AG3000 Flow Meter: Seametrics Flanged Agricultural Irrigation Probes
Quick Answer
Quick Answer: The AG3000 flow meter is a flanged electromagnetic meter for agricultural irrigation water. It fits pipe sizes from DN50 to DN300, handles dirt and sand without a strainer, and outputs pulse or 4-20 mA signals for pump control and water allocation. Silver Automation Instruments supplies this Seametrics flanged agricultural irrigation probe for farms and irrigation projects in Australia, Southeast Asia, Latin America, and the Middle East.
AG3000 Flow Meter for Agricultural Irrigation Water
Irrigation water is not clean. It carries sand, silt, fertilizer residue, and organic fibers. A mechanical meter wears down quickly. The AG3000 flow meter has no moving parts. The flanged body mounts directly in the main line and measures flow through the full bore. This design removes the rotor, bearing, and strainer failure points found in propeller meters.
We have seen this on customer sites many times. A sugarcane block in Thailand used a DN150 propeller meter. The shaft jammed during the second season. The farm replaced it with a Seametrics flanged agricultural irrigation probe. The pulse output now feeds the pump controller. Since then the only service task is checking the cable connection once a month.
The AG3000 covers the main pipe sizes in irrigation. DN50, DN80, DN100, DN150, DN200, DN250, and DN300 flanged connections are common. Working pressure up to 10 bar covers most pump stations. Water temperature up to 60 °C is acceptable. Output options include pulse and 4-20 mA. Pulse works for total flow logging. The 4-20 mA signal works for rate monitoring and pump control.
Field Power and Installation
Because irrigation sites are often far from clean mains power, power matters. The AG3000 flow meter can be configured with pulse output for many field telemetry units. If you need a battery powered configuration for remote bore water transfer or pivot irrigation, ask our engineers before ordering.
Here is the thing. Straight run matters. Use 5 pipe diameters upstream and 3 diameters downstream when possible. Most engineers skip this part. In practice, an elbow directly before the meter can disturb the flow profile. That causes a reading shift, not a total failure. We tell customers to install the meter after a straight section. If space is limited, a DN80 meter on a short run is still easier to install than a mechanical meter with a strainer.
Why This Beats Mechanical Irrigation Meters
Many irrigation districts still use propeller or turbine meters. Those meters need strainers and regular cleaning. The AG3000 flow met
The real cost of a flow meter includes labor, downtime, and spare parts. Mechanical meters often fail in the middle of a growing season. The AG3000 flow meter gives a steady signal for water allocation and pump control. That matters when irrigation blocks run 12 hours a day.

AG3000 Flow Meter FAQ
What pipe sizes can the AG3000 flow meter handle?
It is supplied in flanged sizes from DN50 to DN300. The most common sizes in irrigation are DN100, DN150, and DN200. Larger sizes suit main pump discharge lines. Smaller sizes suit block flow measurement.
Does the AG3000 work with sandy or silty water?
Yes. The full bore flow tube has no moving parts. Sand and silt pass through without jamming. The electrodes and liner are selected for irrigation water. A strainer is not required in most cases.
Can I get pulse output and 4-20 mA from the same meter?
It depends on the converter configuration. Many AG3000 flow meter models support pulse output as standard. A 4-20 mA output can be added for rate monitoring. Tell us your control panel input type before ordering. Our team will match the output to your pump controller or telemetry unit.
What information do you need for a quote?
Send pipe size in DN, pressure in bar, water temperature in °C, flow range in m3/h, and output type. Also include cable length from the meter to the panel. This lets us quote the right flanged agricultural irrigation probe without extra back and forth.
How long does delivery take?
Delivery depends on the flanged size and current stock. Common sizes like DN100 and DN150 are often faster. For projects in Australia, the Middle East, or Latin America, we confirm the lead time after we know the size and output configuration. Send us your location and we will confirm shipping.
