Battery powered electromagnetic flow-meter (EMF)
AG702 Seametrics Inc.

The AG702 is a tube-type electromagnetic flowmeter for use in irrigation applications in 6" and 8" pipe. With no moving parts, these meters are resistant to wear and there are no bearings or propellers to wear out.

The standard AG702 is battery powered. Where an external power source is available, the AG702 can be optionally converted to 7-32 Vdc, with the batteries then serving to maintain continuous operation in case of power failure.

The meter comes with built-in pulse output (requires optional output cable) for data logging or telemetry. Several pulse rates are available. An internal data logger is also available for secure flow logging (-127). A Seametrics FT420W indicator can be added if remote rate/total reading is desired, or an AO55W if a 4-20 mA (analog) signal is required.

The AG702 has a seal wire to protect against unauthorized access. The optional cable can be factory- or field-installed for applications where external power is available and/or pulse
output is needed.

In fertigation applications, the meter should be installed upstream of the chemical injection point or enough downstream to allow thorough mixing of fluids ahead of the meter (see Tech Bulletin on Seametrics website Downloads page).
