GENERAL INFORMATION

The EM101 is a small electromagnetic low-flow flowmeter with
chemically-resistant plastic wetted parts and platinum elec-
trodes suitable for use with a variety of chemicals. Capable
of measuring pulsating flows from diaphragm-type metering
pumps, it is designed primarily for electrically-conductive chemi-
cal 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

The EM101 is 115 Vac, 60 Hz powered and includes a rate
and total display as well as a variety of outputs. For continu-
ous transmission 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.
