EF-G Series Liquid Flow Switch

EF-G Series Liquid Flow Switch

Brand: Eletta

EF-G is recommended in applications where low signal point can be combined with large flows passing without creating a large pressure drop. EF-G comes in dimensions DN15 and DN20. The maximum flow is appr. 70 l/min and you have 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.
