Basic safety notes
Risk of explosion
◗Do not use the equipment in potentially
explosive atmospheres.
Risk of serious injury
◗Make sure that all equipment components are
free of damage.
◗There is a risk of electric shocks when per-
forming measurements on live valves. Make
sure that the valves to be tested are free of
voltage.
◗The valves to be tested are pressurised and
hot. Only perform tests when the following
conditions are satisfied:
◗Avoid skin contact with the valve to be tested
or other system parts.
◗Wear suitable protective clothing during all
measurements.
◗Ensure that there is no escaping fluid around
the valve to be tested.
◗There is a risk of electric shocks when han-
dling defective components.
◗Never open the components of the equip-
ment.
◗Never used damaged components.
◗Make sure that the cables used to charge the
equipment are in perfect condition before-
hand.
Information on property damages
or malfunctions
◗Sudden or strong changes in temperature can
lead to condensate build-up in the equipment.
◗Following temperature changes, leave the
equipment switched off until the equipment
temperature acclimatises to the ambient
temperature.
◗Allow the device to dry out fully in the
event of condensate build-up.
◗There is a risk of malfunctions and dam-
age to electronic components due to static
charges.
Wear electrically insulating shoes when
performing measurements.
◗There is a risk of malfunctions and damage to
electronic components due to incorrect han-
dling.
Never open the components of the equip-
ment.
◗Incorrect placement of the sound probe can
lead to inaccurate measurement results. Only
apply the sensor tip to a bare metallic sur-
face.
◗Performing measurements at various loca-
tions on a valve can lead to measurement
errors. Always apply the sensor tip to the
same measuring point. Apply the sensor tip
vertically to the surface of the valve.

Task and function
Task
The testing equipment VKP 10 is used to test and
analyse steam traps of all types.
The testing equipment consists of a display
device and a sound probe.
Function
The testing equipment measures and analyses
ultrasonic vibrations that occur when steam
flows through functioning steam traps. The ul-
trasonic vibrations are transferred to the tip of
the sensor by pressing the sound probe to the
specified point of reference on the trap body.
The ultrasonic vibrations are then converted
into electric pulses and indicated by the display
device. The test equipment VKP 10 signals only
vibrations within 40 – 60 kHz, as these frequen-
cies constitute the usual vibration range associ-
ated with flowing steam. The user evaluates the
sensed ultrasonic vibrations as part of the com-
parison measurement carried out for reference.

Attention!
Condensate can accumulate in the
equipment when using it after sudden or
strong changes in temperature. This can
lead to malfunctions or damage.
➢Following temperature changes, leave
the equipment switched off until the
equipment temperature acclimatises to
the ambient temperature.
➢Do not charge the equipment in this
time.
Attention!
➢Charge the equipment fully before every
use.
Always charge the batteries before using the
equipment for the first time. It takes around 5
hours to recharge a fully depleted battery.
➢Connect the battery charger to the display
device and the electricity mains.
Performing a measurement
Checking the steam trap
DANGER
Risk of electric shock when checking a
live pipe.
➢Take suitable measures before starting
the check to ensure that no parts of the
pipeline are carrying voltage.
You can do this by earthing the pipeline, for
example.
➢Make sure that the measuring point is free of
paint or dirt.
➢Make sure that you use the same measuring
point as in previous measurements.
➢Mark the measuring point on the steam trap if
necessary.
Attention!
Incorrect placement of the sound probe
can lead to inaccurate measurement
results.
➢Only apply the tip of the sound probe to
a bare metallic surface.
➢Always apply the sensor tip to the same
measuring point.
➢Apply the sensor tip vertically to the
surface of the valve.

Performing measurements
Before checking steam traps, make sure that the
measurement sensitivity of the VKP 10 has been
selected in advance using the rotary switch 7.
The switch position “10” indicates the highest
level of sensitivity. Different steam trap types
generate varying sound levels, even when the
loss of steam and operating conditions are iden-
tical. We recommend the switch position “8” for
GESTRA type-BK steam traps and position “7” for
type-MK models.
Lightly press the sound probe against the surface
of the steam trap. Always place the sound probe
at the same location on the housing when testing
steam traps of the same type. This makes it pos-
sible to compare the steam traps and determine
any changes when repeating the tests.
Steam traps operating continuously, and dis-
charging up to about 30 kg/hr of condensate
from steam pressures lower than 20 bar will
cause no or only a slight deflection of the indicat-
ing meter. Any steam loss is indicated by a pro-
portional meter deflection. The relation between
steam loss and meter deflection depends on the
steam trap type and the used measuring point
on the trap surface. Larger condensate flowrates
and higher service pressures result in louder
flow-generated noises, making it necessary to
reduce the sensitivity setting. To obtain meaning-
ful readings when using the VKP 10, log and use
installation-specific survey data and empirical
test values.
In practice, an exact quantification of the steam
loss is usually only of minor importance. Normal-
ly, an approximate value that allows the detection
of steam loss through steam traps at a tolerable
effort will suffice.
When checking the steam traps, set the rotary
switch to “7” or “8”. A continuous indication be-
tween 6 and 8 on the meter scale indicates that
the trap requires maintenance or replacement.
This indicates steam losses of 1 to 4 kg/hr.

When checking thermal steam traps, position the
sensor tip as follows:
◗At the transition between the cover and the
cover flange
◗On the side of the cover

Special information
Please take into account that ultrasonic sources
like pumps or steam reducing stations in the
proximity of the steam trap to be tested may
falsify the result. In this case, steam loss may be
indicated even though the traps operate correct-
ly. This can be verified by scanning the adjacent
pipelines. If the deflection remains unchanged
or increases, this must be attributed to a foreign
ultrasonic source. Switch off sound emitting plant
components, if possible.
Intermittently operating steam traps cause re-
current meter deflections which may even reach
the end of the scale. Thermostatic traps (with
bimetallic control or membrane regulators) may
operate within the specified pressure and flow-
rate range either continuously or intermittently. In
this case, steam loss can usually be excluded. A
recurrent meter deflection here indicates that the
steam trap is operating correctly.
Thermodynamically controlled steam traps
always operate intermittently. Any steam loss
rises with increasing lift frequency on this trap
type. Only a constantly large meter deflection can
clearly indicate steam loss.
Essentially the same considerations as men-
tioned for thermodynamic traps also apply in
the case of steam traps with open floats. How-
ever, inherent steam loss definitely occurs on
float-operated traps even when the trap operates
intermittently.
Before performing the tests, use the technical
plant data (service pressures, differential pres-
sures, flowrates etc.) to at least estimate wheth-
er the trap flowrate lies within the testable range.
After operation
➢Charge the equipment battery as described in
the section "Measurement preparations".
Servicing the equipment
The equipment does not require any particular
maintenance work.
Replacing the battery
Attention!
➢The battery (9 V, NiCd) of the display
device may only be replaced by the
manufacturer!
The service life of the permanently in-
stalled battery is five to seven years with
normal equipment use. If the battery is
defective, please send the equipment to
GESTRA, Bremen for the battery to be
replaced.
Removing external dirt
Attention!
Risk of damage to the device due to fluid
ingress.
➢Make sure that no fluid can penetrate
into the equipment.
➢Only clean using damp cloths.
➢Remove dirt from the equipment with clean
water and a lint-free cloth.
➢Remove stubborn dirt with a cleaning agent
suitable for the material and a lint-free cloth.
Checking parts for damage
➢Check that all equipment components are in
perfect condition before and after use.
➢Do not bring damaged components into ser-
vice.
➢Replace any damaged components.
