Dry Dial Woltman Water Meter DN300 Multijet Water Meter Vacuum Seal

Woltman dry dial water meter, impeller type for cold water flow rate and totalization DN300

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:

• Removable element structure, easy installation and maintenance, register for universal use within this
  range detachable without Removing the meter from the pipeline;
• Dry-dial, Magnetic drive sensitive action, small pressure loss;
• Vacuum sealed register ensures the dial keep free from fog and Keep the reading clear in a long
  term service;
  Selected high quality materials for steady & reliable characteristic;
• Technical data conform to international standard ISO 4064.

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%
