OPERATION
FV100 is an inline flow meter that utilizes the vortex shedding principle. The fluid strikes a bluff body
generating vortices (eddies) that move downstream. The vortices form alternately, from one side to the
other. A piezoelectric sensor housed in a sensor tube directly downstream of the bluff senses the pressure
zones created by the vortices. The sensor generates a frequency directly proportional to the vortices
(flow). The pulses are then amplified by the circuit board and converted to a 4-20 mA output, which is
also linear with flow. Flow can be displayed on the LED display in either GPM or LPM. Selection of the
preferred units of measure is made from two white front panel push buttons. There is also a solid state
relay output that can be set for a low flow contact from 15% to 90% of full-scale flow. The relay can be
configured to be NC (normally closed) or NO (normally open) at flow (above set point). It will change
state on decreasing flow upon reaching the setpoint.
FV100-T meters combine temperature measurement with the flow measuring features of FV100 Series.
The housing utilizes a temperature sensor housed in a small thermowell directly downstream of the flow
sensor. FV100-T meters display temperature or flow on the LED display. Temperature can be displayed
in either degrees Fahrenheit or Celsius and is selectable from the two white front panel buttons. There is
a 4-20 mA output proportional to temperature and a solid state relay that can be configured for a high
temperature set point. The relay function will be the same as selected for flow, normally closed or
normally open, below set point, since it is a high alarm. So, you have two transmitters in one - flow and
temperature.
APPLICATIONS
FV100/FV100-T can be used on low viscosity clean or dirty water-like liquids that are compatible with
brass, PVDF & Viton. Metered fluids should not include long fibers or a significant level of abrasive
solids. Bluffs are replaceable, as are the sensors, should abrasive wear occur over time. Typical applica-
tions will be for cooling loops using water, 50% solutions of 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. They cannot be used on
flammable liquids or gases including air.
NOTE: If this equipment is used in any manner not specified herein, the protection provided by the
equipment may be impaired.
Cleaning: These meters do not require any special cleaning of the external surfaces. If cleaning is
desired, do not use any strong solvents, detergents, or chemicals. Brushing away accumulations of dirt
or wiping with a cloth and water is suggested.
