Pneumatic Flow Meters, Air Compression Meters, Lake MonitorsFor 1/8"- 2" Pipe Sizes

Style Gce

Ideal for monitoring air compressor outputs, pneumatic tool consumption and industrial gas flows.

  • CHOICE OF THREE MATERIALS OF CONSTRUCTION
    Select from aluminum, brass or stainless steel to meet system and media compatibility requirements.

  • UNRESTRICTED MOUNTING
    Allows the designer to install the meter in any orientation – horizontal, vertical or inverted.

  • SUPERIOR EXTERIOR DESIGN
    Weather-tight for use outdoors and/or on systems where wash downs are required.

  • RUGGED AND RELIABLE
    These meters are constructed with all metal pressure vessels, allowing safe, permanent installation in industrial systems.

  • HIGH PRESSURE OPERATION
    The magnetically coupled follower and rigid pressure vessel design allows operation to 1000 PSIG.

  • 24 DIFFERENT PORTS AVAILABLE
    Standard selection of NPT, SAE and BSP ports reduces the amount of adapters required for installation.

  • LOW COST ACCURACY
    ±2.5% of range accuracy in center third of scale; ±4% in upper and lower thirds.


Engineering Specification

THE PNEUMATIC IN-LINE FLOW METER SHALL:

  • Use the variable annular orifice technique with compression spring recoil.

  • Not require inlet or outlet straight plumbing, or require vertical pipe mounting.

  • Have a measuring accuracy of ±2.5% of full scale in the center third of the measuring range, and ±4% in upper and lower thirds.

  • Have a stainless steel sharp-edged orifice.

  • Have a weather-tight external construction.
