    and provides an end-to-end width that is identical to an ASME BPE 180 elbow. Sensor Detects Low Gas, Liquid Flows Well-suited to pulsing or periodic flows, these in-line flow sensors provide rapid response and can monitor changes as low as 5 ml/min (0.001 GPM). Solid state device has no moving
  • Controlling a Tank Filling Operation With Two Liquids for a Food Processor
    A large Midwest food processor needed a low-cost and reliable solution to accurately control the batches of oil and water pumped into mixing tanks for the manufacture of corn chips and potato chips. The oil and water supply lines for the different tanks have different diameters and are each metered

Either a magnetic or modulated carrier (RF) pickoff can be used to sense the rotation of the turbine rotor and provide an electrical output that is proportional to the flow rate. The RF pickoff extends the low flow
