The INVALCO 2"-3" Abrasive Service Flow Meter is a high-pressure turbine meter built for abrasive fluids, with an abrasion-resistant rotor and supports and carbide sleeve and ball bearings. It uses the same patented one-piece, field-replaceable calibrated cartridge as the INVALCO high-pressure TFM: remove the union seal and slide-in cartridge retainer and the internals slide out, no special tools. 4340 body (100 ksi minimum yield, impact tested at -20 °F) with WECO 1502 union nut, segments and seals standard; rated from vacuum to 15,000 psi.

Spare calibrated cartridge if field exchange is planned
The bulletin has no model code. Bulletin error to confirm with the factory: the K-factor P/L column does not match the P/GAL values (2" printed 246 p/L for 65 p/gal, about 17 p/L expected; 3" printed 77 p/L for 20.5 p/gal, about 5.4 p/L expected). The P/BBL values are consistent with P/GAL.
