Economical Flowmeters
Model PG-1000 Series (50mm)

Description

The PG-1000 Series Flowmeters are designed to allow reliable flow indication of gases at low capacities, while maintaining a rugged, economical plastic construction. A glass metering tube assures dependable, accurate performance throughout the meter's capacity range.

The PG-1000 Series flowmeters are direct reading for air, and are available in either English or Metric units. Choose between a black glass or stainless steel float.

The superior construction features of the PG-1000 Series Flowmeters result in a sturdy design with optimum gas metering characteristics. Complete annealing during production ensures each meter body is stress free. Threadless plastic blocks eliminate crazing and fracture, and the metal support frame absorbs all connection strain.

The glass metering tube is sealed directly into the acrylic body by means of a spring-loaded O-ring, and is interchangeable. The scale is permanently fused on the metering tube, close to the flow area, to reduce parallax and improve readout.

Design Features
  • Precision tapered glass metering tube
  • Aluminum frame absorbs connection strain
  • Reduced scale parallax
  • Removable tube for capacity change
  • Full 50mm scale length
  • Low end flow measurement of 0.06 SCFH
  • 10 to 1 or greater meter range
  • Low pressure drop
  • Meter support frame flanges allow variety of panel mounting positions
  • Control valve available installed at inlet or outlet
