Seametrics EM 100-102 v.2 - Manual (Page 2)

The EM100/102 are small electromagnetic low-flow flowmeters
with chemically-resistant plastic wetted parts and 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-conductive
chemical injection applications. The 1/4” and 3/8” sizes moni-
tor maximum flows of 1 and 3 gallons per minute (or 4 and 11
L/min), respectively. Barb or NPT fittings are available, and must
be designated at time of order.
The EM100 and EM102 are 12-24 Vdc powered. The EM100
comes with a standard pulse output, and the EM102 with stan-
dard pulse and analog outputs. All electronics are self-contained
in a single compact chemically-resistant 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.
