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).
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.

measurement accessories
10 Measurement accessories METPOINT® OCV 40 bar
5 Field of application and proper use of the METPOINT
®
OCV 40 bar
measurement accessories
The METPOINT
®
OCV measurement accessories serve to expand the operating pressure range of the
METPOINT
®
OCV to 40 bar. With this, the stationary measurement and monitoring of the vaporous
and gaseous residual oil content of the compressed air (ISO 8573:2001) in systems with an operating
pressure of40 bar is possible. Any other use is considered improper.
The manufacturer and the marketer shall not be liable for the consequences of improper use; the user
and operator alone is responsible for all risks that may arise.
The proper employment and use of the METPOINT
®
OCV according to directions requires the exact
compliance with the installation instructions, in particular in respect of:
•The place of installation, installation conditions
•The voltage supply and frequency
•Pressure, temperature and humidity of the inlet air
•Ambient temperature
•The measuring device is supplied as accepted in the factory. The user only needs to establish
the connections with the supply mains and interconnect the components, which is described in
the following chapters.
WARNING!
Employment for the prevention of dangerous conditions!
A device of the METPOINT
®
OCV series must not be employed as the sole means of
preventing dangerous conditions at machines and plants.
Machines and plants must be constructed in such a manner that defective conditions do not
lead to a dangerous situation for persons or plants.
WARNING!
Improper use!
The METPOINT
®
OCV measuring devices and the accessories offer state-of-the-art
technology and are operationally safe. Residual risks may emanate from the measuring
device and the accessories when improperly installed, employed, or operated by untrained
personnel.
The METPOINT
®
OCV measuring devices and their accessories must only be used by
qualified and authorised personnel and exclusively in accordance with the technical data.

IMPORTANT!
Danger through damaged components!
Under no circumstances should you start up damaged components. Defective
components can impair the operational reliability and cause further damage.
The function and service life of the METPOINT
®
OCV in the version for the measurement in systems
with an operating pressure of 40 bar depends on the conditions at the place of installation. This place
must meet the following requirements:
1. Weather-proof and frost-free installation within a building.
2. The ambient temperature must not drop below or exceed the indications on the type plate.
3. The installation conditions in the separate installation and operating instructions need to be
observed and followed.

Operating princip e of the METPOINT® OCV 40 bar
Measurement accessories METPOINT® OCV 40 bar 13
8 Operating principle of the METPOINT
®
OCV 40 bar
The METPOINT
®
OCV in the version for an operating pressure of 40 bar was developed for the
detection of vaporous and gaseous hydrocarbons in compressed air that is free from aggressive,
caustic, toxic, flammable, and fire-accelerating constituents.
To determine the residual oil content in systems with an operating pressure of up to 40 bar(g), a partial
volume flow can be taken from the system, and the system pressure reduced to 7 bar(g). With the
reduced operating pressure, the medium flows through the METPOINT
®
OCV.
The measuring probe of the METPOINT
®
OCV is integrated into the pipework system of the customer.
The provided ball valve allows for the separation of the METPOINT
®
OCV from the system for
maintenance and calibration, without needing to interrupt the compressed-air supply. For the reduction
of the operating pressure, a special pressure reducer is installed.
For the tubing from the pressure reducer to the METPOINT
®
OCV, a stainless steel pipe Ø 6 x 1 mm is
used. The length of the pipework must not exceed 1000 mm.
The medium travels at approximately 2 l/min through the METPOINT
®
OCV, which means that the
"loss" of compressed air through the measurement in the withdrawn partial flow is negligible.
