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.
