Wallace &
Tiernan ARMORED PURGE METER
This armored
purge meter operates over a 10:1 range. Scales are 1 1/4 inches long. The
1/2-inch meter has a gph or scfh scale; the 3/4-inch meter, a gpm or scfm
scale. Each has a percent scale also. Construction with such materials as
nickel-plated carbon or 316 stainless steel with Buna-N, TFE, and 321
stainless trim give maximum corrosion resistance.
HIGH
TEMPERATURE AND PRESSURE OPERATION
Heavy-duty
stainless steel construction assures proper operation to 1500 psi and
800°F. At no time is the glass scale tube exposed to the process fluid. A
stainless steel sheath encloses the glass scale tube, which is sealed by
O-rings.
EASY
MAINTENANCE
An O-ring at the top of the metering plug acts as an
anti-backflow device, eliminating the need for check valves. A bottom port
makes cleaning easy.
FLOW
SWITCH AVAILABLE
This optional
magnetically coupled flow switch gives reliable high and/or low switching.
It is easily set to open or close on increasing or decreasing flow.
Available in a general or a UL listed hazardous-location arrangement.
