VS positive displacement flow meters are volume rate measuring sensors based on the meshing gear principle and are designed for use with liquids. Two precisely matched gear wheels are enclosed in a very accurately machined housing. Gear rotation is sensed by a noncontacting signal pick-up System. Each work produces one signal.
Performance data
Flow range 0,002 up to 525 l/min
Pressure range up to 450 bar
Temperature range -40 up to +210°CFrequency range up to 2000 Hz
Viscosity range 1 up to 100.000 cSt
Applications
Measurement and dosing technology
Hydraulic systems
Monitoring technology systems
Open/closed loop control
Process control
Automobile industry
Plastics technology
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
