Category 2 equipment
May be installed in zone 1 and zone 2.
Category 1 equipment
Sensor MASS 2100 may be installed in zone 0,
zone 1 and zone 2.
Catetory 2 equipment
Signal converter MASS 6000 Ex-d may only be
installed in zone 1 and zone 2.
Mount the sensor on a vibration-free wall or
steel frame as shown.
Ensure that the sensor is not emptied of liquid
(during normal operation) otherwise incorrect
measurement will occur.
With low flow, horizontal mounting is recom-
mended, in this position air bubbles are
easier to remove.
Locate the sensor low in the system in order to
avoid an under-pressure in the sensor seperat-
ing air/gas in the liquid.
If the liquid is volatile or contains solid
particles, vertical mounting is not recom-
mended.
Always locate the flowmeter as far away as
possible from components that generate me-
chanical vibration in the piping.
Cross talk between sensors mounted close to
each other may disturb the measurement. To
avoid cross talk never mount more than one
sensor on each frame and mount flexible hose
connections between the sensors as shown.
To facilitiate zero-point adjustment, a valve with
tight shut-off should always be mounted in con-
nection with the sensor as a proper zero-point
setting is essential for a good accuarcy.
Note
Please read and follow the directions stated in
the instruction DKFD.PI.028.P1.52 regarding
build-in of sensor.
The instruction is supplied with the sensor.
