The AW Gear Meters SRZ Helical Gear Flow Meters is constructed of two highly accurate cycloid shaped screw spindles that mesh and rotate inside the cylindrical housing with two overlapping holes in the form of a figure 8, which forms the measuring chamber. The medium flows in an axial direction rotating the spindles without pulsation.

The SRZ helical gear flow meter is highly accurate with wider measuring ranges, and is largely independent of your fluid viscosity. The lower pressure drop compared with other flow metering types makes this meter perfect for measuring polyurethanes and polymer, glues and sealing materials and heavy fuel oils. Flow range 0.1 to 105 GPM, accuracy ±0.5%, repeatability ±0.1%, turndown >100:1, pressure up to 6000 PSI. Available in three flow ranges, constructed of 303/316 stainless steel.
