GENERAL INFORMATION

The EM100 is a 24 VDC-powered electromagnetic flow meter with
chemically-resistant plastic wetted parts, in nominal maximum flow rates of
4, 11, and 30 liters per minute. It uses bipolar DC technology at a frequency
high enough to allow for measurement of pulsating flows from diaphragm-
type chemical metering pumps. All electronics are contained in a single
compact, chemical-resistant housing. This configuration, combined with the
standard pulse and analog outputs, makes the EM100 well suited for OEM
applications. Other applications include remote monitoring of chemical
volume or rate using a computer or PLC.
