The INVALCO 2”-3” Abrasive Service Flow Meter is a unique one-piece, patented cartridge design which enables replacement of turbine meter internals with minimal downtime. The meter was designed to operate within pressures from vacuum to 15000 psi. Replacement cartridges are fully calibrated and are ready for installation with no special tools required. By simply removing the union seal and the slide in cartridge retainer, the internals slide out of the body.
