Installation
Measuring Sensor ORG 12, ORG 22
It is highly advisable to have the installation work done by qualified staff in the manner
described by these installation instructions. The manufacturer will not accept liability for
damage resulting from improper installation.
The measuring transducer is designed for wall mounting and should be installed close
to the measuring sensor.
Install the measuring sensor and lines in accordance with the examples given in
figs. 2 to 7.
Provide a throttling point – e. g. a non-return valve (GESTRA type RK 86) in the main line.
Mount the measuring sensor in a bypass at a lower level than the main line so that any
gas bubbles and flash steam can pass through the main line instead of the sensor. Tap
main line at the side from the bottom to prevent air and dirt particles from flowing into the
bypass.
If the fluid temperature is above the max. ambient temperature:
Screw in vent nipple .
If the fluid temperature is below the ambient temperature:
Remove the plastic lid from the drying cartridge (blue colour) and screw in the drying
cartridge .
If the fluid temperature is very high:
Provide a non-insulated pipe upstream of ORG 12/ORG 22 which will allow the fluid to
cool down to 120 °C when reaching the sensor.
In the presence of large amounts of gas:
Tapping point must be at the bottom of the line – use a welding pocket in accordance with
DIN 2618 (see page 14 fig. 5).
If the condensate can be/is highly contaminated:
Ensure downward flow of the fluid through the glass cylinder (glass cylinder may be
scratched), for installation see page 14 fig. 3.
If this does not help and/or a lot of flash steam builds up ahead of the measuring sensor
fit a separator upstream of the equipment (see page 15, fig. 6).
Avoid flashing, outgassing and the presence of air due to a pressure drop
upstream of the measuring sensor.
The additional connection of the cover flange must be reserved for the
inlet of either wash water or calibration fluid.
