FV102 OMEGA Vortex Shedding Flow Meter

FV100

The Omega FV100 Vortex Shedding Flow Meters 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

The Omega FV100-T Vortex Shedding Flow 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.
