Badger Meter High Temperature Fluid Meter - Manual (Page 5)

INTRODUCTION
The Inline Liquid Flow Meter is a rugged industrial class inline flow rate indicator, offered in aluminum, brass or stainless
steel models to monitor a wide variety of liquids . Available in seven port sizes from 1/4" to 3" for flow ranges from 0 .02…0 .20
(0 .1…0 .75) through 20…300 gpm (100…1100 lpm), the meters are calibrated at 0 .876 specific gravity for oil or other
petroleum-based fluids, 1 .0 for water or other water-based fluids, or 1 .18 for phosphate ester liquids .
The flow meter is equipped with a 360° rotatable guard/scale which allows the meter to be installed in any orientation
without regard to scale direction . Once the meter is permanently installed, the guard/scale can be rotated 360° to
optimize readability .
In addition, the unique spring-loaded design of this variable area flow meter decreases viscosity sensitivity and allows it
to be installed in any position, including inverted, without affecting accuracy . An optional inverted scale is available for
these applications .
The standard flow meter is a unidirectional device . If required, a reverse flow bypass option is available for the oil, phosphate
ester and water-based fluid models . Note that flow is measured in the forward direction only .
• Aluminum models are offered as a rugged, low cost flow meter for monitoring noncorrosive water-based or
petroleum-based fluids under operating pressures up to 3500 psi (241 bar) .
• Brass meters are recommended for water monitoring applications or other systems where corrosion inhibitors
are not present .
• Stainless Steel is available for monitoring hydraulic systems operating at pressures up to 6000 psi (414
bar) or other corrosive caustic fluids, such as acetic acid . For further construction material information, see
"Fluid selection chart" on page 16 .
