Which of the following are not suitable with electromagnetic flow meter? Explanation: Electromagnetic flow meter can be used with all type of liquid. Explanation: E= BDV, where B is the magnetic flux density, D is the diameter of the tube and V is the velocity of flow.
Where can you use a magnetic flow meter?
Magnetic flowmeters are used in water treatment plants to measure treated and untreated sewage, process water, water and chemicals. Mining and mineral process industry applications include process water and process slurry flows and heavy media flows.
What is the working principle of electromagnetic flow meter?
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).
What is electromagnetic blood flow meter?
Electromagnetic blood flowmeters and flow probes are used to measure blood flow in blood vessels throughout the circulatory system. The principle of this measuring device is based on laws of electromagnetic induction discovered in the 19th century.
Which of the following quantities are sensitive to electromagnetic flow meters?
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.
What is the difference between mass flow meter and magnetic flow meter?
Differences in Flow Measurement
In mass flow meters, the flow rate is calculated by measuring the amount of mass of a substance passing through a device for a given amount of time. In volumetric flow meters, the flow rate is calculated by measuring the volume of a substance through a device over a given period.
What are the different types of flow meters?
Types of Flow Meters
- Coriolis Meters.
- DP Meters.
- Magnetic Meters.
- Multiphase Meters.
- Turbine Meters.
- Ultrasonic Meters.
- Vortex Meters.
How is flow measured?
Introduction. Flow is the volume of fluid that passes in a unit of time. In water resources, flow is often measured in units of cubic feet per second (cfs), cubic meters per second (cms), gallons per minute (gpm), or other various units.
What is the function of rotameter?
A rotameter (variable area meter) is a flow meter that measures volumetric flow of liquids and gases. There is no difference between a rotameter and flow meter, and these terms are used interchangeably. The technique for measuring flow is accomplished by a freely moving float finding equilibrium in a tapered tube.
What is Coriolis principle for mass flow meter?
The operating principle of a Coriolis flow meter is basic but very effective. When a fluid (gas or liquid) passes through this tube the mass flow momentum will cause a change in the tube vibration, the tube will twist resulting in a phase shift. …
What is full bore magnetic flow meter?
Full bore electromagnetic flowmeter – Type 8056
The Type 8056 full bore flowmeter consists of a magnetic sensor fitting Type S056 connected to an electronics Type SE56. It too is designed for applications involving liquids with a minimum conductivity of 5 μS/cm. … Low-flow measurements on from 3 l/h.
How does a magnetic flow switch work?
A magnetic flow switch is best for water/liquid flow. It works by creating a magnetic field that the liquid can pass through. When the liquid goes through the magnetic field, it triggers an electrical sensor which will produce an action based on the flow rate.
What is unit for flow rate for gases?
Gas mass flow rate is the actual mass of a gas which moves through a measurement instrument per unit of time. Its units are usually in standard liters per minute (slpm) or standard cubic centimeters per minute (sccm) in SI units. The most common English units include standard cubic feet per minute (scfm).
Which of the following is correct for thermistors?
Which of the following is correct for thermistors? Explanation: For thermistors as temperature increase, resistance decreases.
Which of the following is correct for tactile sensors?
1. Which of the following is correct for tactile sensors? Explanation: Tactile sensors are those which sensitive to touch. Explanation: Sensitivity of a sensor is the change in output for a change in input.
