Furthermore, a minimum distance between flowmeter and pumps and valves must be
observed.
It is also important to centre the flowmeter in relation to flanges and gaskets.
Make sure that the flowmeter is positioned as low as possible to prevent air from being trapped
in the flowmeter at the transducers.
Find a position on the pipeline where the inlet pipe to the flowmeter has a straight length as
specified below.
Note
MID-approved FUE380 systems
Minimum straight inlet pipe: 10 x pipe diameter, minimum 1 m. See further recommendations
below.
Single bend
1 x 90° bend
L2: Min. 10 x pipe diameter
L1: 3 x pipe diameter
Dual bend
2 x 90° bends in the same plane
L2: Min. 10 x pipe diameter
L1: 3 x pipe diameter
