively.

NOTICE!
If the chlorine gas flow is to be adjusted remotely in an automatic control system, a chlorine control valve is
integrated in the vacuum line between measuring glass and back-pressure regulator. If the chlorination instal-
lation is to correspond to the German standard DIN 19606, a back-pressure regulator must be used, which
avoids pressure fluctuations in the system. This back-pressure regulator is integrated in the non-return valve.
