Level Switches
|
Introduction
Flowline offers the most advanced family of level switch automation and safety solutions for your bulk storage, day tank, process vessel and waste sump applications.
|
Ultrasonic
Offered in PP and PFA with a 1A relay, the intrinsically safe ultrasonic switch is applied in hazardous media including solvent, chemical, hydrocarbon and petroleum.
Capacitance
Offered in both intrusive and non-intrusive configurations with a 1A relay, the general purpose capacitance switches are best for ultrapure water and acid.
Optic
Offered in PP and PFA with a 1A relay, the general purpose optic switch is widely applied in secondary containment leak detection of chemical and wastewater.
Buoyancy
Offered in PP, PVDF and stainless steel with a dry contact closure, the general purpose float switches are ideal for basic water, chemical and light oil applications.

|
|
|
|
Vibration
Offered in Ryton® with a 1A relay, the general purpose vibration switch is ideal for challenging coating, scaling and foaming media such as wastewater and brine.
