PURPOSE OF THE PRESSURE RIG
The supplementary device "high pressure rig " serves for a safe installation and fastening of
the CS sensors VA 300 and VA 400 under pressure. It is strongly recommeded to be used
for gas or air pressures from 10 bar. It is important and absolutely necessary to read the
instruction manuals of the sensors VA 300 and VA 400 prior to the installation.
MOUNTING OF THE DEVICE
• Set up measuring site with screw neck (G1/2" outer diameter) according to the
mounting instruction of the sensor VA 500.
• Screw on the high pressure rig pressure-tightly and make sure that the ball valve
can be opened and closed.
• Close ball valve before mounting the sensor.
MOUNTING OF THE SENSOR
• Insert the upper plate (3) which has not been fixed yet with its notch into the slot
below the sensor head.
• Connect the flexible mounting thread of the sensor VA 500 gas-tightly
to the ball valve.
Attention: Sensor tip is not allowed to touch the ball of the ball valve.
• Adjust the wing nuts (6) that way that the upper plate is secured upwards .
• Adjust the counter nuts (A) as stop position of the upper place for the operating
position of the sensor (typically in the middle of the pipe).
INSTALLATION OF THE SENSOR
• After opening the ball valve please insert the sensor into the pipeline by
permanently screwing of the wing nuts.
• Upon reaching of the operation position of the upper plate please fix the device
with the wing nuts and the counter nuts.
• Tighten the adapter sleeve of the sensor screwing according to the mounting
instruction of VA 500.
REMOVAL OF THE SENSOR
• Slightly release the adapter sleeve of the sensor screwing.
• Release constantly the wing nuts of the high pressure rig. If there is a sufficient
operating pressure the sensor will be pressed back by the medium through the ball
valve as far as it will go into the sensor screwing.
• Close ball valve carefully.
• Before removal of the sensor from the device please screw the wing nuts
at least by the thread length of the sensor screwing.
• For safety reasons please close the outlet of the ball valve with a G1/2“ stopper.

ALIGNMENT OF THE SENSOR
Safety information must be observed.
Assembly is carried out by inserting the connection thread (1/2“ thread, SW 27) into the
connection piece of the ball valve.
Once the sensor has been aligned, the adapter sleeve must be tightened with the stipulated
torque (20 - 30 Nm - SW 17).
Attention: Alignment of the sensor must not be modified when tightening the connection
thread and adapter sleeve. In this case please check the immersion depth and alignment
again and correct if necessary. The angular deviation should not be greater than ± 2° in re-
lation to the ideal position as otherwise the measuring accuracy will decrease.
An undisturbed flow progression is achieved if the sections in front of the sensor (inlet) and
behind the sensor (outlet) are sufficiently long, absolutely straight and without any obstruc-
tions such as edges, seams, curves etc.
For more details please see the instruction manuals of the consumption sensors.

The sensor is then inserted to the required immersion
depth and aligned according to the direction of air flow as
described on page 3. A depth scale engraved on the
probe tube, a flow alignment arrow and an aligning device
will be of help to you.
