Product Datasheet

Armor-FloTM meters with integral transmitters provide an ideal combination – a local mechanical flow rate indicator independent of electrical supply with a 4-20 mA two wire loop powered signal output. The output signal is linear within the middle 80% of the range. A response curve is furnished with each flowmeter. Simple design, rugged construction and good value make this the ideal utility fluid flowmeter.

  • Instantaneous local flow rate measurement.
  • Local flow rate indication requires no power.
  • Flow proportional signal output.
  • Broad range of materials available.
  • Use in horizontal or vertical piping systems.
  • Individually calibrated for fluid and operating conditions.
  • User selectable 10:1 turndown flow ranges. (“See Meter Rangeability Sizing Tables”)
  • User selectable units of measure-including dual units of measure.
  • No floats to get stuck, tubes to break or dynamic seals to leak.
  • Low pressure loss.
  • Simple design with few parts for long service life.

flex-flo-principal-operationsThe Armor-FloTM body housing has a variable internal volume which enlarges from the inlet to the outlet. The primary sensor is a tempered alloy vane with one end affixed to the apex of the meter housing. As the flow rate changes, the vane is flexed in direct proportion. A Teflon® encapsulated magnet links the vane position with the
pointer in the indicator housing and the signal output/switch circuit. All adjustments and electrical connections are accessible from the front of the meter housing.

The 1⁄2″, 3⁄4″ and 1″ connections typically have female threaded ends. Sizes 1 1⁄4″ through 12″ utilize an integral bypass housing permitting larger connection sizes in the format of a spool
with a consistant 12″ end to end dimension. In addition, it permits a wide variety of connection types which include threaded, flanged, grooved-ends and tri-clamp.
