Tubular Level Gauge or Level Indicator is a simple, yet effective device that helps in measuring direct reading of liquid levels in atmospheric tanks, pressurized tanks, panels and similar vessel.
This is connected with the tank in parallel through thread or flanged connection so that the tank liquid seeks out to the gauge indicator. It comprises a glass or acrylic tube, Gauge Valves with ball check arrangement and Tube Protection Guards with 360-degree visibility.

Tubular level gauges are widely used in:
They are perfect when direct visual level confirmation is required without any electronics.
Tubular level gauges are preferred in many applications because they:
They are ideal for basic level monitoring and backup indication.
360° visibility means the tube is protected with a guard design that allows the operator to view the level from different angles, improving readability and operator convenience—especially when used in panels, skids, and compact process areas.
Petronash tubular level gauges are available with:
Borosilicate glass tube – high clarity, better temperature resistance, widely used for industrial applications
Acrylic tube – lightweight and impact resistant, suitable for less demanding services
Tube selection depends on application, environment, and safety preference.
