About    Founded in 1972, AALBORG®is well-known throughout the world as a primary manufacturer of the Company precision instrumentation for flow measurement and control. We operate two divisions: The Variable Area Division manufactures a complete line of glass tube rotameters. These flow meters are available with aluminum, brass, stainless steel or PTFE wetted components. AALBORG® also manufactures a unique line of PFA tube meters for ultrapure or corrosive applications. Precision barstock stainless steel or brass needle valves, as well as PTFE valves, are also manufactured in this division. The...

PRINCIPLE OF OPERATION When compared with other types of flow instrumentation, variable area interchangeable flow meters offer the most practical, precise and economical means of visually indicating flow rate measurement. They require no electrical connections, and have low meter related pressure drops. Meters are available in a large selection of flow rates and configurations, to accommodate the unique requirements of most applications. Included in the line are flow tube assemblies, single and multiple tube flow meters. PTFE-Glass meters are for metering corrosive fluids or for high purity requirements....

INTERCHANGEABILITY Flow tubes and other components are thoroughly interchangeable resulting in greatly increased versatility. Meters are even interchangeable with standard sizes made by other manufacturers. As a result of simple assembly and installation procedures, it is possible to use several sets of flow tubes in conjunction with one mounting frame. flow tubes ✓ Precision fabricated from heavy walled, shock resistant borosilicate glass. ✓ Bores are uniformly tapered or formed with internal "rib-guides" or flutes. ✓ Floats are retained by TFE plugs. ✓ OPTIGRAD™ scales minimize parallax and...

STANDARD VALVES (CVTM) BUILT-IN VALVES Meters are available with built-in needle valves (CVTM), high precision metering valves (MFVTM) with “non-rising stems”, or with no valves. Built-in valves are mounted at the inlet (bottom) or outlet (top) of flow meters. Generally, for gas metering it is recommended that valves are positioned at inlets - for liquids valves may be positioned either at inlets or outlets. For vacuum service, valves must be mounted at outlets. If unspecified at the time of ordering, meters will be shipped with valves mounted at the inlets. The VALVE NEEDLE turns as it travels...
