Pall Water Sensor series WS08 are specially designed for the measurement of water
content in oil.

The measured and the calculated values are available on two freely scaleable and
configurable analogue outputs. In addition, the relay output can be used for alarms and
process control (no relay available with RS485 options).

The modular housing enables a user-friendly operation and a quick
replacement of the sensor unit for service purposes.

3. INSTALLATION

3.1 Installation of the housing

The necessary dimensions for the mounting holes can be found
in the drawing to the left.

3.2.1

General safety instructions for installation

The Water Sensor probe is designed for use with pressures up to 20 bar
(290 psi). Precautions therefor

e need to be taken when installing or
removing the probe to ensure that it is not ejected from the system at
high velocities. The design of the probe is such that only when the gland
is fully unscrewed can the probe be removed form the system.

3.2 Installation of the probe

The probe should be located somewhere in the system where fluid will steadily
flow past the probe tip. A return line, or the wall of a reservoir are usually suitable.
Avoid locations where the fluid is frequently stagnant; also avoid places where
water or dirt/sludge could collect around the probe.

Installation depth: 100 mm probe 23 - 65 mm

3.2.2 Installing a bushing/stub

The standard probe without ball valve requires either a ½” BSPP/ISO
or a ½“ NPT female bushing to be welded to the pipe or reservoir
where the probe is to be located. The NPT bush is required for the –
BO8 option probe. The long probe, when supplied with a ball valve,
requires a male threaded stub at the installation location. The
BSPP/ISO stub must be suitable for use with a bonded seal or metal
sealing washer.

Unless a suitable threaded port is already available, a ½” bush/stub
will need to be welded to the pipe or reservoir, the fluid having been
drained. Suitable cleaning/flushing procedures will be necessary once
the bushing/stub is fitted.

3.2.3 Installing the probe, without ball valve

Unscrew the gland-nut completely and check that the o-ring on the
cone of the gland is in good condition. If it is cut or damaged, replace
the o-ring.

Apply thread tape (-B08 option) to the thread of the nipple, or fit a
suitable seal ( C08 option, bonded seal or metal sealing washer). Fit
the nipple into the bush. Tighten sufficiently to ensure a fluid seal.
Slide the probe through the gland to locate the probe tip in the fluid
flow, and tighten the gland lock-nut onto the nipple to a torque of
30Nm (22 lbf ft). If a torque spanner is not available, firmly hand­tighten the nut, then spanner-tighten a further 50° (approximately 1
flat). Check that the probe is not free to slide in the gland – tighten
further if it can be moved by hand. Fill the system, pressurise to
normal working pressure, and check for leaks. For safety reasons,
keep away from the probe while the system is being pressurised, until
it is established that the probe will not be forced through the gland by
the pressure.

3.2.4 Installing the probe, with ball valve.

a) With the valve open, fit a suitable seal, or apply thread tape if
appropriate, and screw the valve onto the stub so that the handle
of the valve points away from the stub. Tighten sufficiently to seal
the joint. Close the valve, and fill/pressurise the system.

b) Unscrew the gland-nut completely and check that the o-ring on
the cone of the gland is in good condition. If it is cut or damaged,
replace the o-ring. Fit a suitable seal, or apply thread tape if
appropriate, and fit the nipple into the bush. Tighten the nipple
sufficiently to achieve a fluid seal. Screw the gland-nut onto the
nipple, sliding the probe back until the stop-ring contacts
the gland.

c) Hand-tighten the gland nut until the probe is just free to slide/turn
within the gland, and slowly open the ball valve – there may be a
very slight leak of fluid around the gland-nut. Firmly and steadily
press the probe through the gland until the tip is in the flow of fluid.
Keeping the probe in position, tighten the gland-nut to 30Nm
(22 lbf ft). If a torque spanner is not available, firmly hand-tighten
the nut, then spanner-tighten a further 50° (approximately 1 flat).
Check that the probe is not free to slide in the gland – tighten
further if it can be moved by hand. Tightening the gland-nut should
eliminate the small leak which may occur during installation. For
safety reasons, keep away from the probe while the system is
being pressurised, until it is established that the probe will not be
forced through the gland by the pressure.

Note that a force of at least 1 kgf per bar of pressure (1.7 lbf per 10 psi)
is necessary to press the probe through the gland with the system
under pressure. Although the probe is designed for operation at up to
20 bar (290 psi) system pressure, it will be difficult to push the probe
through the gland and valve at pressures above about 4 bar (58 psi),
and there will be risk of damage to the probe. Ideally the system
should be depressurised to install the probe; the valve allows
installation/removal of the probe without draining the system.

3.3 Removal of the probe.

3.3.1 Removal of the probe, without ball valve.

a) Either completely isolate and depressurise the system where the
probe is located, or depressurise the whole system and drain it
until the fluid level is below the probe location.

b) Carefully loosen the gland nut, and having checked that there is no
residual pressure in the system, unscrew the gland-nut completely
and withdraw the probe.

3.3.2 Removal of the probe, with ball valve.

a) Depressurise the system. This is essential if the operating pressure
is above about 4 bar (58 psi), and recommended for lower pressures.

b) Carefully loosen the gland-nut – if the system is still pressurised,
apply a force along the probe to ensure that it is not forcibly pushed
back through the gland. Once the probe is free to move, withdraw it
through the gland until the stop-ring on the probe makes contact
with the gland. Close the valve. Do not force the valve closed if
there is a resistance, but investigate why the probe has not been
fully withdrawn.

c) Fully unscrew the gland-nut and withdraw the probe from the
valve assembly.

For reinstallation follow the instructions 3.2.2 or 3.2.3, omitting the
installation of the nipple, which should already be in place.
