A direct mounting pressure gauge is a type of pressure measuring instrument that is directly connected to the pressure source without the use of additional tubing or a siphon. The gauge is typically installed onto the pressure port of a pipeline, vessel, or system, allowing it to measure the internal pressure directly. This mounting method is common in applications where quick and accurate pressure readings are needed and where the pressure source is accessible.

Here are the key features and aspects of direct mounting pressure gauges:

1. Mounting

• Direct Connection: The gauge is directly screwed into the pressure source (e.g., a pipe, valve, or tank) via a threaded connection (often a 1/4″ or 1/2″ NPT fitting).
• No Intermediate Components: Unlike remote-mounted gauges that use capillary tubes or hoses, direct mounting eliminates the need for additional components.

2. Applications

• Common Usage: These gauges are widely used in industrial settings, including HVAC systems, pumps, compressors, and fluid systems, where the pressure source is easily accessible.
• Ideal for Small to Medium Pressures: Direct mounting pressure gauges are suitable for measuring pressure in systems with relatively stable and moderate pressure levels.

3. Accuracy and Readings

• Direct Measurement: The pressure reading is immediate, providing real-time data without any delays that might occur with remote connections.
• Dial Face or Digital: Direct mounting gauges may have either analog dials with a needle or digital displays that show the pressure reading.
