("Custody transfer")
5.1 Placing on market of measuring devices subject to legal
metrological control, inspection of operational devices
All Promass 84 Coriolis gas meters are tested at Hauser Flowtec AG or on an approved
reference test rig (e.g. PIGSAR) using reference measurements.
The devices are placed on the market and put into use by either Hauser Flowtec AG in
accordance with Measuring Instruments Directive, Module D or by an notified body in accordance
with Module F.
The gas meter may then be used in applications subject to legal metrological control. The associated
seal on the measuring device ensures this status.
Regular inspections of operational devices must be carried out in accordance with national
regulations.
5.2 Requirements for commissioning at point of installation
5.2.1 Installation
As far as possible, the Promass 84 Coriolis gas meter must be mounted strainlessly. The metering
system must, in appropriate way, be equipped with a gate valve so that, if necessary, a zero flow can
be achieved for checking and adjusting the zero point. The valve needs not to be protected.
The types, serial numbers and software versions of all the meter modules used at the point of
installation must be compared with the specifications in the accompanying documentation.
Likewise, the electrical characteristics of additional devices which are connected to the outputs of
the Promass 84 gas meter, must be tested.
When securing the gas meter at the point of installation, the parameters relating to measurement
technology

ä
28 ff. must be checked using the parameter list which accompanies the device (see
also CD-ROM: Product Documentation).
The data on the sheet accompanying the device are verified for accuracy, a change in the zero point
and the configuration of device-specific functions. Changes in the parameters relating to
measurement technology at the point of installation must be documented in the acceptance report.
This also applies to a possible necessary zero point corrections (old zero point, new zero point), e.g.
if significant changes in the tensions on the installed meter can not be excluded. The acceptance
report for the device must be kept on file.
If the device is to be subject to legal metrological control, the connecting cables must be secured as
well.
5.2.2 Operating pressure ranges
The Promass 84 gas meter must be used in accordance with the pe,min and pe,max values indicated
on the additional nameplate

å
2. The values must be selected in such a way that the gases or
gas mixtures to be measured occur only in a gaseous state in the designated temperature range.
