(As seen at Chem Show '97) These positive displacement flowmeters, marketed as the Hoffer Oval Gear or H.O.G. series, provide
solutions for customers with both low and high viscosity fluids. Prior to this, Hoffer needed to recommend
other manufacturers for flow applications beyond 200 centistokes.
Designed for industrial use, the series is constructed of 316 stainless steel with other materials of
construction optional. Available with a variety of end connections including the standard FNPT, the
flowmeter has a high temperature range of 850 degrees F, is pressure rated up to 3000 psi , and has
been independently tested at +/-.25% or better on viscous applications.
The smooth gear design offers advantages such as higher flowrates on high viscosity liquids, a
significantly higher K-factor than other gear type flowmeters, and better flowmeter resolution particularly
at the lower flow rates. A comprehensive line of signal conditioners and converters, along with indicators,
totalizers and flow computers are offered to augment the H.O.G. series.
