* Tubes designated “G” have rib-guided floats. Tubes designated “P” have pole-guided floats.
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.
