Question

the pressure measured with the help of a pressure gauge is called?​

Answer 1

Answer:

"gauge pressure"

Step-by-step explanation:

Instruments used to measure and display pressure in an integral unit are called pressure meters or pressure gauges or vacuum gauges. Most gauges measure pressure relative to atmospheric pressure as the zero point, so this form of reading is simply referred to as "gauge pressure".

Answer 2

The pressure measured by a pressure gauge is called gauge pressure.

Step-by-step explanation:

There are three types of pressures:

1. Absolute pressure: The pressure relative to vacuum.
2. Gauge pressure: Gauge pressure is pressure relative to the atmospheric pressure. This form of pressure is positive when it is above atmospheric pressure and negative when it is below atmospheric pressure.
3. Differential pressure: Differential pressure measurement is measuring the difference between two types of applied pressure. This form of pressure measurement does not have a reference but measures the two applied pressures.

A pressure gauge measures gauge pressure.

• It is a measuring instrument used to measure the level of pressure in a liquid or gas, across industries particularly in power, refineries, chemical, petrochemical, pharmaceutical, food, refrigeration, air-conditioning and sanitation industries.

• A pressure gauge measures fluid, gas, water, or steam intensity in a pressure powered machine to ensure there are no leaks or pressure changes that would affect the performance of the system.

• Pressure systems are designed to operate within a specific pressure range

• All pressure gauges have their own sensing element, which senses the value of the measured quantity.

Types of pressure gauge:

1. Hydrostatic Pressure: Hydrostatic pressure is generated by the weight of a liquid above a measurement point when the liquid is at rest. The height of the liquid influences the hydrostatic pressure.
2. Mechanical Pressure: Mechanical pressure is measured by a bellows, diaphragm, or Bourdon tube that converts fluid pressure into force.

Example of pressure gauge:

Manometer pressure gauge

• Manometer pressure gauges measure pressure on a fluid by balancing one column of fluid against a second column of fluid.

• This type of pressure gauge is the simplest type and consists of a transparent tube in the form of a "U" that is partially filled with a manometric fluid like mercury.

• In its simplest form, one end of the tube is connected to the location in which pressure is to be measured, while the other end is open to the atmosphere.
