The metering principle is independent of the flow profile as long as 2. Determine the flow velocity as a function of the size and the

the meter primary. 3. The flow velocity can also be determined from the Flow Rate
Nomographs on Page 5, Fig. 8 and Page 7, Fig. 10.
Grounding

flowmeter primary are to be connected to the ground potential in
accordance with VDE 0100, Section 540. For technical reasons
this should be identical to the potential of the metering fluid if pos- Double flanged reducer

For plastic or insulated lined pipelines the fluid is grounded by uti-
lizing a grounding plate or protection flanges. When there are stray
potentials present in the pipeline a grounding plate is recommend-
ed at both ends of the meter primary.
