ISOIL ISOMAG is a full range of electromagnetic flow meters from DN3 to DN2000 and pressure up to 250 bar. They are available in compact or separate version, wafer (up to DN400) or flanged mounting, with a wide range of options for electrodes and lining materials. The ISOMAG range includes sanitary design 3A certified for food applications, or WRAS approved material for drinking water applications. ISOMAG flow meters are MID001 and MID004 and OIML R49-1 certified making them suitable for custody transfer purpose. A range of insertion flow meters allow installation and removal from the pipe while under pressure.
The measurement of magnetic flow meters is based on electromagnetic induction. In a magnetic flowmeter, electromagnets placed above and below the meter create a magnetic field between them. As an electrically conductive substance flows through the magnetic field, a voltage is generated between the electrodes placed on both sides of the tube. The resulting voltage is directly proportional to the average flow rate of the substance. The electronics of the magnetic flowmeter convert the voltage into an output signal. Due to its operating principle, the magnetic flowmeter is only suitable for electrically conductive fluids such as water and various chemicals.
