A gauge is an instrument used to measure, indicate, or compare a physical quantity such as pressure, level, thickness, or diameter.
In engineering and manufacturing, gauges help ensure accuracy, safety, and quality control.
Types of Gauges
Measure fluid pressure inside pipelines, tanks, and systems.
Example: Bourdon Tube Gauge (most common), digital pressure gauge.
Used in boilers, pumps, hydraulic systems.
Measure temperature of fluids, surfaces, or systems.
Types: Mercury-in-glass, Bimetallic strip, Digital sensors.
Used in engines, HVAC, and process industries.
Show liquid level inside tanks and vessels.
Types: Sight glass, Magnetic level gauge, Ultrasonic gauge.
Measure the rate of flow of liquids or gases.
Examples: Rotameter, Turbine flow meter.
Measures length, diameter, and depth with precision (0.02 mm).
Measures very small dimensions (0.01 mm accuracy).
Used for shafts, wires, thin sheets.
Measures small deviations in alignment, flatness, or roundness.
A set of thin blades used to measure small gaps or clearance between parts.
Used to check hole diameter (Go & No-Go type).
Used to check external diameter of shafts.
Quickly checks shaft diameters or thickness.
Measures pitch and angle of screw threads.
