Design Features
- HIGH STRENGTH STAINLESS STEEL BODY: The body is
corrosion resistant stainless steel rigidly constructed to maintain tube alignment
and resist pipe strain.
- "SNAP-IN" TUBE CONSTRUCTION: Minimizes the downtime
needed to clean the meter tube or to change the meter range.
- POLYCARBONATE OPERATOR PROTECTION SHIELD: Safety
tested shield will protect personnel from glass fragments in the rare event of accidental
tube breakage.
- COMPONENT FLEXIBILITY: All parts for the four scale lengths
except bodies, tubes, and protector shields are interchangeable providing simplified
maintenance and a reduced spare parts stocking requirement.
- OPTIMUM VARIETY: The Bailey-Fischer & Porter PURGEMASTER
is available in 1-1/2, 3, 5, and 10 inch scale lengths and end fitting materials of brass,
KYNAR® and stainless steel.
- INTERNAL BACKCHECK: Restricts back flow and draining of
process fluid when metering tube is removed. (Not available with outlet control valve.)
- CONTROL VALVE: The optional control valve provides a smooth
fine degree of adjustment.
- VERSATILE FLOW CONTROLLER: The optional 53R-2110 Differential
Pressure Regulator is designed to give reliable flow control regardless of changes in
upstream pressure.
- ADJUSTABLE ALARMS: Single (mm. or max.) or Dual (mm. &
max) alarm sensors are adjustable over the entire meter range.
- CHOICE OF OPERATING POSITION: The meter can be inverted and
its tube reversed to change the control valve position from the inlet to the outlet.
Internal backcheck is to be removed when control valve is positioned in the meter
outlet.

NOTE 1: When combined with a 53R2110 differential Pressure Regulator, the PURGEMASTER
can control a flow of liquid or gas that is subject to varying line pressure. However, due
to gas compressibility, the true value of mass flow rate of a gas can be measured only if
the downstream pressure remains constant.

Alarms
Principle of operation
The ring sensors with a bistable switching action picks up the relay in the amplifier when
the ball float reaches the trigger level and remains in that position, even if the
float continues to move towards the alarm zone, thus leaving the trigger level. The relay
will drop out as soon as the float crosses the trigger level from the opposite
direction, and moves back from the alarm zone into the normal operating range. The actual
float position - above or below the trigger level - is precisely indicated.
Explosion hazardous operation is feasible, since the ring sensor used is an intrinsically
safe switch with intrinsically safe circuit. Due to the relatively short metering tube,
type 10A6131/41 is suitable either as a minimum or a maximum alarm. Model 10A6132/42 is
recommended if both alarm operations are designed.
Design Features
- Sensor height 14 mm, therefore only small coverage of the
scale.
- Integrated clamp device directly to the meter body. No
automatically adjustability during operation possible.

| Caution
|
Glass tubes are not recommended for either hot or
strong alkalies; fluorine. or hydrofluoric acid. Meter tubes should be periodically inspected for signs of
near. Erosion, stress cracks or nicks provide early
naming for tube replacement. With certain fluids, the glass may erode unevenly so that wear is not visibly
noticeable. If wear is suspected, the tube should be replaced.
