OI series oval wheel meters

Oval wheel meters of the OI series are used especially for highly viscous media. The measuring accuracy is maintained even at high operating temperatures and pressures.

With each rotation, the oval wheels convey four partial volumes (delimited between the oval wheel and the measuring chamber) through the meter. The number of revolutions is an exact measure of the flow rate.

Oval wheel meters are excellent volume and flow meters with the following advantages:

• High measuring accuracy

• Very high reproducibility

• Long-term stability over many years

• High reliability through the use of new technologies, thus safe investment

• Very compact design

• Wide range of materials

• Wide viscosity range 0.3-100000 mPa.s

• NO inlet / outlet sections required

• Zero point adjustment not required

• Also for custody transfer applications

OI series oval wheel meters

The oval gear meters of the OI series are particularly suitable:

•      for custody transfer applications

•      for nominal sizes up to DN 100 (DIN / ANSI)

•      for highly viscous media, since there is only a low pressure drop

•      for high demands on measuring accuracy and reproducibility

•    even at high operating temperatures

•    even at pressures up to PN 40

Special gearing

The oval gear meters of the OI series are available with normal teeth or with special teeth. A special toothing is recommended to reduce the pressure loss and for viscosities greater than 150 mPas.

Equipment
An extensive range of additional devices is available for the oval gear meters of the OI series, e.g. B. mechanical, pneumatic, electrical and electronic sensors, whose signals can be used for remote counting, flow measurement and control, as well as for integration into higher-level automation systems. They can also be used for dosing suitable quantity preselection devices with suitable valves of various designs and working methods.
