Direct reading of flow rates of liquids and gases:
- Water treatment, Industrial process (paper mill, textiles etc.), chemical and pharmaceutical industries

The measuring principle is that of the variable area flowmeter, the float is moved by
the fluid inside a calibrated conical glass tube. The borosilicate glass conical tube is
inside a stainles steel protection case with a transparent reading window. These
flowmeters can be calibrated for each fluid, depending on the operating conditions.

Limit value switches
These flowmeters can be equipped with a magnetic float and Reed contacts, triggerpoints adjustable over the entire measuring range.

Analogue output 4-20 mA or 0-10 V
The transmitter is connected to a Hall effect linear signal ruler. The analogue signal (4-20 mA or 0-10 V) is the image of the float position; The transmitter is connected via a connector M12. This output is useful for applications using a PLC. The device is compact with a high level of repeatability.
