Geometric Dimensioning and Tolerancing (GD&T) includes different types of tolerance such as position, concentricity, and profile.

• Position tolerance specifies the allowable deviation from the true position of a feature

• Concentricity tolerance controls the central axis of a cylindrical feature relative to a datum axis

• Profile tolerance defines a uniform boundary that a feature must lie within

A flowmeter measures the flow rate of a fluid or gas by detecting the velocity of the flow.

• Flowmeters can use various technologies such as ultrasonic, electromagnetic, thermal, or differential pressure.

• The flowmeter measures the velocity of the flow and calculates the flow rate based on the cross-sectional area of the pipe.

• Some flowmeters have a display that shows the flow rate in units such as liters per minute or cub

Polarization index is a measure of insulation resistance in high tension motor maintenance.

• Polarization index is calculated by dividing the insulation resistance at 10 minutes by the insulation resistance at 1 minute.

• A high polarization index value indicates good insulation condition, while a low value may indicate insulation degradation.

• Regular testing of polarization index helps in detecting insulation issues early a...read more
