The SERIES MFS & MFS2 Electromagnetic Flow Transmitters is a compact, 316
SS body, in line flowmeter with pulse and optional analog 4 to 20 mA output. It is
available in a variety of flow ranges from 0.25 to 52.8 GPM (1 to 200 LPM) and process
connection sizes of 1/2˝ and 1˝ NPT.
FEATURES/BENEFITS
• Long life cycle with no moving parts to wear or break
• Can be applied in applications dealing with contaminated media with no mechanical
component in the flow
• Obstruction free pipe cross-section yields low pressure drop
• Unaffected by change in temperature, density, viscosity or concentration
APPLICATIONS
• Contaminated liquid flow monitoring
• Flow of conductive liquids
• Water & wastewater treatment
• Industrial systems
• Irrigation applications
