Dwyer VFC and VFCII Series Visi-Float® Acrylic Flow Meter

Wiratama Mitra Abadi 01 00.01 flow measurement,

Dwyer VFC and VFCII Series Visi-Float® Acrylic Flow Meter is a direct reading, precision machined, clear acrylic body flow meter suitable for both gas and liquid applications. This Series consists of two 5" (127 mm) scale flow meters, the VFC and VFC II. The VFC features PVC 1" female NPT connections and the VFC II units are equipped with acetal thermoplastic 1" male NPT fittings.

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.
