ALVAMT

SMC's ALVAMT series rugged metal tube variable area meters (rotameters) are ideal for high pressure, high temperature and other demanding flow applications where safety is a concern. Features include globally-recognized approvals for use in hazardous environments, integral needle valve for flow control, multiple connection options for easy installation; several material options for corrosion resistance & metering of aggressive fluids and HART or 4-20mA outputs for remote flow monitoring and control. The ALVAMT's excellent repeatability makes it a good choice for batching applications. For versions without electrical output, no power supply is required. The ALVAMT's low-pressure drop provides additional value by allowing for economical pump selection.

FEATURES

 

Excellent low-flow performance.

Versatile design may be used for gas, steam and liquids.
