Dwyer Series IEF Insertion Electromagnetic Flow Transmitter

Model / series: IEF

The IEF is an insertion electromagnetic flow meter: one adjustable unit fits pipes from 4 to 36 inches, installed through a 1 in NPT or BSPT fitting, with an optional full-port ball valve. It measures clean or dirty conductive liquids with negligible pressure drop.
