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.

Extended linearity 500 electromagnetic flowmeters
Extended linearity (EL) 500 electromagnetic flowmeters create a unique electromagnetic field profile to ensure accuracy in turbulent, laminar and transitional flows. They operate based on the Faraday principle, by which a conductor crossing a mag-netic field generates a potential, which is directly proportional to the flow velocity. Available in line sizes from 1/8 in. to 3/4 in., these compact meters have a wide measurement range of up to 1000:1 without the aid of linearization software. The EL 500 has a bidirectional flow capability with no moving parts and no pressure drop. The meters cover the temperature range of –4_F to 320_F. They utilize a 316 stainless steel flow tube with AISI 316 UNI 338 male-threaded, NPT or ISO 2852 fittings. Optional connections can be made of Hastelloy C or titanium. The standard liner material is polytetrafluoroethylene (PTFE) and the enclosure is stainless steel. Electronics can be mounted directly on the flowmeter, or to meet the IP 68 standard for permanent immersion in water up to a depth of 4.9 ft, they can be remotely mounted.
