Radial Manometer, 0 - 10 bar, 100 mm

Product detailed description

This radial manometer is suitable for industrial and commercial applications where pressure monitoring is critical for system performance. Installers commonly use it in central heating systems, boiler houses, and pump stations to ensure safe and efficient operation. The large 100 mm dial allows operators to read pressure values quickly and accurately, even from a distance. Its steel construction ensures durability under normal working conditions and provides resistance to mechanical impacts during installation and operation.

Technical parameters

Installation and connection

Mounting should be carried out in accordance with the manufacturer’s guidelines, ensuring the manometer is positioned horizontally to maintain correct fluid levels within the internal mechanism. The 1/2 inch radial port requires a standard compression or threaded fitting, depending on the system design. Ensure that the mounting surface is stable and free from vibration to prevent false readings. Common installation errors include incorrect orientation, over-tightening of the connection, or neglecting to isolate the system before installation. Always verify that the pressure in the line does not exceed the maximum rated limit before connecting.

Compatibility and accessories

This manometer is compatible with low-pressure hydraulic and thermal systems using non-corrosive liquids. It can be integrated into existing heating systems or pump circuits without requiring additional components. For secure mounting, consider using a bracket or support frame depending on the location. No special accessories are required for standard operation. Ensure the system is designed for dry media and that the operating environment remains within typical indoor conditions. Related products may include isolation valves, pressure-reducing valves, or check valves for complete system integration.

Technical background for designers

The manometer operates on the principle of a Bourdon tube, which deforms under internal pressure and moves a pointer across the dial. The steel casing protects the internal mechanism while allowing visual inspection through the glass face. The device is designed for dry media only, meaning it should not be used with steam or vapour without additional protective measures. Long-term exposure to excessive vibration or temperature fluctuations may affect the accuracy and longevity of the instrument. Proper system sizing and isolation help extend the operational life and reduce maintenance requirements.

Service and operation

Periodic visual checks for cracks in the glass, leaks around the connection, or pointer misalignment are recommended. If the pointer does not return to zero after depressurisation, recalibration or replacement may be necessary. There are no specified service intervals in the technical documentation. In the event of suspected malfunction, disconnect the manometer from the system and inspect for physical damage or contamination. Avoid exposing the device to pressures beyond the stated range, as this can cause permanent deformation of the internal components.

Frequently asked questions

Can this manometer be mounted vertically?
Mounting vertically is not recommended, as the internal mechanism is designed for horizontal positioning to ensure accurate readings.

Is this suitable for steam systems?
This manometer is intended for dry media only and should not be used with steam or vapour without additional protection.

What happens if the pointer does not return to zero?
If the pointer fails to return to zero after depressurisation, the device may require recalibration or replacement.

How to check for correct installation?
After installation, ensure the system is isolated and depressurised. Check for leaks at the connection point and confirm that the pointer remains stable and returns to zero when no pressure is applied.
