METPOINT^® OCV and METPOINT^® OCV compact enable us to provide two products with which you can permanently measure the quality of your compressed air with regard to the oil vapour content.

Advantages of the METPOINT OCV | OCV compact

The details will be clarified more precisely on the following pages. Installation example with METPOINT

Safe
- Reproducible accuracy of the measurement values by utilising reference gas generation (catalytic converter principle)
- Automatic monitoring for the reference gas and sensor electronics
- Issuing and transferring of alarm signal messages

Reliable
- Pressure range from 3 to 16 bar
- Online monitoring for the oil vapour concentrationData transfer to display as standard feature and control centre with customary communication methods

User-friendly
- Visualisation of all measurement values
- Flexible installation

There are however certain differences, which can qualify them more efficiently for the respective application purpose.

ADDITIONAL INFO

Recognised procedure and external test certificate

The eligibility of the utilised measuring procedure in the METPOINT^® OCV for the continuous recording of hydrocarbon vapour and gases in compressed air will be executed via comparison measurements in the PID procedure with reference procedures according to:

›› ISO 8573-5

›› Pharmacopeia (Ph. Eur. 2.1.6)

While the reference procedures according to ISO 8573-5 and the pharmacopoeia are based on a discontinued sampling method, the METPOINT^® OCV measuring procedure provides the advantage of on-line monitoring. This therefore creates the prerequisite to immediately react to an increase in the residual oil content in the compressed air and possible breaching of the limiting values. The METPOINT^® OCV is the first TÜV certified on-line system for recording the oil vapour content in compressed air. It has been certified by TÜV NORD according to the requirements ISO 8573-1.

Simple and safe operation

Both METPOINT^® OCV systems provide output information about the current measurement value (oil vapour in mg/m³), the ISO 8573 oil class as well as the status of the measuring system and its components. In addition, the status of the measuring cell and the purifier will be displayed visually. You therefore have an overview about the measurement values, oil class, system status at all times and know immediately that your compressed air is correct.
