GEMÜ offers various function principles for the area of flow measurement systems:
- Flowmeters according to the variable area principle for the measurement ranges from 2-20,000 l/h, suitable for the attachment of limit switches, instrument sensors and reed contacts to detect measurement values and to transmit them.
- Flow transmitters can be used both as pure measurement turbines and as totalizers or batch controllers for measurement ranges from 0.3 – 25,000 l/h. The measurement turbines provide various electrical output signals for further processing.
- A magnetically inductive flowmeter (MID) completes the product range. It can be used for nominal sizes of DN 25 – 300 and be set precisely to the respective application conditions using its electronics. Interfaces such as R232 and Profibus-DP enable uncomplicated integration in fully automated plant control systems.
- SonicLine® ultrasonic flowmeter for corrosive and ultra pure media. The device has no moving parts in the medium flow and has a measuring range from 0.03 – 120 l/min (0.5 – 2000 ml/sec.) depending on the nominal size.
