mass flowmeter type MASS 2100, DI 3 - DI 40
If the flowmeters are located close to each other, e.g. in the same pipe section, the meters may
disturb each other in measurement, especially with low flow. Locate the meters with a flexible
connection instead of a permanent connection.
Avoid mounting the meter on the same steel frame. I.e. insulate the meters mechanically.
Important
Before demounting the nipple from the sensor enclosure, please note the following:
Penetration of humidity, liquid or particles into the sensor must be avoided as it may influence the
measurement and in worst case damage the measuring function. This, however, can be avoided
when following the procedure below:
If the meter is supplied as IP 67 or Ex-d compact version, only the output must be threaded. Refer
to either the handbook or the manual. If the sensor is meant for separate mounting, it must be
connected as follows:
Mounting of multiple plug
Mounting of adapter
1. Place the sensor in a dry and clean place and
leave it there to acclimate until it obtains
ambient temperature, best at approx. 20 °C.
2. Be careful when demounting the nipple and
mounting the pressure release valve.
3. Check that the pressure release valve has
been correctly mounted and thoroughly
tightened so that the sealing ring fits tightly.
Always replace old sealing rings by new
ones after each dismantling.
Mount the multiple plug in the adaptor and
tighten the glands on the plug to obtain opti-
mum sealing.
Note the wire colours when connecting the
MASS 6000. Refer to the diagram for electrical
wiring.
For remote installation mount the adaptor on
top of the sensor interface, if not already
mounted.
When fitting the multiple plug, please make sure
that it is correctly oriented (note the little tap).
