The PW VF-100 offers the same reliability, proven performance, and value of our multiphase SONARtrac flow meters. As a result of its non-contact design, the PW VF-100 installs on existing process lines and allows on-line volumetric flow measurement on virtually any type of pipe material and lined pipe, without any coupling gels or special adjustments.
