A full bore, helix Woltmann type water flow meter suitable for cold water with interchangeable mechanism-dry dial. The impeller which is of modern design, rotates on stainless spindles mounted in the measuring chamber.
The impeller is made of self-cleaning synthetic resin. The helix aligns with the pipe axis. The complete metering unit is easily removable from the meter body and is designed to ensure high flow-rate with the minimum headloss.
The gears and the totaliser operate under vacuum in a dry compartment, only the helix is submerged in the water. The transition is achieved through a corrosion-proof permanent magnetic drive which is protected by the cast iron meter body from from external magnetic forces.
Versions available for both cold (30°C) or hot (90°C) water complete with pulse output.
