The FMG210/220/230 Series are small electromagnetic
low-flow flowmeters with chemically-resistant plastic wet-
ted parts and a choice of Hastelloy or platinum electrodes
suitable for use with a variety of chemicals. Capable of
measuring pulsating flows from diaphragm-type metering
pumps, they are designed primarily for electrically-conduc-
tive chemical injection applications. The 1/4”, 3/8”, and
1/2” sizes monitor maximum flows of 1, 3, and 8 gallons
per minute (or 4, 11, and 30 L/min), respectively. Barb or
NPT fittings are available.
The FMG210/220/230 Series are 12-24 Vdc powered and
come with standard pulse and analog outputs. All electron-
ics are self-contained in a single compact chemically-resis-
tant housing, well suited for OEM applications.
These meters are also appropriate for remote monitoring of
chemical volume or rate using a computer or a PLC.
