Data sheet
DESCRIPTION
The small turbine meter VISION measurement technology is
ideal for the accurate measurement of low viscous and non-
aggressive fluids. The VISION 1000 series is most suited for
the measurement of flow rates from 0,1 to 2,5 l/min. The
turbine meters can be mounted in any position.
MEASURING PRINCIPLE
Turbine meters are indirect volumetric meters. When the
fluid passes through, a rotor is activated and the movement
is either electronically or mechanically transmitted outside.
The rotor is turned by the fluid force, proportional to the flow
rate. A Hall effect sensor detects the passage of the rotor and
supplies pulses, which can be utilized for digital or analogue
signal processing. The generated pulses are specified as the
K-factor. The large number of pulses provides high
resolution. As the mass of the turbine is very small the
response time is very short. It is not necessary to install a
straight length of pipeline at the upstream side of the meter.
