Dwyer Series VA-K Variable Area Flow Meter Kit

 Flow includes Flow Transmitters, Flow Sensors, Flow meters, Sight Flow Indicators and Water Meters. Mass Flow meters, Controllers, Flow Indicators and Controllers are ideal for measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston.

Flow meters indicate flow rate. The different sensors include dial, in-line, ultrasonic, orifice plate, totalizing meters, variable area, venturi, or with switch output. The different designs of the flow meters have a variety of applications.

Dwyer Series VA-K Variable Area Flow Meter Kit | Descriptions

Tapered bore in-line indicators for flow rate. Ideal for high purity or corrosive liquid applications, gas and liquid applications, air samplers and medical applications. Flow meters are shipped assembled and ready for panel mounting.

The Series VA-K Variable Area Flow Meter Kit offer an economical means of acquiring diverse flow measurement capability. The kit includes a completely assembled flow meter (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.
