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.

MOUNTING The EM100 can be supported by its piping connections if the piping is rigid and there is no vibration. Alternatively, the grounding studs can be used for mounting by inserting them through pre-drilled holes. Note the centerline distance in the dimensional drawing below. CAUTION: Although this meter has an empty pipe detection function, under certain conditions of empty or partially-full pipe the meter may read a flow when there is none.
PAGE 3
AR CH IV ED If metal piping is used, ground connections from the grounding studs on the bottom of the unit to both inlet and outlet pipes provide the best results in metering accuracy. This does not apply to plastic tubing. A minimum of 1” of straight pipe run is recommended on the inlet side of the meter. Straight run is not necessary on the outlet.

OPERATION When the newly-installed meter is first powered up, particularly if it has been dry prior to start up, it can take from a few seconds to a minute for the signal to stabilize. In normal operation, keeping the meter filled with fluid is recommended to prevent this delay. An empty pipe detection feature will normally respond to lack of liquid in the pipe, and will register zero flow, but under certain rare conditions it is possible for this feature to fail to recognize the empty pipe.
