Extended Linearity (EL) 2200 Series electromagnetic flowmeters

Representing state-of-the-art accurate flow measurement in water cycle and process applications, Extended Linearity (EL) 2200 Series electromagnetic flowmeters create unique electromagnetic field profiles to ensure accuracy in turbulent, transitional and laminar flow regimes. Without using linearization software, the meters can provide extended linearity and a measurement range of up to 1000:1. Featuring the ability to measure bi-directional flow, the EL 2200 series has no moving parts and no pressure drop. Based on the Faraday Principle, in which a conductor generates a potential by crossing a magnetic field, the potential is directly proportional to the flow velocity. The meters use a Type 304 stainless-steel flow tube with carbon or stainless flanges. Their sealed electrode and coil assembly provide immunity to humidity variation. A pair of Hastelloy C 22 electrodes generate the magnetic field, while a third functions as a ground. For one- to six-in. meter sizes, the meter uses PTFE as standard liner material. Larger sizes use Ebonite. Flange and sensor exterior surfaces are coated with acrylic paint, providing excellent resistance to water.
