BeskrivelseThe FV100 Series vortex flow meters are inline flow meters that utilizes the vortex shedding measuring principle. The fluid strikes a bluff body which imparts alternating vortices downstream of the bluff which create a pressure on a sensor body containing a piezoelectric crystal. The frequency of the vortex flowmeter sensor is proportional to the velocity of the fluid and is amplified and converted to a 4 to 20 mA output linear with flow. Vortex technology yields a meter with no moving parts to hang up or wear. The meter has a bright 76.2 mm (0.3") high LED display of flow in either liters or gallons. It can be mounted with flow in any direction and the display can be rotated 180° in the field for viewing convenience. The FV100 Series vortex flow meter can be used on non-viscous, clean or dirty water-like liquids that are compatible with brass, PVDF and FKM. Metered fluids should not include long fibers or a significant level of abrasive solids. Typical applications will be for cooling loops using water or 50% glycols, and water soluble machine coolant (up to 10%). These applications are found in most process industries, including rubber, steel, fabrication, manufacturing, refining, paper, chemical, food, petrochemical and power. Do not use on flammable liquids or gases such as air.
