Pneumatic Flow Meters

Pneumatic Flow Rate MetersFor 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.
  • Be Lake Monitors No. G _ _ – _ _ _ – _ _
