Measurement accessories
METPOINT® OCV
for the measurement in systems up to 40 bar
Dear customer,
Thank you for deciding in favour of the METPOINT® OCV measuring device with sampling probe.
Please read these installation- and operating instructions carefully before mounting and starting up the
METPOINT® OCV measuring device, and follow our directions. Perfect functioning of the METPOINT®
OCV, and thus exact measurement and monitoring of the residual oil content in compressed air, can
only be guaranteed when the provisions and notes stipulated here are strictly adhered to.
These instructions for installation and operation are a supplement to
the installation and operating instructions METPOINT® OCV for the
installation and operation of the measurement accessories to be applied
in systems with an operating pressure of 40 bar.
The installation and operating instructions of the integrated
components are not substituted by these, and they shall still be applied
in their entirety. They should always be available during the operation of
METPOINT® OCV in systems with an operating pressure of 40 bar.

4.3 General safety instructions
DANGER!
Compressed gas!
Risk of serious injury or death through contact with quickly or suddenly escaping
compressed gas or through bursting plant components.
It is the obligation of the operator to ensure that the connected pressure generator is
protected against the exceeding of the maximum operating overpressure and of the
temperature limits at the METPOINT® OCV in the version for the measurement in systems
with an operating pressure of 40 bar.
Make sure that the system is pressureless prior to integrating the METPOINT® OCV in the
version for the measurement in systems with an operating pressure of 40 bar into the
compressed gas system!
Any installation works must only be carried out on the pressureless system. Only use
fittings and connecting elements that are approved for this application. It is of vital
importance to observe the specifications of the respective manufacturer.
Unpressurise the plant prior to any maintenance or repair works!
Check all connections prior to the initial start-up and retighten them if necessary.
Do not exceed the max. permissible operating pressure (see type plate).
Safety instructions
The max. permissible operating overpressure is specified on the type plate and in the
technical data (see "Technical data" section).
Sudden impact through pressure build-up can cause damage and escape of compressed
gas.
Avoid a sudden pressure build-up by operating the valves slowly.
Maintenance, inspection and installation works must be carried out by authorised and
skilled personnel only. Prior to undertaking any measures on the METPOINT® OCV in the
version for the measurement in systems with an operating pressure of 40 bar, the skilled
personnel shall read up on the device by carefully studying the operating instructions. The
operator is responsible for the adherence to these provisions. The respective directives in
force apply to the qualification and expertise of the skilled personnel.
Never make structural modifications to the plant!
Use genuine spare parts and accessories only!
The general safety and accident prevention regulations apply!
DANGER!
Supply voltage!
The operation and maintenance of electrically-powered machines and devices must only be
undertaken by correspondingly qualified and authorised personnel. Prior to carrying out
service measures, no matter which type, the following notes must be considered:
Make sure that no parts of the system are energised and that the METPOINT® OCV cannot
be connected with the electric supply mains during service measures.
WARNING!
Unauthorised interventions!
Any modification of the components that has not been checked and approved by the
manufacturer is potentially dangerous and will void any warranty and liability on the
manufacturer's part.

Equipment Directive
The proper use of the measuring device is the basic requirement for safe operation. Therefore, the
user must proceed as follows:
• The METPOINT® OCV in the version for the measurement in systems with an operating
pressure of 40 bar must only be employed within the pressure and temperature range limits
indicated by the manufacturer on the type plate.
• No welding measures must be undertaken at the housing parts of the devices.
• The maximum operating pressure indicated by the manufacturer on the type plate must not
be exceeded. It is the user's responsibility to install the appropriate safety and control
devices.
• The documents related to the METPOINT® OCV in the version for the measurement in
systems with an operating pressure of 40 bar (manual, operating instructions,
manufacturer's declaration etc.) must be kept safe for future reference.
• No objects whatsoever must be installed at or placed on the METPOINT® OCV in the
version for the measurement in systems with an operating pressure of 40 bar and the
connecting lines.
DANGER!
High pressure!
Risk of serious injury or death through contact with quickly or suddenly escaping
compressed air or through bursting plant components.
