More informations

The DOZ07 ova gear flowmeter measures the volume flow of liquid media with a viscosity of up to 500.000 mm²/s, regardless of the actual viscosity of the medium.

In a measuring chamber, two toothed oval gears are rotated by the flowing medium. Each rotary movement transports a defined quantity of liquid through the meter. This rotational movement is detected by a reed contact and output as a pulse. The output frequency of these pulses is directly proportional to the flow rate.

Optionally, the device can be combined with an on-site display, which also offers an analogue or pulse output.

In addition to the connection size in combination with the measuring range, various material combinations, sealing materials and process connections ensure a wide range of applications.

Typical applications

The DOZ07 oval gear flowmeters are used wherever the flow rate of liquids with different viscosities has to be measured reliably and cost-effectively. Due to the many material combinations, the meters are designed not only for standard applications but also for many chemical applications, e.g. for liquids based on hydrocarbons.

Due to the high accuracy of the oval gear flowmeters, they are generally used for high-precision measuring tasks.
