Product description
VAD DN15 is a compact mechanical water meter platform for potable-water metering in household and light commercial systems. The product concept combines a conventional roller register with an optional battery-powered telemetry module for remote reading and event transmission. The communication function should be declared as an additional functionality without metrological impact where that matches the certified architecture.
Metering principle
- Principle: Mechanical
- The supplied artwork does not support an ultrasonic claim; therefore the master technical datasheet is drafted as a mechanical meter platform.
Metrological data
Data visible on supplied artwork
- Qn 1.5 m³/h
- T50
- MAP16
- +5…+90 °C
- K = 4.440 × 10⁻⁶ m³/imp
Data required in the released EU datasheet
The final released technical datasheet shall declare the certified values for:
- Accuracy / metrological class as applicable to the certified variant
- R-value and orientation, where applicable
- Q1
- Q2
- Q3
- Q4
- Starting flow, if declared
- Maximum permissible error statement
- Temperature class
- Pressure loss class, if claimed
- Sensitivity to flow disturbances, if claimed
- Installation conditions required for declared performance
Notiz
Do not publish product-specific Q1/Q2/Q3/Q4 or R-values until they are taken directly from the EU type-examination certificate or other approved certification documents.
