Metal Tube Variable Area Meter

Product Description

The ALVAMT 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: mechanical readouts for use in locations where power is not available or in hazzardous areas; analog and digital LCD local display options, multiple process connection options; several avaliable materials of construction for metering of aggressive fluids and corrosion resistance; and HART enabled 4-20mA output to provide for remote monitoring and control. The ALVAMT’s excellent repeatability makes it a good choice for batching applications. For versions without electronic output, no power supply is required. The ALVAMT’s low-pressure drop provides additional value by allowing for economical pump selection.
