FLOWTECH Acrylic Body Tube Variable Area Flow Meters (Rotameters) are intended for general in line metering applications (i.e. for Gas & Liquid) where operating conditions are with the limitations of Acrylic Body metering tubes. These are the principle of Variable Area. The float moves freely up and down tapered Acrylic body Tube with fluid flow from bottom to top. The float takes up a position where buoyancy forces and the float weight are balanced in proportion to flow rate. The Vertical position of the float as indicated by scale is the measure of the instantaneous flow rate.
When fluid or gas flows through a taper tube containing a float, a pressure difference of P1 and P2 iscreated between upper and lower side of the float. The float moves upwards by a force obtained bymultiplying the pressure differential by the maximum cross-sectional area of the float. Due to taper tube, as the float moves upwards, the fluid passing area increases as a result of which thedifferential pressure decreases. Upward movement of float stops when the dead load is dynamicallybalanced by the differential pressure. Tapering of metering tube is so designed that the verticalmovement of the float becomes linearly proportional to the rate of flow and the scale is provided toread the position of the float, thus giving birth to flow rate indication
Precociously machined from imported transparent solid acrylic block tapering tube is done by special tools.
- Suitable for water, saline water, air N2 H2 and natural gases.
- Available from 15 NB to 150 NB pipe size and ranges between 30 to 60,000 LPH of water at ambient temperature.
- High & Low Flow switches on request.
- Along the side of the tube, the acrylic body rotameter has a scale or graded marks. Based on the location of the float, these marks are calibrated to produce flow rate data. The user may readily assess the flow rate of the fluid by monitoring the location of the float relative to the scale. Acrylic body rotameters are used in a variety of sectors, including as water treatment, chemical processing, pharmaceuticals, and HVAC (Heating, Ventilation, and Air Conditioning) systems. They are frequently employed in settings requiring visual monitoring of the flow rate as well as compatibility with a wide range of fluids.
FAQ about Acrylic Body RotaMeter:
Can I use an acrylic body rotameter to monitor both liquid and gas flow?
Yes, acrylic body rotameters can measure both liquid and gas flow. To acquire reliable results, however, it is critical to ensure that the rotameter is appropriate for the specific fluid and operating circumstances.
Can I use a rotameter with an acrylic body for high-pressure applications?
Acrylic body rotameters are primarily used in situations requiring low to moderate pressure. It is best to consult the manufacturer for suitable alternatives or consider using a different type of flow meter in high-pressure settings.
Can I use an acrylic body rotameter to change the flow rate?
Some acrylic body rotameters have a flow control valve or a bypass tube that allows the flow rate to be adjusted.
