Footnotes:

Because of the compressible nature of gas, meters used in this service may be subject to float bounce:

  • The meter is used in very low pressure applications.
  • There are more than two pipe diameters between the meter and a control valve.
  • The gas being metered is a low specific gravity gas.
  • The meter is operating below 20% of full scale flow.
  • Back pressure is insufficient to stabilize the float.

Tubes with the designation “G” have rib-guided floats. Tubes designated “P” have pole-guided floats
