KROHNE VFM 1091 - Manual (Page 4)

4
KRONHE MARSHALL vortex flowmeters operate on the Karman
vortex street principle to measure volumetric flow rate of gases /steam
and liquids. VFM 1091 computes normalized volumetric and mass flow
rates from operating & normalized density values supplied through
operator interface.

1. Flow direction and meter position -
•
Flow must always be in the direction of the arrow, bluff side of
vortex-shedding body facing incoming flow i.e. upstream side.
•
Vertical pipe run: upward flow direction
•
Horizontal pipe run: see below
2. Difference between inside diameters of primary head and
pipeline
D
Ν
Meter size of primary head in millimeters or Inches
Φ
Inside diameter of primary head in millimeters Max.
∆Φ
allowable difference between inside
diameters of primary head and pipeline
Ensure that the bore of upstream and down-stream pipes are smooth
and without deposits or scaling of welding beads.
3. Straight, unimpeded inlet and outlet runs
D = Meter size (Nominal Dia. DN)
