MEGARF 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, output and digital LCD local display options, multiple process connection options, several available materials of construction for metering of aggressive fluids and corrosion resistance, HART enabled 4-20mA output to provide for remote monitoring and control. The MEGARF’s excellent repeatability makes it a good choice for batching applications. For versions without electronic output, no power supply is required. The MEGARF's low-pressure drop provides additional value by allowing for economical pump selection.
