Seametrics EM 101 v.2 - Manual (Page 3)

Page 1
The EM101 is a small electromagnetic low-flow flowmeter with
chemically-resistant plastic wetted parts and platinum electrodes
suitable for use with a variety of chemicals. Capable of measur-
ing pulsating flows from diaphragm-type metering pumps, it is
designed primarily for electrically-conductive chemical injection
applications. The 1/4” and 3/8” sizes monitor 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 EM101 is 115 Vac, 60 Hz powered and includes a rate and
total display as well as a variety of outputs. For continuous trans-
mission of a flow signal, there is a 4-20 mA output, a 0-5 volt signal,
and a frequency signal proportional to flow. In addition, there are
relay alarm outputs for user-set low and high flow levels.
