Custody transfer measurement
The measuring device is optionally tested in accordance with OIML R117 and has an
EU type evaluation certificate which authorizes the use in EU type-examination certificates according
to Measuring Instruments Directive 2014/32/EU for service subject to legal metrological control
("custody transfer") for liquids other than water(Annex VII).
The permitted fluid temperature in these applications is –10 to +90 °C (+14 to +194 °F).
The measuring device is optionally tested in accordance with OIML R137 and has an EU type-
examination certificate according to Measuring Instruments Directive 2014/32/EU for service as a
gas meter subject to legal metrological control ("custody transfer") (Annex IV). The permitted fluid
temperature in these applications is –25 to +55 °C (–13 to +131 °F).
The device is used with a legally controlled totalizer on the local display and optionally with legally
controlled outputs.
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 Hauser sales center for national
approvals, which are based on the OIML certificates, for applications with liquids other than water or
gases.
