Banjo MFM220 User Manual

The 2" Flow Meter Series are a full-bore, plastic-bodied electromagnetic
ow meter designed for ow and usage monitoring applications in 2" pipe.
The polypropylene ow tube oers corrosion resistance to a wide range of
chemicals. Its light weight and clamp anges allow it to be easily installed
or removed from the pipe for inspection. There are multiple congurations.
With no moving parts, the magmeter permits unobstructed ow,
minimizing ow disturbances. The 2" Meter Series can be used in
piping congurations where there is little space between the meter
and valve. The 2" Meter Series, like other magmeters, are resistant to
wear from debris. Since there are no bearings or propeller to wear out,
downtime and maintenance are kept to a minimum. Because there are no
mechanical parts in the ow stream, the meter tolerates high ows without
damage. Please note that ow does not automatically turn the meter on.
The hinged, polyethylene cover protects from dust and UV rays, while
permitting easy access to the LCD ow rate and total display. The
electronics housing is made of rugged powder-coated die-cast aluminum.
Flow rate and total can be displayed in a variety of units, customer-
selected and factory-set.
The 2" Meter Series are used for tracking ow rates and total ow in
usage monitoring applications. These would include wells, industrial
wastewater, leach mining discharge, cooling tower deduct metering, turf
and landscape applications, and other water reclamation operations.
When changing the batteries, the 2" is designed to retain the internal
settings and ow total.
The DC ow meters are externally powered via a 5-pin connector cable
(20ft/6m) which also provides pulse output for use with a variety of
displays and controls for remote reading, data logging, pulse-to-analog
conversion, and telemetry applications.
The standard ow meters are a battery-operated unit for use when
pulse output is not required. The batteries are user replaceable with an
approximate 1-year life under continuous use, or more depending on
the duty cycle. The ow meters shut o after 15 minutes of inactivity to
preserve battery life.
