Installation Requirements

The device measures the flowrate in both directions. The factory
default is forward flow, as shown in
Fig. 8
The following items must be observed:
3.6.1

Electrode axis

Electrode axis (1) should be horizontal if at all possible or no more
that 45° from horizontal.
Fig. 9
3.6.2

In- and outlet pipe sections

Straight inlet section
≥ 3 x DN
DN = Flowmeter sensor size
• Do not install fittings, manifolds, valves etc. directly in front of the
meter tube (1).
• Butterfly valves must be installed so that the valve plate does not
extend into the flowmeter sensor.
• Valves or other turn-off components should be installed in the
outlet pipe section (2).
• For compliance with the measuring accuracy, observe the inlet
and outlet pipe sections.

3.6.3

Vertical connections

• Vertical installation for measuring abrasive fluids, preferably with
flow in upward direction.

3.6.4

Horizontal connections

• Meter tube must always be completely full.
• Provide for a slight incline of the connection for degassing.
Fig. 12
3.6.5

Free inlet or outlet

• Do not install the flowmeter at the highest point or in the draining-
off side of the pipeline, flowmeter runs empty, air bubbles can
form (1).
• Provide for a siphon fluid intake for free inlets or outlets so that
the pipeline is always full (2).

Strongly contaminated fluids

• For strongly contaminated fluids, a bypass connection according
to the figure is recommended so that operation of the system can
continue to run without interruption the during the mechanical
cleaning.
