Dharvi Instruments Pvt. Ltd. offers a precision-engineered range of U-Tube Manometers, designed for accurate measurement of low differential pressures in air, gas, and liquid systems. These simple yet highly reliable instruments are widely used for laboratory, industrial, and HVAC applications where visual indication of pressure, vacuum, or differential pressure is required.
Operating on the basic principle of balancing a liquid column against the pressure to be measured, the U-Tube Manometer provides direct and instantaneous readings without the need for external power or complex electronics. Its transparent tube and clear scale markings ensure easy readability and dependable performance over a wide range of pressures.
Key FeaturesSimple and Reliable Design: Based on the time-tested liquid column principle — no moving parts, ensuring long operational life.
High Accuracy: Provides precise differential pressure readings with excellent repeatability.
Clear Visibility: Transparent glass or acrylic tube with engraved scale for direct and easy reading.
Corrosion Resistant: Wetted parts available in brass, stainless steel, or PVC for compatibility with various fluids.
Flexible Mounting Options: Can be wall-mounted, panel-mounted, or bench-mounted as per application.
Versatile Media Compatibility: Suitable for air, gases, and compatible process fluids.
Custom Scales & Units: Available in mmWC, inches of water, mbar, or custom engineering units.

Dharvi Instruments Pvt. Ltd. offers a precision range of Inclined Tube Manometers, designed for highly accurate measurement of low differential pressures in gases and liquids. Ideal for laboratory, industrial, and HVAC applications, these instruments provide enhanced sensitivity over standard U-tube manometers, making them suitable for low-pressure measurement and calibration tasks.
The Inclined Tube Manometer consists of a transparent inclined tube partially filled with a manometric fluid. The slope of the tube increases the scale length for a given pressure difference, allowing fine resolution and more precise readings. Its compact, robust design ensures reliable operation and long-term stability in critical process environments.
Key FeaturesHigh Sensitivity & Accuracy: Inclined design allows precise measurement of very low differential pressures.
Clear Visibility: Transparent glass or acrylic tube with engraved or printed scale provides easy and direct reading.
Corrosion-Resistant Construction: Tube and frame materials available in SS304, SS316, PVC, PP, or acrylic for compatibility with different fluids.
Maintenance-Free: No moving parts or electrical components, ensuring long-term reliability.
Flexible Mounting Options: Wall-mounted, panel-mounted, or bench-mounted as per application.
Versatile Fluid Compatibility: Suitable for air, gas, or low-pressure liquid measurements.
Custom Scale & Units: Graduations available in mmWC, Inches WC, mbar, Pa, or user-specific engineering units.
Optional Accessories: Valves, connectors, protective covers, and mounting brackets for ease of installation.
Type: Inclined Tube Manometer (Low Differential Pressure)
Tube Material: Borosilicate Glass / Acrylic (Transparent)
Scale Material: Aluminum or Acrylic, engraved or printed in contrasting color
Frame Material: Mild Steel (Powder Coated) / Stainless Steel / Aluminum
Connection: Brass / SS304 / SS316 / PVC / PP fittings
Mounting: Wall, panel, or bench type
Measuring Range: 0–10 mmWC up to 0–500 mmWC (custom ranges available)
Accuracy: ±0.5% of Full Scale
Manometric Fluid: Water, mercury, or colored oil depending on application
Operating Pressure: Up to 5 bar (depending on tube and connections)
Operating Temperature: Up to 60°C standard
Scale Units: mmWC, Inches WC, Pa, mbar, or custom units
End Connections: ¼" or ½" BSP/NPT (customizable)
