What is the flow measurement?

flow measurement is the practice of determining the amount of material flowing through a specified system, usually a pipe or channel. This is usually done with an inline flow meter. The flow measurement is widely used in applications from chemical plants to commercial air conditioning systems. The type of flow meter required for any particular application will depend on the properties of the measured substance. Measurement of the substance flow can be as simple as measuring the level of the process tank or complicated as measurement of induced voltage through the conductive fluid moving in the magnetic field. Although flow measurement usually refers to material in pipes or canaries, it may also refer to the flow of solids or material flow using systems such as traffic grids or rivers. Mocking gas or liquid flow requires the use of a flow meter. There are many types of flow meters, including holes, meters of turbine, Venturi meters, ultrasonic meters and electromagnetic flow meters to make JMThey entered at least some. In most chemical processes, the meters of opening are the most popular type of flow meters due to their simplicity and low costs.

The

verturi hole meters and the Venturi meter work on Bernoulli's principle, or more specifically the relationship between the material flow and the pressure drop that the material experiences through the meter. Turbine meters correlate the number of rotations that the inner turbine makes at the set time on the fluid flow through the blades. Fladay's electromagnetic meters are used by Faraday's law to correlate fluid velocity with induced voltage on the magnetic field in the liquid.

All these livestons of flow measurement may be subject to restrictions depending on the nature of the measured fluid. For example, an electromagnetic flow meter will only operate on an electrically conductive liquid. Meters that have moving parts such as meters of turbines are not recommended for abrasive or corrosive MATerials. Unusual systems may require unique or hybrid meters and calculations.

Calculated flow measurements can be improved using correction or compensatory factors. These factors are often used to compensate for temperatures, pressures and molecular weights, which differ significantly from the structural base of the fluid flow. Compensation factors are often used in the calculations of the distributed control system (DCS) in the chemical process settings.
