NOTE: Do not use the MB, TB or CB bearings on dirty fluids or those with particulate entrained. Graphitar (GS) and Teflon (TS) sleeve bearings are now discontinued. Consult Tryon Trading if you have a special situation regarding these discontinued items. Liquid flow meters may be purged with gas, including low pressure steam, as long as the flow rate through the meter does not exceed the maximum flow listed in the Sponsler Meter brochure 5007. This is a guide only. Final applications must be approved by the factory.
