Weiss Utility Gauge | TL25-100-4L-BR | 2.5″ Dial | 0-100 PSI/BAR
Product Description
The TL25-100-4L-BR belongs to Weiss’s reliable TL Series, engineered for accuracy and longevity in environments where non-corrosive media is used. With a 2.5-inch (63 mm) dial and a range of 0-100 PSI (0-7 BAR), this gauge is a versatile choice for monitoring booster pumps, filter status, and domestic water pressure in Dubai and Abu Dhabi.
The “4L” in the model code specifies a 1/4″ NPT Lower (Bottom) Mount connection, while the “BR” indicates the inclusion of Brass internals (Bronze tube and Brass socket). Housed in a black-finished drawn steel case with a push-in polycarbonate window, this gauge is built to withstand the typical mechanical room conditions of the Middle East, offering a cost-effective and dependable pressure sensing solution.
Key Features
- Dual Scale Readout: Simultaneously displays pressure in PSI and BAR (or kPa/kgcm² depending on regional variant), meeting international engineering standards.
- Rugged Steel Case: Finished in black for corrosion resistance and durability in commercial plant rooms.
- ASME Grade B Accuracy: Meets $\pm$3-2-3% accuracy standards, ensuring reliable monitoring for routine maintenance.
- Precision Brass Movement: All-brass construction with precision gear and pinion mounted independently of the case for enhanced stability.
- Service Versatility: Intended for air, oil, water, and gas—any medium that does not attack brass components.

Frequently Asked Questions
- Q: What does the “4L” stand for in the model code?
- A: “4” refers to the 1/4″ NPT thread size, and “L” indicates the “Lower” or bottom mount position.
- Q: Can this gauge be used on a steam boiler?
- A: Only if protected by a coil-type siphon (pigtail) to prevent high-temperature steam from damaging the bronze/brass internal components.
- Q: Is this gauge suitable for irrigation systems in the UAE?
- A: Yes, it is excellent for irrigation manifolds where pressure typically remains below 100 PSI and the environment is sheltered.
