Dn80 Commercial Flow Meter , Positive Displacement Woltman Water Meter

Commercial flow meter for water utility billing, positive displacement Woltman water meter

Description

The dry dial water meters use the multi-jet principle, also single jet principle available for smaller port size. This vane wheel water meter is known for its wide range, simple operation, and accuracy in cold water or hot water totalization and flow rate metering. The impeller is centered in a ring of jets, with inlet jets on one level and outlet jets on another. A gear train drives the register totalizer dials. For pulse output, one of the dials is replaced by a gear, which turns a magnet that is detected by an encapsulated sensor threaded into the outside of the lens.

Pulse rate is determined by the gear and the dial on which the gear is placed. Changing the pulse rate requires no special tools and can be done in the field.
