SIGMA’s Oil Level Gauge / Indicators (Acrylic) are designed for measuring / indication of level of oil or other transmission liquids. The principle of operation is liquid maintaining its level by virtue of gravity. The Oil Level Gauge comprises of a solid block of transparent acrylic (oil chamber) with 
graduations as required. The Oil Level Gauge is connected to the storage tank through a single limb or by having two connections drawn from the chamber to the side of the tank. It also contains a vent and a drain. This is typically used for low pressure and low temperature applications.
SIGMA’s Oil Level Gauge / Indicators (Glass) is rugged, compact and reliable gauge for visual indication of oil levels in small tanks. The Level Gauge consists of a toughened borosilicate gauge glass tube fitted between metallic end blocks and banjo bolts through a set of o-rings. A slotted steel guard is provided enclosing the glass guage to provide protection from accidental damage. The gauge is mounted parallel to the tank, to form a closed loop causing tank liquid to seek its level in the gauge.
