VF SERIES VORTEX FLOW METERS PFA or PPS Inline Vortex Flow Meters with Integrated Electronics

The VF-8100 and VF-8200 Vortex Flow Meters are comprised of an inline flow sensor and electronics combined into one unit. Using ultrasonic sensing technology to measure flow rate, Malema Vortex Flow Meters are available in multiple sizes and feature no mechanical seals or moving parts.

The VF-8100 features PFA-wetted materials, which are ideal in the semiconductor industry for applications requiring corrosion-resistant wetted parts, high purity, and a minimal footprint. With PPS-wetted materials, the VF-8200 is appropriate for industrial settings that do not require high-purity flow meter solutions. Both models of the Vortex Flow Meters come in 3/8” 1/2”, 3/4” and 1” sizes and have a flow range of up to 100 l/min for the VF-8100 and 150 l/min for the VF-8200.

Features

  • Straight tube sensor design with a compact footprint
  • PFA wetted materials for the VF-8100
  • PPS wetted materials for the VF-8200
  • No moving parts for reliability and durability
  • Simple construction ensures low-pressure loss and low liquid leak
  • Vortex detector does not contact the fluid
  • Available in sizes of in ⅜” ½”, ¾” and 1”
  • Flow range of up to 100 l/min for the VF-8100 and 150 l/min for the VF-8200
