Magnetic Flow Meters

pipe sections and those of substantial diameter.

The measurement of fluid flow is a common process control function. Flow measurement can have a range of differing output requirements, depending upon the needs of the process operators. With many technologies and instruments from which to choose, knowledge of the principals behind each measurement technology and basic operation requirements can help in the selection of the best instrument for each application. 

Anywhere there are pipes, somebody wants to know how much fluid is passing through them. Industrial flow meters rely on their ability to measure the change in some physical characteristic of fluid moving within a pipe that can be related to fluid velocity or mass flow. Depending upon the nature of the raw measurement, additional information and processing may be necessary to convert the base measurement into a useful measurement of flow rate.

In the processing industries, differing technologies are used to measure fluid motion. Some common technologies include magnetic, ultrasonic, vortex shedding, Coriolis and differential pressure. This list is not exhaustive, and several other technologies will certainly be found in use. Each methodology survives within a competitive marketplace due to its unique combination of performance and value attributes. Let's look at magnetic flow meters, also referred to as magmeters.

The operational principle of a magnetic flow meter is based upon Faraday’s Law. This fundamental scientific principle states that a voltage will be induced across a conductor moving at a right angle through a magnetic field, with the voltage being proportional to the velocity of the conductor. The principle allows for an inherently hard-to-measure aspect of a conductive fluid to be expressed via the magmeter. In a magmeter application, the instrument produces the magnetic field referred to in Faraday’s Law. The conductor, moving at a right angle to the magnetic field, is the fluid. The actual measurement of a magnetic flow meter is the induced voltage corresponding to fluid velocity. This can be used to determine volumetric flow and mass flow when combined with values of other fluid properties and the pipe cross sectional area. Magnetic flow meters enjoy some positive application attributes.

• Magnetic flow meters have no moving parts.
• The instrument, which often resembles a pipe section, can be lined with corrosion resistant material for use with aggressive media.
• With no sensor insertions or obstructions in the fluid path, the impact of the instrument on the flow is minimal.
• Accuracy, when compared to other technologies, is high.
• Application to laminar, turbulent, and transitional flow profiles is permissible.
• Generally, measurement is not adversely impacted by fluid viscosity, specific gravity, temperature and pressure.
• Magnetic flow meter technology can be applied to a very wide range of pipe sizes.
• Device responds rapidly to changes in fluid flow.
• Can be successfully applied to liquids containing heavy particulates.
• Generally long service life with little maintenance.

Though the roster of positive attributes is strong, magmeters are not universally applied. Consider some of these points with respect to your potential application.

• The fluid acts as the "conductor", as stated in Faraday's Law. Magnetic flow meters only work on liquids with conductivity above a certain threshold. They may be unsuitable for use with hydrocarbons and high purity water for this reason.
• Cannot be used to measure gas flow because gases are not sufficiently conductive.
• Piping must be grounded.
• Generally, rated accuracy requires the pipe cross section to be filled by the liquid being measured.

This listing of attributes is very general in nature. Some magnetic flow meter variants have adaptations that minimize or accommodate the impact of special process conditions.

Mass Flow Controllers for Precise Dosing

There are processing applications that require very accurate flow or dosing control of added constituents. The applications are diverse, ranging from controlled gas flow to precise metering of product fluid components. The ability to accurately and reliably measure and regulate mass flow of a fluid into a process is a common task in process measurement and control.

Thermal mass flow measurement, in basic operation, infers mass flow by measuring the heat dissipation from a heated temperature sensor and comparing it to an unheated reference temperature sensor. The heat dissipation is directly proportional to the mass flow of gas or liquid.

Thermal mass flow meters are very popular for several reasons. They have no moving parts, have a fairly unobstructed flow path, are accurate over a wide range of flow rates, calculate mass flow rather than volume, measure flow in large or small piping systems, and do not need temperature or pressure compensation.

For a process control application, accuracy and real time delivery of measurement data are key factors. Advanced smart controls with a range of communications options that will interface with a variety of devices across a choice of platforms bring high levels of functionality and ease of use to an application. For gas applications, smart technology allows one device to be applied to multiple gas types and ranges without removing the flow meter from the system. Product selection is enhanced by the availability of instruments targeted at a range of applications.

Level measurement of liquids and solids in containers, silos, tanks and other vessels is an essential part of many processing operations. Accurate and reliable measurement of solids or liquid level contributes to operational success, as well as enhancing safety, both of which contribute to the bottom line and successful operation.

Magnetrol, globally recognized innovator in flow and level measurement, incorporates years of experience into their latest version of non-contact radar level measuring instruments. The incremental improvements contribute to easier, more flexible installation and better performance.

The R86 is a 26 GHz level transmitter applicable across a wide range of requirements in many industries. Benefits of the 26 GHz radar signal, with its smaller wavelength, are a smaller antenna and improved 1mm resolution. The narrower beam from the antenna makes positioning the transmitter less restrictive, with easier accommodation for vessel fixtures or geometry. Advanced on board diagnostics supplement the improved performance and deliver the information needed to maintain proper operation and process visualization. A broad range of antennas and mountings are available for the R86, accommodating various tank sizes, fittings, and temperatures
