1. Installation Location: The pressure gauge should be installed in an easily visible location with adequate lighting. It should also be protected from direct exposure to radiant heat, low temperatures, and vibration.
2. Installation Angle: If the pressure gauge is installed at a higher location, it should be tilted slightly forward, but the angle should not exceed 30° to ensure accurate readings.
3. Pipe Connection: The pressure gauge pipe should be connected directly to the vessel to ensure accurate measurements.
4. Three-way Stopcock: To facilitate removal and calibration of the pressure gauge, a three-way stopcock should be installed between the pressure gauge and the vessel. The stopcock should be installed on a vertical pipe section and clearly marked to indicate it is open.
5. Water Trap and Isolation and Buffer Device: For steam vessels, a water trap should be installed between the pressure gauge and the vessel. For vessels containing high-temperature, highly corrosive, or condensable media, an isolation and buffer device should be installed.
