VEKSLER (ABR-191)
High Volume Acrylic Body Rotameters are useful for general
purpose application like water, air and inert gases.
The tapered metering tube is drilled in the solid block
and the scale is engraved on the body itself.
The other features are similar to the of the GTR-19 except
that it cannot be used for corrosive application and for
temperature above 60 Deg C.
Flow range is available from 100 to 40,000 LPH for water
and 0.5 to 450 m3/hr for air |

GLASS TUBE ROTAMETERS |
|
| |
Glass Tube Rotameters
consist of a tapered glass tube mounted vertically
in a frame with the small diameter at the bottom
and large end up. The tube contains a free moving
float that rests on the stopper at the base of the
tube. When the liquid flows, the float rises until
its weight is balanced by the up thrust of the fluid
and the float reaches a position of equilibrium.
At this position it indicates the instantaneous
rate of flow.
The flow rate can be read from the adjacent scale.The
pressure drop across the float is equal to its weight
divided by its maximum cross-sectional area in the
horizontal plane. Both in orifice type meter and
in the Rotameter, the pressure drop arises arises
from the conversion of pressure energy to kinetic
energy and from the frictional losses. Thus Rotameter
may be considered as an orifice meter with a variable
aperture and the formula derived for the orifice
meter is applicable here with only minor changes |

METAL TUBE ROTAMETERS |
|
| |
| Metal Tube Rotameters
are available for use in harsher duties in liquids
and gases where glass tubes are not allowed for
safety reasons. These are very rugged and robust
yet inexpensive for flow rate indication purposes.
MTR can be used for opaque and turbid fluids at
high operating temperature and pressures.The Flow
is indicated by a pointer, which is magnetically
coupled with the float that rises in a tapered tube
with increase in flow. |

- SS/ Teflon lined body
- Die-cast Aluminum housing with Aluminium
pointer and SS 304 hardware
- High Pressure and Temperature service
- Linear flow reading and output signals

BYE PASS ROTAMETERS |
|
| |
|
|
| |
VEKSLER Bye Pass Rotameters
are available for line sizes 2" and above. The complete
assembly consists of an Orifice plate, Flanges of the
main pipe line, by-pass piping with isolation valve and
fittings, range orifice and the Rotameter. The Orifice
calculations and design is bases on IS or BS standard.
By-Pass Rotameters are the most economical solution for
flow measurement in large pipe lines and for large rate
of flow but the use is limited to solid particles and
slurries that tend to clog the range orifice and may result
in malfunctioning. |

|
DESIGN FEATURES |
| |
- SS304/ SS316 Orifice plate
- CS/Forged and SS Flanges
- Accuracy +/-2% of full flow
- Also available without main line flanges
- Optional alarms and 4-20 mA output
