SF800 - Low Pressure Flow Meter The patented SF800 is an all purpose flow meter with an excellent price-performance ratio. It is suitable for a wide range of applications and large variety of fluids, and covers flow velocities of 0.5 to 20 liter per minute at temperatures of -20 to +90'C and an operating pressure of 16 bar (max 40 bar). The SF800 is entirely made of high-quality plastics and composites with great chemical and thermal resilience. The housing is made of PVDF, a high grade PVC, while the internal rotor of only 0.04 gram is made of Vectra, a liquid crystal polymer of very low weight. Both material are not susceptible to limescale. An integrated PCB emits the infrared signal, which is interrupted by the three blades of the rotor. SMD components transform the interrupted signal into a pulse. SF800 Low Pressure Flow Meter Specifications * Flow velocity: 0.5 ~ 20 litre per minute * Temperature: -20 ~ +90'C * Operating pressure: 16 bar * Max. pressure: 40 bar * Power consumption: 12 - 36 mA/s * Material: PVDF, Vectra (rotor), Viton or EPDM * Output: frequencyPower consumption: 12 - 36 mA/s
SF800/6 - High Pressure Flow Meter The SF800/6 is the high-pressure version of the SF800 with extra metal enclosure. With an operating pressure of 250 bar and burst pressure of 750 bar, it is perfect for more demanding and high stress environments while retaining the versatility and other qualities of the SF800. The inside of the sensor is similar to the SF800, and is made of high-quality plastics and composites with great chemical and thermal resilience and no susceptibility to limescale. An integrated PCB emits the infrared signal, which is interrupted by the three blades of the rotor. SMD components transform the interrupted signal into a pulse.
