The FPD4000 Series represents a positive displacement meter that is affordable and accurate. One primary feature is the ability to maintain consistent accuracy despite changing viscosity conditions. This reliability, coupled with a large turndown range, offers an affordable replacement for older turbine technology. The meter’s solid construction and excellent dynamic response are well suited to the measurement of oil, grease, fuel, solvents, polyurethanes, brake fluid, skydrol as well as other nonabrasive lubricating fluids. Since there is no need for straight run piping upstream or downstream of the flow meter, the FPD4000-Series flow meters are simple to use and to install. The meters produce good resolution and high accuracy at low flow rates. Flow may be bidirectional, such as for cylinder position measurements, without damage to internal parts.
