Flow Technology, Inc. (FTI), a leading manufacturer of precision flow measurement instruments, systems and calibrators, today announced the introduction of the Extended Linearity (EL) 500 Series of electromagnetic flow meters. Available in line sizes from 1/8 to 3/4 inch, these meters represent the state-of-the-art for accurate low flow rate measurement in a wide range of applications.

The latest in a new line of electromagnetic flow meters, the EL 500 Series creates a unique electromagnetic field profile ensuring accuracy not only in turbulent flow, but also during the transitional and laminar flow regimes. These compact meters provide extended linearity and a wide measurement range of up to 1000:1 without the aid of linearization software. The EL 500 has a bi-directional flow capability with no moving parts and no pressure drop. The meters cover the temperature range -4 to 320° F.

The EL 500 Series electromagnetic flow meters base their operation on the Faraday Principle, by which a conductor crossing a magnetic field generates a potential. The resultant potential is directly proportional to the flow velocity. The meters utilize a 316 stainless steel flow tube with AISI 316 UNI 338 male-threaded, NPT or tri-clamp/ISO 2852 fittings. Connections can be supplied in Hastelloy C or Titanium options. The standard liner material is PTFE. The flow meter enclosure is stainless steel.

Electronics available for the EL 500 series consists of a base transmitter with optional panel mounted display, as well as a multiple output converter with integral display. Electronics can be mounted directly on the flow meter or remotely mounted. When the electronics are remotely mounted the entire flow meter meets IP 68 suitable for permanent immersion in water up to a depth of 1.5 meters. A batching capability is also provided with MC 308C electronics.
