glass tube rotameter

Our Glass Tube Rotameter is a precision-engineered variable area flow meter designed for accurate, repeatable measurement of low to medium flow rates of gases and liquids. It operates on the float-and-tapered-tube principle, providing direct visual indication of flow rate without the need for external power. Ideal for laboratory setups, pilot plants, test benches, gas distribution panels, and OEM integration, the rotameter offers simplicity, reliability, and long service life. Key Features Clear Borosilicate Glass Tube for high visibility and chemical resistance Direct Reading Scale (LPM, LPH, SCFH, Nm³/hr or as required) High Accuracy: Typically ±2% to ±4% of Full Scale Panel / Line Mounting Options SS 304 / SS 316 / Brass End Fittings Integrated Needle Valve for precise flow regulation (optional) Compact & Maintenance-Free Design No External Power Required Advantages Simple and rugged construction Economical solution for flow measurement Easy installation and replacement Suitable for transparent and clean fluids Quick visual verification of flow status

Rotameters are devices which measure the flow rate of liquid or gas in a closed tube. This product is machined from clear acrylic block and is designed to give maximum accuracy in visibility and ruggedness. The floats are made from stainless steel, PVC and other non corrosive materials. The needle valve is provided for accurate flow control. It is designed to give accuracy of 0.5 to 1% at full scale. The higher accuracy can be made on specific requirement.
