Flow meter SF800
The patented SF800 technology is the basis for the highgrade fluid flow meters. It makes a constant reliable high-accuracy flow measurement throughout a large flow rate (0,5-20 l/min) possible.
One of the biggest advantages of the SF800 sensors is that because of the resistance-free working-principle (the rotor floats in the medium) the SF-800 fluid flow meters are not subjected to wear. To prevent any leaking, the SF-800 is sealed by ultrasonic sound waves.
On request, an additional protection for the electronics in the form of an added silicone-layer is possible. Because solid particles and/or contaminated medium can damage the sensor or influence the measurements, we advise the use of a filter (20 micron); if necessary these filters can be provided as well.
Working Principle The patented SF800 technology is the basis for these high-graded flow meters. The geometry of the rotor housing (causing a radial flow in) in combination with the light weight Vectra rotor (0,04 grams) makes the rotor float in the medium. Because the rotor floats there is the measurement process is nearly resistance-free, guaranteeing high accuracy, durability and linearity.
An integrated PCB emits an infrared signal, which is interrupted by the three blades of the rotor. SMD components transform the interrupted signal into a pulse. Because of the construction of the rotor housing, the SF800 flow sensors are practically insensible to high pressure.
The materials used (PVDF and Vectra) are to a great extent chemical-resistant and temperaturedurable. Contrary to many other fluid flow measurement systems, the SF800 sensors do not have to be calibrated. The limited number of parts and intelligent design results in product with infinite application possibilities and an excellent priceperformance ratio.
Instructions for installation and use Before putting the flow-meter into operation, please note the following:
1. 2. 3. 4. 5. 6. 7.
8. 9.
10. 11.
Hose discharges may not be subjected to pressure when the flow meter is put into operation. Medium-supply lines must be thoroughly cleaned before use. Use of a 20 (Micron) pre-filter is recommended. Solid particles or contamination in the medium may damage the flow meter and/or influence the measurement results. IMPORTANT: WATCH ARROW ON FLOW METER TO INSTALL IT IN CORRECT FLOW DIRECTION. Once the flow meter has been installed, the system should be filled slowly, to avoid air damaging the rotor. Hook up electronic connector to the flow meter. Make sure that the electrical connections have been hooked up as indicated on this diagram. Make sure electronic connector is not coming into contact with liquids. This may influence measuring results negatively. Remember to remain within the minimum and maximum flow-rate limits as indicated. Avoid any UNCONTROLLED AIR PRESSURE through the flow meter. High bars at the beginning will results in more than 38.000 rotations per second of the rotor, will DESTROY rotor blades. The measurement principle is based on volume measurement; air in water, for example, is counted as a medium. Once the flow meter has been installed in accordance with these directions, a smooth operation is guaranteed.
