Pressure Gauges

---

Overview

Our pressure gauges are engineered for precise and reliable pressure monitoring in RO, UF, and industrial water systems. Built with heavy-duty stainless steel construction, these gauges are designed to perform under vibration, pulsation, and demanding operating conditions. Whether used on feed lines, membranes, or high-pressure pumps, Duvera gauges deliver stable, repeatable readings that safeguard plant performance and ensure operator confidence.

Key Features

Each pressure gauge is encased in 304 stainless steel for corrosion resistance and long-term durability. The bourdon-tube sensing mechanism provides smooth, accurate deflection even in dynamic pressure systems. A glycerin-filled case minimizes needle vibration and enhances readability under fluctuating load conditions. Clear, high-contrast dials ensure visibility from a distance, while options for bottom or rear mounting offer flexibility in installation. Designed for compatibility with oil, water, or other non-corrosive liquids, Duvera gauges maintain accuracy and integrity even in harsh service environments.

Applications

Duvera pressure gauges are widely used across feed and permeate lines of RO and UF plants, high-pressure pump discharge monitoring, filter differential measurement, and dosing systems. They are equally suited for use in industrial utilities, hydraulic circuits, and process pipelines where pressure stability and equipment protection are critical.

Specifications

Each unit features a 63 mm dial housed in a 304 stainless-steel case with glycerin filling for vibration damping. Pressure ranges are available from 10 kg/cm² to 21 kg/cm², with accuracy levels of ±1.0 %, ±1.6 %, or ±2.5 % FSD depending on diameter. Connection options include bottom or rear mounts in 1/8″, 1/4″, 3/8″, and 1/2″ BSP, BSPT, or NPT threads, manufactured from high-grade brass. The gauge is rated for a maximum process temperature of 60 °C and offers IP65 weather protection, ensuring reliable operation in indoor and outdoor installations.
