How Our In-House Testing Ensures Precision in Tubular, Reflex & Transparent Level Gauges

In the world of industrial process control, accuracy and reliability are critical. At Thermal Instrument, we understand that precision in level measurement is paramount for ensuring safety, efficiency, and quality across industries. That’s why we’ve developed state-of-the-art in-house testing facilities that guarantee the performance and reliability of all our Direct Visual Level Gauges—including Tubular, Reflex, and Transparent Level Gauges.

Why Testing Matters in Direct Visual Level Gauges

Level gauges that provide direct visual indication, such as Tubular, Reflex, and Transparent types, are vital for monitoring fluid levels in various applications. Whether operating in low-pressure tanks or high-pressure boiler systems, these gauges serve as essential safety and control instruments. Any deviation in measurement can lead to operational inefficiencies or safety risks.

That’s why rigorous testing is conducted to ensure that every gauge, regardless of type, meets the highest standards of precision, strength, and reliability.

Comprehensive Testing Procedures at Thermal Instrument

Our in-house testing facilities are fully equipped to conduct a range of advanced evaluations. These ensure that each level gauge—Tubular, Reflex, or Transparent—performs flawlessly even under the most demanding industrial conditions:

  1. Hydrostatic Testing

We subject all gauges to hydrostatic pressure tests to validate their structural integrity. This ensures they can safely operate under their designated pressure conditions without risk of failure.

  1. PMI (Positive Material Identification) Testing

Using PMI tools, we verify that the materials used in our level gauges meet the exact specifications for strength, corrosion resistance, and industrial-grade durability.

  1. Helium Leak Testing (on contract)

For applications where leak-tightness is mission-critical, we conduct helium leak testing to detect even the smallest imperfections that could impact gauge performance.

  1. Radiography Testing (on contract)

For highly sensitive applications, radiographic testing is employed to inspect the internal structure of the level gauge components, ensuring they are free from defects.

  1. Calibration Testing

All level gauges undergo meticulous calibration to ensure precise and repeatable measurements across varying operational conditions—critical for ongoing process reliability.

  1. IBR Testing and Compatibility

For gauges used in boiler systems, we follow strict Indian Boiler Regulation (IBR) testing procedures to ensure compliance and compatibility with high-pressure steam applications.

Customization and Quality Assurance

Our advanced facilities enable complete customization across all types of level gauges—Tubular, Reflex, and Transparent. We adapt designs based on client specifications—whether it’s a matter of material selection, connection type, gauge length, or pressure rating.

Every unit is rigorously tested in-house by a dedicated quality team, ensuring it meets stringent quality control benchmarks before dispatch.

Conclusion

At Thermal Instrument, we don’t just manufacture level gauges—we engineer reliability. Our in-house testing capabilities ensure that all our Direct Visual Level Gauges—Tubular, Reflex, and Transparent—are built for unmatched precision, safety, and performance.

When you choose us, you’re choosing trusted quality backed by certified testing, ensuring peace of mind in even the most critical applications.
