HOW IT WORKS

The FV100 is an inline flow meter 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 sensor is proportional to the
velocity of the fluid and is amplified and converted to a 4-20mA output linear with flow. Vortex tech­nology yields a meter with no moving parts to hang up or wear.

The meter has a bright .3 inch 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 degrees in the field for viewing conve­nience. The meter requires a nominal 24 VDC power source and outputs a visual display of flow, as well
as 4-20 mA proportional to flow, and a field settable solid state relay for low flow alarm conditions. The
meters come pre-calibrated for the specific range as determined by size. The turndown is 10: 1 and the
accuracy is better than 5% of full scale flow.
