SP-GA - liquid Flow Switch

SP-GA Flow Switch is designed to give an initial alarm at a very low flow and still be capable of allowing a high full liquid flow passing through when pumps or valves are activated by the micro switch. The function is based on fluid flow activation only and threfore it is not affected by changes in static pressure.
SP-GA comes in dimension DN40. You can use reducti*** for to h***e it in DN32 or DN25. Filters are ***ailable as option.    SP-GA has a mechanical micro switch. You h***e the possibility to chose a set point from 3 l/min up to 70 l/min. The set point is calibrated from factory and can be adjusted in field. Maximum flow is approximately 300 l/min.

EF-G - liquid Flow Switch

EF-G is recommended in applicati*** where low signal point can be combined with large flows passing without creating a large pressure drop.   EF-G comes in dimensi*** DN15 and DN20. The maximum flow is appr. 70 l/min and you h***e the possibility to chose the set point from 1,5 l/min up to 30 l/min.
EF-G has an inductive sensor. Process pressure up to 100 bar. The outlet can be rotated 90º or 180º with respect to the inlet which gives an installation of limited space.

PR1 – liquid Flow Switch of paddle-type

PR1 liquid Flow Switch is suitable for applicati*** with limited demands on accuracy. Its speciality is full flow or no flow. The lowest possible set point in a 50 mm pipe is appr. 100 l/min, the set point increases accordingly with larger dimensi***. It can be mounted on pipe-sizes from DN50 up to DN250, the process connection is 25mm thread (through pipe wall).

The paddle aligns fully with the flow and creates a very ***all pressure drop.
