Assembly Of The Flowmeter; Figure 4: Mounting Examples For Flowmax 42I - MIB Flowmax 42i Operating Manual

Assembly and installation
When using pumps, Flowmax 42i must be installed in flow direction on the
pressure side, in order to ensure sufficient pressure. The maximum pressure
rating of Flowmax 42i has to be considered.
WARNING!
Do not exceed the maximum pressure allowance for of the Flowmax 42i
(see section 5.3 Technical specifications). Exceed the maximum pressure
can lead to destruction of the Flowmax 42i.
For correct volume flow measurements straight and unobstructed inflow and
outflow distances have to be observed. Starting from the connection thread
these straight and unobstructed flow zones must be:
Nominal diameter
Inflow distance
Outflow distance

2.2 Assembly of the flowmeter

The flowmeter is mounted into a pipe system by using the mechanical
connection. Flowmax 42i should be mounted vertically into the pipe for the best
measuring performance. Do not install the flowmeter after a dosing valve where
the flowmeter can run empty. Placing the flowmeter after a dosing valve and
allowing it to run empty will cause a measuring deviation at the next
measurement. To avoid bubbles in the liquid, Flowmax 42i should be installed
on the pressure side of the pump.
It is recommended to place the pump in the same plane as the container. Thus,
the pump runs independently full and there is caused no vacuum when
promoting.

If it is not possible to mount the flowmeter vertically, then mount the flowmeter
in a location where the pipe will be filled at all times. The best measuring result
is achieved if bubbles do not pass through Flowmax 42i.
