If the condensate contains suspended
solids (scratching of the glass) installation
as per Fig. 5 should be chosen. If this does
not help and/or a large amount of flash
steam escapes install a separator
upstream of the sensor (Fig. 8)
1. Lid and base can be screwed
turned through 90°.
2. Screw in nipples , screwed unions
and ball valves supplied with the
sensor (use teflon tape or hemp for
sealing).
3. They have to be fitted into the lid and
base or directly at the inlet, outlet or
purging point.
4. The screwed unions facilitate
positioning of the ball valves so that the
levers can be arranged in one plane
(front).

Screw in vent nipple when the fluid
temperature is above the max. ambient
temperature (Fig. 2).
When the fluid temperature is below the
ambient temperature remove the plastic lid
from the drying cartridge (blue colour)
and screw in the drying cartridge. (Fig. 2)
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.
The second inlet at the lid must be open
for the rinsing water or the calibrating fluid.
In the presence of large amounts of gas
the tapping point must be at the bottom of
the line – use a welding pocket in
accordance with DIN 2618 (Fig. 7, Pos.*)
In the case of very contaminated
condensate: downward flow of the fluid
through the glass cylinder
ORG 12/ORG 22
Install and wire ORG 12/ORG 22 in
accordance with the examples given in
figures 4 to 9.
Mount ORG 12/ORG 22 in a bypass at a
lower level than the main line so that any air
and flash steam can pass through the main
line.
To ensure a flow through the bypass a
throttling point should be provided in the
main line, e. g. GESTRA non-return valve
type RK 66.
Tap product line at the side from the
bottom to prevent air and dirt from
flowing into the bypass.
Any pressure drop upstream of the sensor
which might lead to the release of gases or
to flashing must be avoided.
