Transparent Level Gauge

The Transparent Level Gauge is a highly efficient and reliable instrument designed for the direct visual observation of liquid levels within a container or process vessel. This gauge provides clear and accurate readings, making it an essential tool for industries that require precise monitoring of liquid levels.

The Transparent Level Gauge from IPS Automation is a direct visual level measurement
instrument designed to monitor liquid level, interface level, colour, and clarity inside tanks,
vessels, boilers, separators, and industrial process equipment. It uses two transparent glass
plates mounted on opposite sides of a metallic chamber, allowing operators to see the actual
liquid level through the gauge body. This makes it suitable for applications where direct visibility
of the process fluid is required, especially in high-pressure, high-temperature, corrosive,
coloured, foaming, or interface liquid services.
Unlike reflex level gauges, transparent level gauges allow the operator to observe the real
appearance of the process fluid. This is useful when monitoring liquid colour changes,
contamination, separation between two immiscible liquids, or interface level such as oil and
water. For difficult viewing conditions, an illuminator can be installed behind the gauge to
improve visibility, while mica or protective shields can be used to protect the glass from
corrosive fluids, steam, or high-temperature service.

Allows Fluid Colour and Clarity Observation

Operators can visually check colour, contamination, cloudiness, foaming, or process changes, making the gauge useful for quality-sensitive and process-critical applications.

Compatible with Corrosive Services

With mica shields, PTFE protection, suitable gasket materials, and corrosion-resistant body materials, transparent level gauges can be used for aggressive chemicals and corrosive process media.

Customizable for Project Requirements

Weld Pad Level Gauges can be customized according to vessel radius, measuring range, body material, glass type, gasket material, pressure rating, temperature rating, viewing design, and process media compatibility.

Direct Visual Level Indication

Tubular level gauges provide a clear and immediate view of the actual liquid level inside the tank or vessel, helping operators verify level conditions without depending only on electronic instruments.

Improved Visibility with Illumination

For colourless liquids, low-light areas, or steam-water applications, optional backlighting or illuminators can improve contrast and make the level easier to read.

Safe and Serviceable Design

Isolation valves, vent valves, drain valves, and auto shut-off ball check arrangements can be provided to support safer maintenance, cleaning, and gauge isolation during operation.

Suitable for High Pressure and High Temperature

Transparent level gauges are available in rugged constructions for demanding pressure and temperature conditions, including steam, boiler, chemical, and process plant applications. Compatible with Corrosive Services

Suitable for Interface Level Monitoring

Because the actual liquid can be seen through the transparent glass, these gauges are ideal for observing the separation line between two immiscible liquids, such as oil and water.
