Non-intrusive level measurement systems utilizing magnetic float technology and reflex glass gauges for safe, accurate liquid level indication in tanks, pressure vessels, boilers, and process equipment across demanding industrial applications.
Liquid level gauges are essential instrumentation for continuous monitoring of fluid inventories in industrial vessels. Our portfolio encompasses two complementary technologies: magnetic level indicators utilizing bypass chamber principles, and armored glass level gauges providing direct visual observation through reflex or transparent glass sections.
These level measurement solutions eliminate the safety risks and maintenance burdens associated with traditional direct-reading glass tube gauges, while delivering superior accuracy and operational reliability in high-pressure, high-temperature, and corrosive service conditions.
Sealed bypass chambers and armored construction isolate operators from hazardous process fluids at extreme pressures and temperatures.
Magnetic and reflex glass technologies operate purely mechanically—no electrical power needed for continuous level indication.
Readings unaffected by process fluid optical properties, refractive indices, color changes, or ambient lighting conditions.
Rugged construction with no glass-to-process contact reduces fragility and extends service life in demanding applications.
From magnetic bypass indicators for extreme conditions to armored glass gauges for direct visual observation.
Bypass chamber systems utilizing magnetic float assemblies that transmit level position through non-magnetic chamber walls to external flag or follower indicators.
Armored flat glass assemblies utilizing prismatic reflex glass that displays liquid as black and vapor as silver-white through light refraction principles.
Dual-glass armored assemblies with transparent flat glass sections on both sides of the liquid chamber for color and clarity observation.
ASME-compliant reflex borosilicate glass gauges specifically engineered for steam service with water appearing black and steam displaying white.
Understanding the contactless magnetic coupling principle that enables safe, accurate level measurement.
A vertical bypass chamber constructed from non-magnetic stainless steel or polymer is connected to the vessel via top and bottom process connections. Process fluid flows freely into the chamber, establishing identical level as the main vessel.
An internal float containing permanent magnets rides on the liquid surface within the bypass chamber. Float specific gravity is calibrated to the process fluid density to ensure accurate buoyancy and positioning.
Magnetic fields from the float penetrate the non-magnetic chamber wall, actuating external flag indicators or followers. As liquid level changes, the float rises or falls, magnetically driving the external indicator to display the corresponding level position.
The magnetic coupling principle operates without electrical power and remains functional during power outages. Indicators are magnetically stabilized to resist vibration-induced errors and provide reliable readings in dynamic process conditions.
