- VISION 2000 Flowsensor
The hall effect turbine flow rate sensor is ideal for OEM applications
involving low flow liquid monitoring. The low cost coupled with
1/ 2% repeatability makes it an ideal candidate for replacing
dispensing timer systems. Unlike existing timing systems, turbine
technology is not influenced by changes in system pressure caused
by aging filters. The sensor s standard power and output specifications
make it easy to retrofit to existing controllers.

The liquid turbine meters of
the series VISION 2000 are for the exact measuring of small
quantities of liquids. The actual flow as well as the already
passed flow can be measured.
Principle:
Flow causes the bladed rotor
of the VISION 2000 to turn at an angular velocity directly
proportional to the veclocity of the fluid measured. As the blades
pass beneath a magnetic pickup coli,a frequency signal is generated.
Each pulse is equivalent to a discrete volume of fluid. The frequencypulse
is directly proportional to the rotor angular velocity and the
flow rate.The waves are readily transmitted to local or remote
electronical instrumentation.
Advantages:
The large number of pulses gives
a good resolution. As the mass of the turbine are very small
theresponse time is very short. It is not necessary to install
a straight length of pipeline at the upstreamside.
The simple mechanical construction of the sensor VISION 2000
guarantees a long lifespan
without any loss of accuracy.Pressure pulses do not affect the
measuring system. |

OPERATING AND INSTALLATION INSTRUCTIONS: |
|
|
|
|
1. Check compatibility of media
with sensor material Grilamid TR55 (PA 12) Grilamed_prospekt_4007_e.pdf
2. Solid ingredienst in medium require a filter in front of sensor
to avoid soilings
3. Install sensor into properly cleaned pipeline only
4. Check electrical connection according to electrical wiring
plan
5. Do NOT exceed specificated limits
6. The VISION 2000 is a volumetric measuring device, i.e. air/gas
in liquid will be included
in mesured volume
7. Correctly installed the sensor works entirely maintenance
free
8. The VISION 2000 is an industrial product and not for general
public use and is to be installed and applied by trained personnel
only
We recommend to test the sensor
for the intended purpose and to ascertain - independent of
specificiations - feasibility of application.
- 11. Initial Set-up
-
- Please make sure, that the installation
is filled slowely with media PRIOR switching on!
- Not filling up the system before
turning on system can result in damage of bearings, since an
multiple overload might appear.
