The basic principle of a magnetic flow meter is based on Faraday's law of electromagnetic induction. It measures the flow rate of conductive fluids by generating a magnetic field across the flow tube. As the conductive fluid flows through this magnetic field, it induces a voltage proportional to the flow velocity, which is then measured and converted into a flow rate reading. This technology is non-invasive and works well with various fluid types, provided they have sufficient conductivity.
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.
it works on the electromagnetic principle the conductor cuts the magnetic field which produces induces emf for the flow of current
One of the easiest ways to detect a magnetic field is with a length of conductive material attached to a voltage meter. The presence of a magnetic field causes an electrical current to flow through the conductor, thus causing a spike on the meter.
The magnetic flow meter was invented by Hans Gottlieb Friedrich Woltman in the early 1950s. He developed this technology to measure the flow of conductive liquids using electromagnetic principles. The design has since undergone various improvements and adaptations, becoming a widely used instrument in various industries for its accuracy and reliability.
the basic principle on which a Venturimeter works is that by reducing the cross-sectional area of the flow passage, a pressure difference is created and by measuring this pressure difference, discharge through the pipe can be determined. formula to find actual discharge is=amount of fluid collected/time taken it works on the principle of bernoulli"s equation
The basic principle of the pressure tube log is to measure the pressure difference between two points along a tube to calculate fluid flow rate. By measuring the pressure at these points and knowing the fluid characteristics, the flow rate can be determined using a formula based on Bernoulli's principle.
An electromagnetic flow meter is a flowmeter which uses the electromagnetic technology to determine the amount of volume flow though a pipe. View the Related Links section for a link with a video about this.
A Venturi meter works based on the principle of Bernoulli's equation, which states that an increase in fluid velocity results in a decrease in pressure. The Venturi meter is a device that measures the flow rate of a fluid by creating a pressure difference between two points in a pipe, allowing for flow rate calculations based on this pressure difference.
Lenz's principle states that the direction of an induced electromotive force (emf) and the resulting current in a closed loop is such that it opposes the change in magnetic flux that produced it. This principle is a consequence of the conservation of energy and is commonly expressed in the context of electromagnetic induction. Essentially, if a magnetic field through a conductor changes, the induced current will flow in a direction that creates a magnetic field opposing that change. This principle is crucial in understanding how devices like generators and transformers operate.
THE SYMBOL FOR Flow Meter is : FI as Flow Indicator
A DC clamp meter works by measuring the magnetic field produced by the flow of direct current in a conductor. When the clamp is placed around the conductor, it detects the magnetic field and converts it into a direct current measurement. This measurement is then displayed on the meter's screen.
The above is the symbol of flow meter.
