GENERAL INFORMATION 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 measuring 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.
INSTALLATION and OPERATION INSTALLATION CONNECTIONS Mounting. Mount the display housing to a secure surface with screws or bolts. Remove the front cover to gain access to the mounting holes, directly under the front cover screws. Attach the flow meter to a secure surface using the foot bracket. Alternatively, the unit can be supported by the piping and the foot bracket removed. See mounting diagrams below. The meter ships with the coil activation and signal leads already connected to the display housing.
