A diaphragm pressure gauge is a type of pressure measuring instrument that is designed to measure the pressure of gases or liquids. It is one of the most commonly used types of pressure gauges and is widely used in various industries, including chemical, petrochemical, pharmaceutical, and food processing.

Diaphragm Gauge: How It Works

A diaphragm gauge is a type of diaphragm pressure gauge that uses a flexible diaphragm to measure pressure. The diaphragm is connected to a linkage system that is attached to a pointer, which moves over a scale to indicate the pressure. The diaphragm gauge is known for its high accuracy and is often used in applications where high precision is required.

Diaphragm Manometer: A Versatile Instrument

A diaphragm manometer is another type of diaphragm pressure gauge that is used to measure the pressure difference between two points. It consists of a U-shaped tube that is partially filled with a liquid, such as mercury or oil. The liquid level in the tube is used to measure the pressure difference between the two points. The diaphragm manometer is a versatile instrument that can be used in a wide range of applications, including fluid dynamics and engineering.

In conclusion, the diaphragm pressure gauge is an essential instrument for accurate pressure measurement. Its versatility, high accuracy, and ease of use make it a popular choice in various industries. Whether you need to measure the pressure of a gas or liquid, or the pressure difference between two points, a diaphragm pressure gauge is the ideal instrument for the job.
