EARL Flow Switches 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.
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.
Control of small flow quantities. Suitable for pulsing flow from piston or diaphragm pumps.
