EM100/102 EM100/102 LOW FLOW MAGNETIC FLOWMETER INSTRUCTIONS LOW FLOW MAGNETIC FLOWMETER INSTRUCTIONS
GENERAL INFORMATION The EM100/102 are small electromagnetic low-flow flowmeters 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, they are 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, CONNECTIONS, and OPERATION INSTALLATION Connections Mounting. The EM100/102 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. Power and signal connections are provided by the single 4- or 6-conductor color-coded cable. See the Connections chart, back page.
