Metal Tube Rotameters – Precise Flow Measurement under Critical Conditions
Metal Tube Rotameters are essentially variable area flowmeters. They maintain a constant differential pressure across the annulus area, with flow rate measured in relation to the float’s position within this area. A magnet senses the float’s position and indicates it on the dial as the flow rate. These rotameters conform to industry standards.
Advantages of Metal Tube Rotameters:
- Simplified piping and reduced space requirements.
- Permanent magnetic linkage between metering float and motion position transmitter.
- Precision swaged metering tube.
- Heavy-duty welded float and guide construction.
- Easily removable guide cartridges for cleaning.
- Available with electrical transmitter, flow indicator, or alarm.
Applications of Metal Tube Rotameters:
- Scientific laboratories
- Research centers

Metal Tube Digital Rotameter – Precise Digital Flow Measurement under Critical Conditions
FLOWTECH’s Digital Metal Tube Rotameter is designed for applications where a current output with totalization is required. It’s a rugged, versatile, and accurate variable area (VA) flow meter with a 2.0% full-scale accuracy. The inner float’s magnetic field is detected by a highly sensitive magnetic field sensor, providing a digital readout. Operating on battery power, this flow meter doesn’t require an electrical connection. It comes with an inbuilt two-wire transmitter providing 24 V DC and a 4-20 mA output signal.
Design Features of Metal Tube Rotameters:
- Simplified piping and reduced space requirements.
- Permanent magnetic link between metering float and motion position transmitter.
- Precision swaged metering tube.
- Removable guide cartridges for cleaning.
- Available heights: 250, 300, 350, 450, 500 mm.
- Available flange sizes: 15 NB to 150 NB & flow rates from 200 LPH to 1,00,000 LPH.
The Metal tube digital rotameter has a tapered tube, usually made from glass with a ‘float.’
It is challenging to handle the glass tube type. It must be fixed vertically, and it’s not suitable for pulsating services.
The main source of error in a rotameter is the variation of density in the fluid.
- Extensive range of applications in chemical, oil and gas, pharmaceutical, and water treatment sectors.
- High accuracy for flow measurement and precise control.
- Corrosion resistance due to metal tube construction, suitable for use with corrosive fluids.
- Provides real-time flow rate readings for analysis and process monitoring.
- Low pressure drops, reducing energy losses in the system.
