Omega Engineering FGM220 用户手册

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.
