*) TU/F = turbidity units of Formazin suspension, ppm = parts per million

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.
