Weiss Case Mount Gauge | 4CTS-1-100-4L-BR | 4″ Dial | 0-100 PSI/BAR
Product Description
The 4CTS-1-100-4L-BR features a high-visibility 4-inch (100 mm) dial and an integrated front flange for a clean, recessed look. According to Weiss nomenclature: “CTS” identifies the stainless steel case with a front flange, “100” is the pressure range, and “4L” indicates a 1/4″ NPT Lower (Bottom) Mount connection. The “BR” signifies the inclusion of precision brass internals.
With a dual scale of 0-100 PSI (0-7 BAR), this gauge is the standard choice for monitoring domestic water booster sets, irrigation headers, and filter differential panels in Dubai and Abu Dhabi. The 304 Stainless Steel housing ensures superior resistance to the humidity and corrosive coastal air common in the Middle East, while the oversized dial face allows for effortless monitoring across mechanical rooms.
Key Features
- Flush Panel Mounting: Integrated front flange allows for a professional and secure installation into control panels or machinery housings.
- Large 4″ High-Visibility Dial: Provides an oversized viewing area, ensuring pressure readings are clear and easy to read from a distance.
- Stainless Steel Durability: Constructed from 304 Stainless Steel for enhanced longevity and rust resistance in humid environments.
- Dual Scale (PSI/BAR): Displays pressure in both imperial and metric units, satisfying international project requirements in the UAE.
- Precision Brass internals: Utilizes a high-grade brass Bourdon tube and socket for consistent performance with water, air, and other non-corrosive media.

Frequently Asked Questions
- Q: Why use a Lower Mount (4L) for a panel gauge instead of a Back Mount?
- A: A bottom connection is often preferred when the internal panel piping is already routed below the instrument, or when a back connection would interfere with other components inside the enclosure.
- Q: Can this be used for residential water pressure?
- A: Yes, the 100 PSI range is perfect for residential booster sets, though the 4-inch dial is typically reserved for larger commercial panels.
- Q: Is this gauge liquid-filled?
- A: This model is a “Dry” gauge. If your system experiences heavy pump vibration, you should consult with us about a liquid-filled (LF) version to protect the movement.
