5. Which of the following is applicable for the electromagnetic flow meter? Explanation: Electromagnetic flow meters don’t cause obstruction to flow and can be used for measurement in slurries.
Which of the following are not suitable with electromagnetic flow meter Mcq?
Explanation: Electromagnetic flow meters are insensitive to temperature, viscosity and density of a fluid.
Which of the following device is used for measuring EMF between electrodes?
Electromagnetic flow meters detect flow by using Faraday’s Law of induction. Inside an electromagnetic flow meter, there is an electromagnetic coil that generates a magnetic field, and electrodes that capture electromotive force(voltage).
Which of the following is measured by tachometer?
A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common.
Which of the following is correct for the ionization transducer?
Which of the following is correct for the ionization transducer? Explanation: Grid current and primary electrons are always held constant and variations in anode current are measured. 6. Cold cathode ionization vacuum gauges are more accurate than hot cathode ionization vacuum gauges.
What is an electric flow meter?
A flow meter is a piece of equipment used to measure the flow rate of solids, liquids, or gases. … Flow meters are also known as flow gauges, flow indicators, or liquid meters.
Which of the following meter is used for measuring flow of clean fluids only?
Turbine meters are an easy way to accurately measure liquid flow rates in clean, ideally self-lubricating fluids. Turbine meters are used for custody transfer applications in many applications in the petroleum and chemical industries.
What sensor is used in an electromagnetic type flow meters?
These mag flowmeters consist of a magnetic sensor fitting connected to an electronics type and are designed to give flow measurement readings for applications involving liquids with a minimum conductivity of 5 μS/cm.
How does electromagnetic flow meters work?
How does a magnetic flow meter work? Magnetic flow meters use a magnetic field to generate and channel liquid flow through a pipe. A voltage signal is created when a conductive liquid flows through the flowmeter’s magnetic field. The faster the flow of the fluid, the greater the voltage signal generated.
What is electromagnetic water meter?
Electromagnetic Flow Meters, simply known as mag flow meter is a volumetric flow meter which is ideally used for waste water applications and other applications that experience low pressure drop and with appropriate liquid conductivity required. … Mag flow meters are also easy to maintain.
Which of the following quantities are sensitive to electromechanical flow meter?
6. Which of the following quantities are sensitive to electromechanical flow meters? Explanation: Electromagnetic flow meters are insensitive to quantities like viscosity, density, and temperature of liquid etc. 7.
Which of the following instrument is used to measure humidity?
A hygrometer is an instrument used to measure relative humidity. A psychrometer is an example of a hygrometer. A psychrometer uses two thermometers to measure relative humidity, one measures the dry-bulb temperature, and the other measures the wet-bulb temperature.
Which of the following can be used for measuring temperature?
Thermometer is used to measure temperature.
Which of the following is correct for load cell?
Which of the following conversion is correct for load cell? Explanation: Commonly load cell measure applied force using strain gauges, but in some cases, force is measured by detecting displacement, that is a force to displacement conversion. 7. Diaphragm element can also be used for force measurement.
Which of the following represent obstruction type flow measuring system?
Which of the following represents obstruction type flow measuring systems? Explanation: In such systems, flow rate is measured by making an obstruction in the path of flow. 7. Static vane system causes pressure loss in flow.
Which of the following devices can be used for measuring torque?
Explanation: Dynamometers are the devices which are used to measure torque in rotating parts of machines, mainly torque of rotating shafts.
