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.
