for low gas- or liquid flows type 41vS

The unit has been developed for long-term operational use and controls liquid flows from 0.1 l/h or gas flows from 20 l/h referred to air with standard conditions. The unit is suitable for horizontal pipes with threaded process G ¼. The set point is factory set.

Operation

The flow directed upwards lifts a float. When decreasing the set point a permanent magnet contained in the float operates a reed contact. With normal flow the float is situated at the stop. The pressure loss is kept down by means of overflow tubing

Advantages

Control of small flow quantities. Suitable for pulsing flow from piston or diaphragm pumps. Low cost unit for OEM applications. Suitable for the use in intrinsically safe circuits. Differing material combinations for aggressive media.

Suitability

• Control of gas odorization.
• Control of extraction.
• Leakage control.
• Overflow control.
