VARIABLE-AREA DIAL FLOW
INDICATOR


The Bailey-Fischer & Porter 10Aa227A Dial Flow
indicator is an inexpensive, all metal, variable area
meter for high pressure, high temperature flow indi-
cation. The metering float is magnetically coupled
to an indicator housed in a fully gasketed, reinforced
fiberglass case which is particulary suited for
corrosive atmospheres and outside installations.
This series is also available with SOFtlOOO Vertarator
5O~ type Pneumatic or Electronic Transmitter or
Electronic Alarm. Refer to Specification 1 0fl227-OV.

Design Features
  • Easily Installed: Unit mounts directly in vertical pipe line. Indicator case can be positioned 3600 around meter body for best viewing angle.
  • Less Down Time: Through-flow design prevents float-restricting buildup of dirt or process fluid.  Snap-in retainer ring permits easy disassembly for cleaning.
  • No Seals to Leak: Due to one-piece construction of seamless stainless steel tubing.

Sizing
For sizing flowmeters with type 316 stainless steel floats when the required flow is of liquid (density 1.0 g/cc), or of gas (sp gr of air and at 14.7 psia and 70 F or 101.3 kFa abs and 21 C) the capacity table may be entered directly.
