Weld Pad Level Gauge

The Weld Pad Level Gauge is a high-precision instrument designed for direct and reliable liquid level measurement in various industrial applications. This robust gauge is directly welded to the process vessel, ensuring seamless integration and eliminating the need for additional fittings or connections. Ideal for high-temperature, high-pressure, and corrosive environments, the Weld Pad Level Gauge provides accurate and continuous level monitoring.

The Weld Pad Level Gauge from IPS Automation is a direct-mounted visual level measurement
solution designed for reliable liquid level indication in tanks, vessels, pressure vessels,
separators, silos, mixers, reactors, and industrial process equipment. Unlike conventional level
gauges that require additional nozzle connections, flanges, gaskets, or fittings, a weld pad level
gauge is welded directly onto the vessel wall, creating a permanent and leak-resistant
installation with fewer potential leakage points.
This gauge is suitable for demanding industrial applications involving high temperature, high
pressure, viscous liquids, corrosive media, and limited-space installations. The viewing section
allows operators to visually monitor liquid level directly, supporting safe process control, quick
inspection, and continuous level observation. Weld pad level gauges are commonly
manufactured using stainless steel, Hastelloy, Duplex stainless steel, or other corrosion
resistant alloys, with borosilicate or toughened glass selected according to pressure and
temperature requirements.

Accurate Visual Level Monitoring

The gauge provides direct visual indication of liquid level, allowing operators to quickly verify process conditions without depending only on electronic instruments. This supports better process visibility and operational control.

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 and Leak-Resistant Installation

The weld pad design allows the gauge to be welded directly onto the vessel wall, reducing the need for additional fittings, flanges, and gasketed joints. This helps minimize potential leak points and improves installation reliability.

Durable and Long Service Life

Robust construction, strong glass protection, and corrosion-resistant material selection help ensure dependable performance, reduced wear, and long operational life in industrial applications

Ideal for Viscous and Difficult Media

Weld pad level gauges are suitable for high-viscosity liquids, semi-solids, and process fluids containing solids where traditional level gauges may not perform effectively.

Reduced Maintenance Requirement

The permanent welded installation and simple visual measurement design reduce the need for frequent maintenance. With no moving parts in contact with the process liquid, the gauge supports reliable long-term operation.

Space-Saving Design

The direct weld-mounted construction makes the gauge useful for compact installations, small vessel areas, offshore systems, ships, and equipment layouts where conventional external gauge assemblies may require more space.

Suitable for Harsh Industrial Conditions

With material options such as SS316L, Duplex stainless steel, Hastelloy, and other corrosion resistant alloys, weld pad level gauges can be designed for corrosive fluids, high temperatures, high pressures, and aggressive process environments.
