There is a float in Mercury manometer.It positions the balls in nonmagnetic tube below it.The permenant magnet is self centering on the steel ball and two glass balls are used for additional buoyance.Movement of float prodeuces corresponding rotation of magnetic arm,and a pointer operates over and indicating scale.

What is a magnetic clutch switch?
its a clutch stuck to a switch and it can carry magnetic stuff near 1 meter away
Why is the orifice plate called a variable head flow meter?
Because it relies on the back pressure through a known orifice which its differential pressure across the plate relates to flow.
What is a servo regulator?
Fuel servos work the same for nearly all aircraft.They basically measure the airflow to generate a differential pressure on a set of diaphragms. The "differential" pressure is used to meter the fuel flow. As the airflow increases these baffles/diaphragms move which allows more fuel to flow. As the airflow decreases less fuel is allowed.
What is a differential meter?
A meter that measures the difference between two signals instead of measuring signals individually. It is vital that neither probe of a differential meter be internally grounded, whereas some types of ordinary meters might have or provide for grounding of the black probe.
What tool would you use to detect magnetic effects?
A magnetic needle meter, or a simple compass.
What is the equipment used to measure magnetic force called?
A magnetometer is used to measure magnetic force in magnetic fields.
Why pressure gauge is called a gauge not a meter?
Because Pressure gauge measures the the differenceof pressure so it is called pressure gauge not meter.
What is the principle of micromotion flow meter?
it principle denpend on what kind of flow meter. example, magnetic flow meter, it use magnetic force to measuring or coriolis flow meter which is use vibrated capilary tube as sensor. or more info you might watch on youtube.
What do you use to measure decibels?
You measure the sound pressure with a sound pressure level meter (SPL meter).
Unit of magnetism are?
The unit of magnetism are: Weber for magnetic flux, Tesla for magnetic flux density and ampere per meter for magnetic field strength.
Magnetic flux density is measured by q meter or ac voltmeter or hall probe or energy meter?
Hall Probe. When the Hall Probe is held so that the magnetic field lines are passing at right angles through the sensor of the probe, the meter gives a reading of the value of magnetic flux density (B).
How do you select the right flow meter for your application?
Flow meter categories based on fluid Some flow meters can be easily eliminated because they simply will not work with the application. For instance, electromagnetic flow meters will not work with hydrocarbons and require a conductive liquid to function. Many flow meters cannot measure gases or slurries. Listed below are some of the main flow meter categories paired with the fluid type the meters can handle. Gas – Coriolis Mass, Thermal Mass, Ultrasonic, Variable Area, Variable Differential Pressure, Positive Displacement, Turbine Liquid – Coriolis Mass, Thermal Mass, Ultrasonic, Variable Differential Pressure, Positive Displacement, Turbine, Electromagnetic Slurry – Coriolis Mass, some subsets of Variable Differential Pressure, Electromagnetic, Ultrasonic Vapour – Vortex, Ultrasonic, Diaphragm, Floating Element
