FV100 Series of inline flowmeters

The FV100 Series consist of inline flowmeters that use the vortex-shedding measuring principle. When fluid strikes a bluff body, it imparts alternating vortices downstream of the bluff. This creates a vibration on a sensor body that contains a piezoelectric crystal, whose frequency is proportional to the velocity of the fluid, and is amplified and converted to a 4–20-mA output signal. The FV100 Series has no moving parts and features a bright LED that displays flow in liters or gallons. It can measure flow in either direction and can be used with non-viscous, clean or dirty water-like liquids. The FV100 series is ideal for use in cooling loops that use water or 50% glycols for up to 10% water-soluble machine coolant.
