Panel mount rotameter is a compact, precision instrument used for measuring and monitoring the flow rate of liquids or gases in low to medium flow applications. Designed for integration into control panels or enclosures, it provides clear, front-facing flow visibility and optional flow control.
Panel mount rotameters operate on the variable area principle, where a float rises and falls within a tapered, transparent tube as the flow rate changes. The float’s vertical position corresponds to a calibrated flow rate scale printed directly on or alongside the tube.
Panel-mount design with front visibility and mounting brackets or rear-threaded fittings
Transparent tapered flow tube (acrylic, polycarbonate, or glass) for easy reading
Precision float (stainless steel, glass, or polymer) provides stable indication
Direct-reading scale in LPM, GPM, etc.
Optional needle valve for flow regulation (inlet or outlet)
