The Series VA-K Flowmeter Kits offer an economical means of acquiring diverse flow
measurement capability. The kit includes a completely assembled flowmeter (available with
Aluminum or 316 SS end fittings) and three interchangeable 150 mm flow tubes. All flow
tubes are supplied with a glass float installed. Spare 316 SS and Tantalum floats are included
to extend flow capacities. Series VA-K kits also include a high flow valve cartridge, tripod
base, tweezers, pushrod and locking tool for changing floats and flow tubes, correlation
charts and plastic carrying case.
