 MTW / G4 Diaphragm Gas Meter 211CFHMTW / G4 Diaphragm Gas Meter 211CFH

FEATURES

  • Pulse Output (1 / cu ft)
  • Sealed Register for Tamper-resistance
  • Compact Design
  • Low Noise
  • Stamped Steel Case
  • Sprague #1A Connections, not tapered NPT

SPECIFICATIONS

  • Flows from 1.4 ft
  • Working Temperature Range: 4° F to 122° F
  • Pulse Output 12VDC max @ 10mA
  • 7.5 psi max Operating Pressure
  • 0.04 cu ft Cyclic Volume

APPLICATION

For use in submetering applications where compact size and pulse output are desired. The MTW / G4 gas meter is designed for environments where temperature compensation is not required. The meter incorporates Sprague #1A top connections to allow industry-standard swivels to be installed thus negating the need for plumbers to “field design” a union system. This straight mechanical thread configuration is standard for all municipal meters as it allows the swivels to seal on a flat washer rather than relying on pipe dope and tapered NPT threads.
