3.1 Installation
Requirements
The device measures the flowrate in both directions. The factory
default is forward flow, as shown in Fig. 3.

The following items must be observed:
3.1.1 Electrode
axis
Electrode axis (1) should be horizontal if at all possible or no more
that 45° from horizontal.

≥
3 x DN
≥
2 x DN
DN = Flowmeter primary 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 primary.
•
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.

3.1.4 Horizontal
connections
•
Meter tube must always be completely full.
•
Provide for a slight incline of the connection for degassing.

3.1.5 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).

3.1.6 Installation in the vicinity of pumps
•
For flowmeter primaries which are to be installed in the vicinity of
pumps or other vibration generating equip-ment, the utilization of
mechanical snubbers is advantageous.
