mass flowmeter type MASS 2100, DI 3 - DI 40
Application conditions/limi-
tations
The sensor must not be used outside the specifications given on the TAG label on the sensor and
the data given in the handbook, SFIDK.PS.028.L1.02.
Permissible pressure
(PS/PN)
Before taking the sensor into use please read the max. operating pressure (PN) on the sensor
TAG. The operating pressure indicates the pressure to which measuring pipe and connections
have been dimensioned and pressure tested. This, however, is not the case with the sensor
enclosure (i.e. the enclosure covering the measuring pipe).
The enclosure/housing is
not
rated for pressure containment.
When working with operating pressures/media which in case of pipe fractures may cause injuries
to people, equipment or anything else, we recommend to take special precautions when building-
in the sensor i.e. special placement, shielding, pressure release valve or the like.
The sensor enclosure is supplied with a 1/8" nipple. When demounting the nipple, a pressure
release valve can be connected to automatically shut off the flow to the sensor in case of leakage.
For instructions on the mounting, please refer to the section ”pressure release valve”.
Cavitation/
pressureschoks
When installing a mass flowmeter, it is not necessary to take account of components that generate
turbulence, such as pipe bends, T-pieces, valves, etc. because the meter is not affected by inlet
conditions. However, cavitation and air bubbles in the system can disturb measurements and
must be avoided. Heavy pressure shocks (water hammers) must be avoided as they will disturb
measurement and can damage the sensor, dependant of energy in the pressure shock.
Permissible temperature
(TS)
The minimum and maximum temperature rating given on the sensor TAG must not be exceeded.
Corrosive liquids and
gases
Before taking the sensor into use please ensure that the sensor material can withstand possible
corrosion forces that might occur from the liquid or gas in question. This also covers cleaning
agents or CIP liquids (
C
leaning
I
n
P
lace), which might be used on a non, frequent basis.
From the sensor TAG the pipe material are listed according to the EN 13480.
Further material fatigue from abrasive wear due to wearing particles in the liquid must be avoided.
Pressure Equipment Direc-
tive 97/23/EC
From May 30
th
2002 the “Pressure Equipment Directive” is mandatory for all pressure equipment
sold within the EU and EFTA. Products sold outside EU and EFTA are excluded from the directive.
MASS 2100 DI 3 - DI 15 has a diameter < 25 mm, and are according to article 3, paragraph 3 of
the PED/97/23/EC not within the scope of the PED. These meters are classified within the scope
of SEP (Sound Engineering Practice).
MASS 2100 DI 25 and DI 40 falls within the scope of the PED, and are in accordance with the
PED, Fluid group 1 (dangerous fluids, gaseous) according to Article 3, paragraph 3 of the PED/
97/23/EC.
