The level of liquid under pressure can be determined using

• bubbler system

• differential pressure manometer

• diaphragm box system

• air-trap system

Dipsticks are used for the:

• Pressure measurement

• Flow Measurement

• Displacement Measurement

• Level Measurement

The most common application of float system is

• To monitor the fuel tank level in motor vehicle

• To monitor the flow of solid

• To monitor the flow of liquid

• All of these

Capacitive devices are used for the level measurement of

• only liquid

• Solid in powdered form

• Both a and b

• None of these

In Ultrasonic level gauge ,the ultrasonic source is placed at the

• Bottom of the vessel containing the liquid

• Top of the vessel containing the liquid

• Middle of the vessel containing the liquid

• Far from the vessel containing the liquid

In radiation methods , the detector system is located at

• The top of the liquid filled tank

• The bottom of the liquid filled tank

• Middle of the liquid filled tank

• Outside a liquid filled tank

A vibrating level sensors consists of

• One piezoelectric oscillators

• Two piezoelectric oscillators

• Three piezoelectric oscillators

• Four piezoelectric oscillators

Instrument which is capable of discriminating temperature differences of even 0.1 degree Celsius is,

• Fibre-optic level sensors

• Laser method

• Thermography

• Vibrating level sensors

In fibre-optic level sensors, the amount of light loss depends on

• the proportion of cable that is submerged in the liquid

• amount of light which is reflected back

• the proportion of cable that is not in the liquid

• amount of light which is not reflected back

Which of the following level measurement technologies cannot be adapted to measure solid level in vessel?

• Displacer

• Float and tape

• Radar

• Ultrasonic
