Volume sensors VS Series

The positive displacement flow meters of the VS series measure the volume flow of liquids according to the meshing gear principle. Two matched gear wheels are precisely fitted in the housing. The rotation of the measuring unit is detected tooth-by-tooth by a non-contact signal pick-up system and is converted into digital pulses. The precision gear flow meters of the VS series offer unrivaled performance, linearity and resolution for most accurate measurement of clean viscose liquids. They are available in cast iron and stainless steel versions to suit your application.

VSI Series - High definition with special preamplifier

As a very high resolution is necessary for precise and exact flow measurements, the volume measurement Vm must be resolved even more than with conventional preamplifiers. VSE has therefore developed the preamplifier with interpolation, with which a selectable resolution of up to 64 flanks (16 pulses) per period can be attained.

This individually programmed high resolution enables to set the volume measurement Vm optimally for each provided case of application. Furthermore, new applications can be availed with the higher resolution. With the VSI flow meter, measuring, controlling and regulating in lower flow ranges, in zero flow, in both flow directions as well as dosing and filling of small volumes becomes possible.

Advantages

  • Accurate volume measurement
  • Fast detection of flow changes
  • Higher accuracy, faster response times
  • Higher frequency with low flow rates
  • Measuring media with high viscosity
  • Precise measurement and dosage of volume
  • Better and more precise operations of digital controls
  • Faster and better analogue output
