TEF Water Series Electromagnetic Flowmeter

TEF Water Series Electromagnetic Flowmeter

TEF Series flowmeter is a Faraday’s law based electromagnetic flowmeter, which measures the volumetric flowrate of conductive fluids. TEF has compact and remote (field) version and customers could choose each of them according to their applications. With the FLASH integrated, 32-bit ultra-low power MCU, the product shows a perfect performance of integration, operation and calculation, thus make the measurement stable, reliable and unaffected by flow patterns. TEF is widely used for flow measurement of conductive liquid in Chemical, Oil & Gas, Water & Waste Water, Metal, Textile, Paper & Pulp, Life Sciences, Food & Beverage, Environmental Protection, Power & Energy, and other process industries.

Features

  • No Moving Parts Long-Term Stability
