Plastic-Bodied Magmeter
* Will not read petroleum
based liquids.
The 1" Flow Meter Series are a full-bore, plastic-bodied electromagnetic
flow meter designed for flow and usage monitoring applications in 1" pipe.
The polypropylene flow tube offers corrosion resistance to a wide range of
chemicals. Its light weight and clamp flanges allow it to be easily installed
or removed from the pipe for inspection. There are multiple configurations.
With no moving parts, the magmeter permits unobstructed flow,
minimizing flow disturbances. The 1" Meter Series can be used in
piping configurations where there is little space between the meter
and valve. The 1" 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 flow stream, the meter tolerates high flows without
damage. Please note that flow does not automatically turn the meter on.
The hinged, polyethylene cover protects from dust and UV rays, while
permitting easy access to the LCD flow 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 1" Meter Series are used for tracking flow rates and total flow 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. In
the event of DC power loss, or when changing batteries, the flow meter
will retain internal settings and flow total.
The flow 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 flow meters are battery-operated units 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 flow meters shut off after minutes of inactivity to preserve battery life.

  • Page 5: Installation

    INSTALLATION Piping Conditions Installing the meter with a length of straight pipe at least two times the diameter upstream and one diameters downstream is highly recommended. Some piping conditions require more than this. See chart for recommendations. If hose is used, use smooth bore hose. Follow the diagram below to make the connections.
  • Page 6 POSITION This is an all position meter which can be installed either vertically or horizontally, register up, down or angled. However, entrained air or solids may make some positions preferable to others. See the position diagram for guidance. Electrode moved from top by rotating meter Intermittent air...
  • Page 7 STRAIGHT AND FULL PIPE RECOMMENDATIONS It is recommended to have at least 10 inches of straight pipe before the flow meter and at least 10 inches after.
