A simple glass tube connected to the vessel gives you a direct view of the liquid level. There is no electronics to configure and no signal to troubleshoot.

Tie-rod construction permits 360-degree visibility; C-frame construction is more robust and allows observation from front and rear. Both are available in integral or inline arrangements.
Material integrity is assured through strict chemical composition analysis in a standard laboratory.
Tie-rod for 360-degree visibility; C-frame for front-and-rear observation, both in integral or inline arrangements.
Gland packing design allows the glass tube to be removed and replaced without disconnecting the gauge from the vessel.
16, 19 or 25 mm OD borosilicate glass tube with PTFE packing suits normal and viscous liquids alike.
Flanged, screwed or industrial fittings in vertical or horizontal orientation with standard or extended tube lengths.
Applies to all variants unless otherwise specified

Safety ball-check devices, glass protectors (acrylic or slotted metal), defrost / illuminator accessories and adjustable proximity or reed switch arrangements for level alarm are all available on request.
All four models share the same borosilicate glass tube, scale and connection options. Select by body material and isolation arrangement: PP body for aggressive chemical mediums; SS body for food-grade, pharmaceutical or high-temperature duties; and choose between end-block and integral isolation valve based on whether online maintenance without vessel isolation is required.
PP body with end-block construction. No isolation valve, suited for non-hazardous service where vessel isolation is managed upstream.
PP body with integral isolation valve for online glass removal without vessel shutdown.
SS304 / SS316 body with tie-rod construction. Clean, high-visibility design for general and food-grade process applications.
SS304 / SS316 body with integral isolation valve and C-frame guard for robust high-pressure or high-temperature installations.
