Water Flow Meter 50-500mm

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.

Advantages

• The straight reading register operates in a dry compartment, which is under vacuum conditions. As a result the register always remains perfectly clear. Easy reading in any working conditions are ensured.
• Long operational life thanks to low rpm turbine and superior construction materials.
• A suitable shield protects the magnetic drive against any interferences from external fields.
• The hydraulic performance conforms to Class B of EEC standards.
• Meter is supplied complete with couplings and may be installed in the horizontal or vertical position
