The MR 500C series of dosing units is used for accurate dosing gas chlorine, sulphor dioxide and other gases in water supplies, waste water treatment plants and industry. The dosing capacity of M 520 is up to 15 kg/h, the MR 540C dosing capacity up to 40 kg/h and the dosing capacity of MR 550C is up to 200 kg/h. 
The device is built up as modular design in a self-standing cabinet unit with a casing made of glass fibre and can easily be adapted to any chlorination system. 
The MR 520C unit consists of a rotameter M 200 and also the vacuum and differential pressure regulator DP 20, gauge can be installed. 
The MR 540C unit consists of rotameter M 240 and also the vacuum gauge and differential pressure regulator DP 40 can be installed. 
The MR 550C unit consists of rotameter M 250 and also the vacuum gauge and a differential pressure regulator DP 50 can be installed.

The MR 520RRC system can consists of rotameter M 200, vacuum regulator M 20 ejector M 300, differential presure regulator DP 20, pressure gauge and vacuum gauge. 
The MR 540RRC system can consists of rotameter M 240, vacuum regulator M 40 ejector M 340, differential presure regulator DP 40, pressure gauge and vacuum gauge. 
The MR 550RRC system can consists of rotameter M 250, vacuum regulator M 50 ejector M 350, differential presure regulator DP 50, pressure gauge and vacuum gauge.
