mass flowmeter type MASS 2100, DI 3 - DI 40
Vertical mounting in pipe
Locate the unit low in the pipe system in order to avoid under-pressure in the sensor and con-
sequent air separation in the liquid.
Direction of flow
Static back pressure
Valve
Direction of flow
As far as possible, the liquid should flow up-
wards to make bubble removal easier.
With vertical mounting, a check valve, which
closes on zero flow, must always be installed so
that the liquid cannot flow back and partially
empty the sensor.
The arrow on the sensor indicates positive
(forward) flow direction.

To facilitate 0-point adjustment, a valve with good shut-off should always be mounted in connection
with the sensor.
•
The sensor should be completely filled with liquid.
•
The valve must be closed.
•
Wait a few minutes to let the flow become zero.
Vibration
Locate the flowmeter as far away as possible from components that generate mechanical vibration
in the piping.
Or ensure that there is no direct connection with them e.g. by using flexible connections.
Altenatively, the flowmeter can be located after a bend.
