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.
VISION 2000®系列的液体涡轮流量计用于精确测量少量液体。可以测量实际流量和已经通过的流量。

 

Principle 原理

Flow causes the bladed rotor of the VISION 2000 ® to turn at an angular velocity directly proportional to the velocity of the fluid measured. As the blades pass beneath a magnetic pickup coil, a frequency signal is generated. Each pulse is equivalent to a discrete volume of fluid. The frequency pulse is directly proportional to the rotor angular velocity and the flow rate. The waves are readily transmitted to local or remote electrical instrumentation.

Advantages 优点

The large number of pulses gives a good resolution. As the mass of the turbine are very small the response time is very short. It is not necessary to install a straight length of pipeline at the upstream side. 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)
2. Filtration is mandatory if solid particles or fibres are present
3. Install sensor into properly cleaned pipeline
4. Check electrical connection according to the electrical wiring plan
5. Do not exceed the specification limits
6. The VISION 2000 ® is a volumetric measuring device, i.e. air/gas in liquid will be included in measured volume
7. Correctly installed the sensor works entirely maintenance free
8. The VISION 2000 ® is not for general public use and is to be installed and applied by trained personnel only

Disclaimer

We recommend to test the sensor for the intended purpose and to ascertain - independent of specifications - feasibility of application.
