Custody transfer measurement
As an option, Promag W 400 is tested in accordance with OIML R49 and has an EC type-
examination certificate according to Measuring Instruments Directive 2004/22/EC (MID) for service
subject to legal metrological control ("custody transfer") for cold water (Annex MI-001).
The permitted fluid temperature in these applications is 0 to +50 °C (+32 to +122 °F).
The device is used with a legally controlled totalizer on the local display and optionally with a legally
controlled pulse output.
Measuring devices subject to legal metrological control totalize in both directions, i.e. all the outputs
consider flow components in the positive (forward) and negative (reverse) flow direction.
Generally a measuring device subject to legal metrological control is secured against tampering by
seals on the transmitter or sensor. These seals may normally only be opened by a representative of
the competent authority for legal metrology controls.
• After putting the device into circulation or after sealing the device, operation is only possible
to a limited extent.
• Detailed ordering information is available from your local Endress+Hauser sales center for
national approvals as cold water meters based on OIML R49.
