Custody transfer (optional):
!
Note!
As an option, Promag W 800 is tested in accordance with OIML R49 and has an EC type-examination
certificate as per 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).
It is used with a legally controlled totalizer on the local display.
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 lead
seals on the transmitter or sensor.
These lead seals may normally only be opened by a representative of the competent authority for legal
metrology controls.
!
Note!
After putting the device into circulation or after sealing the device, operation via the onsite display, via
the Config 5800 software operating tool or via GSM/GPRS 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.
