FLS F3.80 OVAL GEAR FLOW SENSOR


The FLS Oval Gear Flow sensors F3.80 have been designed following the main industrial application requirements: high mechanical resistance and reliable performances.These sensors are suitable to measure a wide range of viscous solid-free liquids with a very high accuracy and repeatability. The sensors can be fixed to flexible or rigid pipes via 1/4” GAS threaded process connections. The construction materials, ECTFE (Halar®) or PP or Stainless steel, provide high strength and chemical resistance.
