Selection guidance and FAQs
Level gauge or level switch?
A level gauge indicates liquid level, while a level switch provides a switching signal at a set position. Start with magnetic or glass gauges for local indication, or float switches for level alarms. Confirm remote signal requirements separately.
Comparing magnetic, reflex and transparent gauges
Magnetic gauges couple a magnetic float to an external indicator. Reflex gauges use optical reflection to distinguish liquid and gas, while transparent gauges allow observation through front and rear glass. Materials, connections and operating limits depend on the selected model.
Information for level gauge selection
Provide the medium, specific gravity or density, operating and design temperature/pressure, viewing range, orientation, connection spacing and connection specification. Include alarm or transmission requirements when applicable.
