Plastic R80 Dry Dial Water Meter Class B Multi Jet Accurate Measuring

Plastic Residential Smart Water Meter, multi jet water meter, ISO4064 Class B, R80

General 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.

Feature:

• Multi-jet, dry-dial, easy for maintenance;
• Magnetic drive reliable characteristic, long working life;
• Vacuum sealed register ensures the dial keep free from fog and frost, keep the reading clear in a long
  term service;
• Technical data conform to international standard ISO4064 Class B

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%

Installation

• The installation of water meter meets the installation requirements of ISO4064-2:2005
• The caliber of water meter shall correspond with caliber of pipes and the used flow rate is less than or close to the permanent flowrate. The installation place should avoid exposure, flooding, freeze and pollution, and convenient for installing, removing and reading data.
• The water meter shall be installed horizontally (display surface is upward).
• The sands and stones and other sundries in the pipelines shall be cleared.
• The arrow on the water meter should be the same as the water flow in the pipeline.
• If the water meter is installed on the inlet of the boiler, it is better to install inverted valve on the outlet of water to prevent the return current of hot water and steam will damage the water meter.

Competitive Advantage:

• Compliance to international standards: ISO4064 / GBT778 / Q/320700JR05-2003
• Strict process control
• Advanced calibration equipment
• Engineer team
