Liquid Level Gauge

Factory-direct liquid level gauges — industrial instruments for visual monitoring of fluid levels in tanks, vessels, boilers, and process equipment. Available in glass tube, transparent, reflex, magnetic flap, and aluminum alloy types. Custom configurations and OEM orders welcome.

Types of Liquid Level Gauges

Type Principle Best For
Transparent level gauge Direct visual through flat glass Colored fluids, interface detection, up to 40 bar
Reflex level gauge Prismatic glass light refraction Steam, boilers, high-pressure up to 64 bar
Glass tube level gauge Borosilicate glass tube with cock valves Low-pressure tanks, water, general fluids
Aluminum alloy level gauge Aluminum body with sight glass window Hydraulic tanks, compressors, machinery
Magnetic flap level gauge Magnetic float with color-flip indicator Remote reading, opaque or hazardous fluids

Key Properties

  • Glass material: Borosilicate glass — high thermal shock and chemical resistance
  • Operating temperature: Up to 400°C (reflex type)
  • Operating pressure: Up to 64 bar (reflex type)
  • Connection standards: DIN, HG, JIS, ANSI — specify on order
  • Media compatibility: Water, steam, oils, acids, alkalis, solvents (material-dependent)
  • Custom lengths and configurations available for OEM applications

Typical Applications

  • Industrial boilers and steam generators — water level safety monitoring
  • Chemical and petrochemical process vessels — fluid level control
  • Pharmaceutical reactors and storage tanks — sterile process monitoring
  • Food and beverage production — hygienic tank level gauging
  • Hydraulic systems and compressors — oil level inspection
  • Water treatment and desalination plants — tank level management

Compatible Accessories

Pair with PTFE, fluororubber, or silicone gaskets for leak-free installation. Replacement glass plates available separately in our Level Gauge Glass collection.
