Irrigation Magmeter ; Electromagnetic Flow Meter

The AG2000 is a spool-type electromagnetic flowmeter for use in irrigation applications in 4” to 10” pipe. With no moving parts, these meters have unobstructed flow and are resistant to wear from debris found in ground or surface water. There are no bearings or propeller to wear out. Minimal straight pipe requirements allow AG2000 flow meters to be used in piping configurations where there is little space between the flow meters and an elbow.

In chemigation applications, the flow 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).

The standard electromagnetic flow meter AG2000 is battery powered.  Where an external power source is available, the Magmeter AG2000 can be optionally converted to 7-26 Vdc, with the batteries then serving to maintain continuous operation in case of power failure. This configuration will prolong battery life indefinitely.

The Electromagnetic flow meter comes with built-in pulse output (requires optional output cabling) 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 Magmeter AG2000 has a seal wire to protect against unauthorized access. The seal can be broken to change units of measure, replace the battery pack, or to field-install a power/output cable. The optional cable can be factory- or field-installed for applications where external power is available and/or pulse output is needed. The accessory weather guard is recommended in outdoor applications.

Low Flow Magmeter

The PE102 magmeter is designed for low-flow chemical injection or difficult-to-meter applications with pulsating metering pumps in 3/4” to 1/4” pipe/tube. The housing is made of sturdy splashproof HDPE plastic.

With no moving parts, the PE102 can handle fluids containing particulate matter without clogging or jamming, keeping maintenance at a minimum. With no metallic parts (100% PVDF body and PVDF carbon fiber-filled electrodes), the meter is corrosion-resistant and compatible with a wide range of chemicals. Accuracy is maintained with conductive fluids (>20 microSiemens) of varying viscosities and densities.

FEATURES

• No moving parts

• Requires no straight pipe

• Pulse and/or 4-20 mA output

• Chemical and corrosion resistant

• Insensitive to fluid density and fluid viscosity changes

APPLICATIONS

• Chemical injection

• Corrosive materials

• Low flow applications

• Pulsating flows (e.g., metering pump)

The PE meter is compact enough to fit most pump/injection systems. With zero straight pipe required after an elbow, it can be easily mounted in tight spaces. The mounting bracket adds stability. 

The PE meter has optocoupled current sinking or current sourcing pulse output that can be connected to the Seametrics FT420 rate/total display or FT520 batch processor, as well as a 4-20 mA loop for powering analog devices. Outputs and power are provided through a cable with 8-pin female circular connector.

EX100/200		Downloads
	The complete lack of moving parts of the EX100/200-Series insertion flow sensor is the source of its reliability. Brass and stainless steel models withstand a variety of temperature, pressure, and chemical conditions. The EX-Series has no rotor to stop turning in dirty water and there are no bearings to wear out.
