Promatik - Model NG -Domestic Water Metering System

Protects pipework, fittings, and appliances from corrosion and limescale.

In a flow of water, the contact water meter transmits pulses with a fixed pulse interval corresponding to the pulses to the metering pump in line with the flow. Each of these pulses results in a metering stroke of the metering pump, thereby feeding the metering solution. The metering volume per stroke can thus be adjusted continuously between 100 and 50% using the stroke adjustment dial. Because of the very low starting limit and short pulse interval, a constant volume-proportional addition of chemicals can always be maintained from minimum water flow rate to maximum load, thereby guaranteeing the best process result.

• DVGW-tested in conjunction with the EXACTAPHOS metering solution. DVGW No. NW-9101 CM 0179.
• The EXACTAPHOS metering solutions are matched to the capacity of the Promatik metering systems.
• Fitting position of the water meter – horizontal and vertical.

• Consisting of a Beta metering pump, contact water meter, suction assembly with foot valve and 2-phase level switch with pre-warning as low flow contact and empty signal, injection valve and metering line.
• In the "R" design compact metering system, the metering pump is built onto the contact water meter.
• In the "W" design split system there are wall brackets for accommodating the metering pump. Contact cable and PE metering line 2 m long. Horizontal fitting position of the contact water meter.
