Wallace &
Tiernan Metal Tube Rotameter
Available in a
variety of tube sizes (1/2, 3/4, 1, 1-1/2 and 2 inches) and flange facings
and ratings, these metal-tube rotameters give reliable flow measurement
over a 10:1 range for aggressive fluids at high temperatures and
pressures. (See Data Sheet for pressure and temperature limits.) Metering
accuracy is 2% of full scale (1% with custom calibration).
Available options include a 4-20 mA output flow signal and high/low alarm
switch. Flanges available have ANSI 150-, 300-, and 600- lb. ratings.
Flanges are raised, flat, large female, tongue-and groove, or ring-joint
face. The standard tube-and-float material is 316 stainless steel. A
Hastelloy C float is also available. The magnetic indicator has a 6-inch
scale. Percent of maximum flow is the standard calibration; gpm water,
scfm air, or special graduations are optional.
NON-FOULING FLOAT
The extra-long float magnet has reduced flux density and is located above
the metering disk. This discourages accumulation of magnetic particles,
especially on the disk edge where they can cause errors in indication and
calibration drift.
NO
FLOAT EXTENSIONS
When the float is at rest, nothing projects beyond the flanges. Spool
pieces are not required for installation, eliminating a frequent cause of
damage when removing meters from a line.
GAS
MEASUREMENT TO 0 PSIG
A unique dry snubber is standard on this Varea-Meter used for gas service.
It stabilizes the float, gives reliable indication down to atmospheric
pressure. It eliminates dashpots, offset piping, and horizontal
connections.
RELIABLE MAGNETIC COUPLING
Almost frictionless rotation of the instrument magnet and its powerful
bond with the float magnet give a dependable magnetic coupling. A metal
shield shunts stray magnetic fields around the coupling.
TRANSMITTER AVAILABLE
A 4-20 mA transmitter is available to provide remote indication of flow
rate.
FLOW
SWITCH AVAILABLE
This optional, magnetically coupled switch gives reliable high and/or low
flow switching. It is easily set to open or close on increasing or
decreasing flow. It is compact and easily mounted on the meter. Available
in a general purpose or a UL listed hazardous location arrangement.
