Single jet dry dial water meter for cold water volume measure port DN15 cast iron
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.
