Product details
Weiss Liquid Filled Gauge | LF602-160 | 6″ Dial | 0-160 PSI/BAR
Product Description
The LF602-160 is engineered to perform where standard dry gauges fail. The gauge case is filled with Glycerin (or Silicone by request), which serves to dampen the internal movement and stabilize the pointer. This eliminates “needle flutter” caused by mechanical vibration or rapid pressure surges, ensuring accurate readings and extending the life of the instrument in demanding Dubai and Abu Dhabi plant rooms.
With a massive 6-inch (150 mm) dial and a dual-scale range of 0-160 PSI (0-11 BAR), this gauge provides unparalleled visibility from long distances. It is constructed with a corrosion-resistant 304 Stainless Steel case and features a 1/4″ NPT Lower (Bottom) Mount connection. This combination of size and durability makes it ideal for the main discharge lines of large-scale water booster sets and chilled water primary pumps.
Key Features
- Liquid Filled Dampening: Glycerin filling protects the movement from wear and provides a steady pointer reading in high-vibration applications.
- Oversized 6″ Dial: Offers maximum visibility, allowing for precise monitoring from across large mechanical plant rooms.
- 304 Stainless Steel Case: Provides superior resistance to the humid, saline air common in UAE coastal regions.
- Dual Scale (PSI/BAR): Displays pressure in both imperial and metric units, satisfying international project standards in the Middle East.
- Ventable Plug: Features a relief valve/fill plug to allow for internal pressure equalization, maintaining accuracy regardless of ambient temperature changes.

Frequently Asked Questions
- Q: Why use a 6-inch gauge instead of a 4-inch?
- A: In large district cooling plants or high-rise pump rooms, gauges are often mounted 3-4 meters high. The 6-inch dial ensures the reading is perfectly clear without the need for a ladder.
- Q: Is this gauge suitable for outdoor use?
- A: Yes, the combination of a stainless steel case and liquid filling makes it exceptionally resistant to the UAE’s outdoor elements and direct sunlight.
- Q: Can the liquid be drained?
- A: While it is designed to be liquid-filled, the glycerin can be drained if necessary; however, the vibration-dampening benefits will be lost.
