State-of-the-art electromagnetic (Mag) flow meters from a leading international manufacturer are being marketed in the Gulf by Abu Dhabi Supplies and Commercial Services Est.

The hi-tech Magnetoflow Mag meters from Badger Meter Inc are said to be perfect solutions for challenging metering applications in the water industry.

Whether it’s metering a tough raw water pump station, or monitoring a reclaimed water distribution line with a high level of solids in suspension, or ensuring the highest level of accuracy and performance in a high revenue-generating industrial plant, Magnetoflow flow meters are said to stand up to the challenge.

“Electromagnetic flow measurement has today become the standard in the industry, with the flexible amplifier technique providing non-intrusive flow measurement and free flow of fluids without pressure drops,” explains a company spokesman.

He continues: “The Magnetoflow meters ensure customers receive the highest revenue generation from their metering system, and the innovative meter reading technologies make data collection more accurate and efficient.

“Their applications in the industry are so large that it would make no sense to develop one single type. This would be excessive and far too expensive. Customers need a solution for each of their application, a solution combined with accuracy, display and output signals. This cannot be solved with different liners and a variety of connections. This is why the amplifier technique had to be modular and flexible in its development.” Tracing the development of Mag meters, the spokesman says: “The first Mag meter was built in 1939 by Father Bonaventura Thurlemann, who was living in the Engelberg monastery in Switzerland.

“A Swiss company recognised its advantages in the early 50s and asked the Batelle Institute to develop an electromagnetic flow meter, which has become the basis of almost all Mag meters sold today on the market.

“The first meters with pipe amplifier were sold in 1962 under the brand Magnetoflow. The breakthrough of this technology was combined with the research and development of electronics. The amplifier, based on microprocessor technology, is today the heart of the electromagnetic measurement principle.

“The measuring principle of magnetic inductive flow meters is based on Faraday’s Law of induction. Inductive flow meters are used wherever conventional flow meters are unsuitable due to the properties of liquids (aggressive, abrasive, viscous or large quantities of entrained solids).

“They are ideally suitable for liquids, sludges, pulps and pastes with a minimum conductivity of 0.5µs/cm.

“Applications range from heat metering flow measurement, flow metering in the chemical industry, water supply and wastewater treatment, sludge return, power plants to the food industry.”

“The advantages of the Magnetoflow meters are several. They are compact and robust, available as meter-mounted or remote-installed converter, can be used in horizontal or vertical installations, are easy to install and service, and field-programmable,” he says.

“They have low flow measurement of less than 0.03 m/s, an accuracy ± 0,25% of actual value, a selectable pulse length, and are suitable for all liquids with a minimum of 0.5 µS/cm conductivity. Measurements are independent of pressure, viscosity, density and temperature.”

The meters come in sizes from DN 6 to DN 1400.
