PRODUCT OVERVIEW
The panel-mounted acrylic tube rotameter is the simplest and most economical
rotameter for non-corrosive gas and liquid flows with panel mounting
capability. Sangan Sanat panel-mounted acrylic tube rotameters are generally
manufactured in small size and low flow rates. The operation of a rot meter is
based on the variable area principle. Variable area refers to the area between
a tapered acrylic tube and a float inside the tube. The flow of a fluid raises
the float inside a tapered tube, increasing the area through which the fluid
can pass. The larger the flow, the higher will be the float position.
Float position is directly proportional to the flowrate of the fluid, and it
moves up or down in proportion to the fluid flowrate. Therefore, the scale may
be graduated directly with the unit of flow. Optional inlet (or outlet) valve
makes it possible to control flow rate manually.

SELECTION GUIDE FOR WATER/AIR
Common ranges of available flowmeters for water flow measurement are shown in the table below. If you need a different range or fluid than shown, please contact us.
- Fluid name (water or air):
- Flow range (minimum and maximum):
- Operating pressure:
- Operating temperature:
- Maximum pressure:
- Maximum temperature:
SELECTION GUIDE FOR OTHER FLUIDS
The flow ranges specified in flow ranges table are for air and water, only. If the fluid is other than air and water, specify the below information. Our sales engineers will help you choose the right rotameter.
- Fluid name:
- Flow range (minimum and maximum):
- Operating pressure:
- Operating temperature:
- Maximum pressure:
- Maximum temperature:
- Fluid density:
- Fluid viscosity (only for liquids)
NOTES
- Each meter is calibrated individually in our flow calibration site. As a standard rule, meters intended for liquid measurement are calibrated by water and those intended for gas measurement are calibrated by air. We also provide correction factors to convert meter reading to operating condition.
- Rangeability of rotameters is generally 10:1. This means that if the desired maximum flow rate is 10m3 /h, the minimum measurable flow rate is 1m3 /h. The meter cannot measure from zero!
- The scale on the meter is correct ONLY for the specified fluid at pressure and temperature shown on the meter. If the fluid, operating temperature or operating pressure are different from what is written on the meter scale, correction factors need to be applied. In this case, contact us to provide you with the necessary correction coefficients.
