Impeller Type DN25 Multi Jet Water Meters / Single Jet Water Meter With Pulse Output

Single jet impeller type water meter for hot water volume measure port DN25 brass

 

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.

 

Feature:

  • Single-jet, dry-dial, free rotating register, small in size and light in weight;
  • Magnetic drive, Resistance to exterior magnet interference,
  • keep the reading clear in a long term service;

Note:

  • Measuring accuracy conform to ISO 4064 class B standard..
  • Available with different length on request. Available in hot water meter on request.

Working condition:

  • Water temperature:0.1℃~40℃( 0.1℃~90℃ for hot water meter)
  • Water pressure: ≤1.0Mpa

Maximum Permissible Error:

(1) in the lower zone from qmin inclusive up to but excluding qt is ±5%

(2) in the upper zone from qt inclusive up to and including qs is ±2%

(3) Hot water meter ±3%
