Dwyer Series FLMG

Dwyer Instruments Series FLMGFlanged Electromagnetic Flow Sensor
No Moving Parts, Minimal Straight Pipe Requirement, Unobstructed Flow

The Series FLMG Flanged Electromagnetic Flow Sensor is a flanged electromagnetic flowmeter designed for use in 4 to 10" pipes in municipal or industrial water and wastewater applications. The FLMG has no moving parts and requires less frequent maintenance in applications where debris or sand is in the flow. It’s specially designed with electrodes that discourage fouling and requires little space between the meter and a pipe elbow. Rate and total indication are standard for both models. The included 20-foot power cable provides pulse output for use with a variety of displays and controllers for remote reading, data logging, pulse-to-analog conversion, and telemetry applications. This series also features backup battery power to provide auxiliary power during power failures.
ACCESSORIES
• Series BAT, Blind Analog Transmitter, converts pulse output to 4 to 20 mA analog output. Unit is loop powered, fits on the enclosure of the meter, and is field spannable.
• Series RTI, Rate Total Indicator, converts pulse output to 4 to 20mA analog output with local flow rate and totalization display. Unit is loop powered, fits on the enclosure of the meter, and provides a high/low flow alarm.
• Series PWD, Pulse Divider, for use with pacing electronic metering pumps. Unit divides the input frequency to any number from 1 to 9999 with the use of rotary switches to suit a number of metering pump inputs.
