Model AG2000 - Spool Type Electromagnetic Irrigation Flowmeter



The AG2000 is a spool-type electromagnetic flowmeter for use in irrigation applications in 3' to 12' pipe. With no moving parts, these meters provide unobstructed flow and are resistant to wear from debris found in ground or surface water. Little maintenance is required because there are no bearings to wear out or propellers to stop turning. Minimal straight pipe requirements allow AG2000 meters to be used in piping configurations where there is little space between the meter and an elbow.

The standard AG2000 is battery powered. Where an external power source is available, the AG2000 can be optionally converted to 8-32 Vdc. with the batteries then serving as backup to maintain continuous operation in case of power failure. This configuration will prolong battery life indefinitely.
An IP68 version (-168 option) is available for burial or applications where the meter may be under water up to a depth of 3 meters for prolonged periods of time.

The meter comes with built-in pulse output (requires optional cable) for data logging or telemetry. Several pulse rates are available. An internal data logger is also available for secure flow logging (-127 option). A Seametrics FT415W or FT420W display can be added if remote rate/total reading is desired. or an A055W if a (4-20 mA) analog signal is required. (High-frequency pulse rate is required for use with most Seametrics controllers.)
The AG2000 is secured with a seal wire to protect against unauthorized access. The seal can be broken by an authorized agent to change units of measure, replace the battery pack, or to field-install an optional power/output cable. The cable can be factory or field-installed where external power is available and/or pulse output is needed. An accessory weather guard is available for additional protection in outdoor applications. For chemigation applications, the chemical injection point must be placed downstream of the meter OR far enough upstream for complete mixing to occur before the flow reaches the meter.
