INTRODUCTION
This volume flow meter is a robust industrial-grade inline gear flow meter that is available in an
aluminium, brass or stainless steel design for the purpose of monitoring many different fluids.
Available in seven connection sizes from 1/4... 3 inches for flow ranges from (0.02...0.20 gal/min)
0.1...0.75 l/min to (20...300 gal/min) 100...1100 l/min. The devices are calibrated to a specific
weight of 0.876 for oil or other oil-based fluids, 1.0 for water or other water-based fluids or 1.18
for phosphate ester fluids.
The volume flow meter is equipped with a 360° rotatable protective case/scale that allows it to
be installed in any position without needing to consider the scale direction. As soon as the
volume flow meter is permanently installed, the protective case/scale can be rotated 360° to
make it easier to read.
In addition, the unique spring-loaded design of this volume flow meter reduces its sensitivity to
viscosity and allows it to be installed in any position, including inverted, without losing any
precision. An optional inverted scale is available for such applications.
The standard volume flow meter only works in one direction. If required, a bypass option with
inverted flow is available for the mineral oil, phosphate ester and water-based fluids models.
Please note that the volume flow is only measured in the direction of the arrow.
Aluminium models are offered as robust, low-cost volume flow meters for
monitoring non-corrosive, water-based or oil-based fluids. Oil-based fluids for
operating pressures of up to 250 bar (3500 psi).
Brass models are recommended for water monitoring applications or other systems
where there are no corrosion inhibitors.
Stainless steel models are used for monitoring hydraulic systems with operating
pressures of up to 350 bar (6000 psi) or other corrosive, caustic fluids such as acetic
acid. You can obtain further information from your technical consultant.
