DESCRIPTION

The INVALCO General Purpose 1% 3/4”-2” Cartridge Style Turbine Meter is a unique one piece cartridge design which enables replacement of turbine meter internals with minimal downtime. A single upstream retaining ring is removed and the internals slide out. Replacement cartridges are fully-calibrated on water and are ready for installation with no special tools required.

INVALCOʼs proven double sleeve bearing and flow through design provide excellent performance and unequalled service life in non-lubricating and solids contaminated fluids.
