The 2551 Magmeter is a magnetic flow meter from Georg Fischer that can be set up to measure both unidirectional and bidirectional flow. Manufactured from corrosion resistant materials for long life and minimal maintenance the 2551 is easy to install using Signet pipe fittings and requires no calibration. The 2551 magnetic flow sensor outputs a 4 mA to 20 mA and can be connected to a PLC, chart recorders and SCADA telemetry systems. The 2551 magnetic flow sensor features empty pipe detection and has a built-in diagnostic with easy to interpret LEDs.• Blind 4 mA to 20 mA, digital\/frequency, relay output,• Accurate measurement even in dirty liquids,• Multi-language display menu available,• Bi-directional flow,• Installs into pipe sizes DN15 to DN900 (½ in to 36 in),• Corrosion resistant materials, PP or PVDF with SS, Hastelloy-C or Titanium,• Operating rate range 0.05 to 10 m\/s (0.15 to 33 ft\/s),• Patented Magmeter Technology,• No moving parts,• Empty pipe detection• Chemical Processing,• Landfill Leachate,• Commercial Pools, Spas and Aquariums,• Water and Wastewater Monitoring,• Metal Recovery,• HVAC,• Scrubber Control,• Industrial Water DistributionMedia Monitored = LiquidDevice Type = MagmeterMinimum Flow Rate = 0.05 m\/sMaximum Flow Rate = 10 m\/sSupply Voltage = 24 V dcPipe Diameter Range = 1\/2 - 4 inConnection Type = DN15 to DN 100 SocketMaximum Pressure = 10.3barMaterial = Polypropylene, Stainless SteelMinimum Media Temperature = 0 °C
