Profile: Crane flowmatic maintains complete capabilities for the design and manufacture of the flow measurement equipment. We offer complete in-house tool design capabilities as well as CNC plasma cutting equipment. A wide range of orifice fittings are available in inventory, ready for immediate shipment. The carrier mechanism and orifice fitting have O rings which compress to allow a metal to metal fit between the machined surfaces. Precision machining of the carrier opening ensures perfect plate and bore alignment once the assembly is installed in the fitting.
