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 applica­tions 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.

USING THIS MANUAL
To use this manual, you will require the model code, which can be found on the nameplate of the meter, as shown on the example below. See page 10 for “Model Codes.” The Model Code will allow you to determine the minimum & maximum flow capabilities for each as well as related pressure drops.
All FV100 or FV100-T meters are equal in terms of features and functions. The only difference is the flow capacity of the various sizes.

INSTALLATION
There are no upstream or downstream piping requirements to achieve the operating specifications given herein. The meters may be installed in any position as long as good piping installation requirements are adhered to for best results. This includes proper support of adjacent piping to minimize inherent vibra­tions produced within the system. Unions of the same pipe size and full port isolation ball valves may be installed for ease of removal and servicing of equipment, if required. Meters should be placed in hori­zontal, slightly ascending runs or vertical runs to prevent entrained air from accumulating in the meter. They should not be placed at the highest point in the piping for this same reason. Piping system should be filled slowly to prevent water hammer from damaging sensor. The meter sensor can also be damaged by reverse flow.
Isolation ball valves, when used, should be in the full open position. Throttling valves should always be placed downstream of the meter, a minimum of 10 pipe diameters downstream.
Teflon® tape or pipe sealant can be used in mounting the meter to the piping when using good technique. Teflon® tape, if not applied properly to the connecting piping, can become caught on the bluff and affect
the flow measurement.
Use of diaphragm or piston pumps will affect metering performance, unless they are installed with a properly sized pulsation dampener and pressure control valve, to minimize pulsating flow. The piping system must create some backpressure on the meter to allow vortex formation and to prevent cavitation, especially at full flow. Minimum required back pressure is 10 PSIG at max flow and 70° F (21° C). Higher back pressures are required at elevated temperatures and occasional surges to 125% of max flow.
This situation will not be encountered in most installations. If while increasing the flow, the signal or displayed flow appears to drop off, but reappears when flow is reduced, contact OMEGA to determine back pressure requirements to extend the flow range to the capacity of the meter.

CONFIGURATION (Setup)
FV100 comes pre-calibrated and pre-configured in Gallons Per Minute, with the Solid State Relay set
for 0 flow, which inactivates the relay. To change the engineering units displayed to LPM, reset the solid state relay for a minimum flow condition, or change the relay function (nc-normally closed or no­normally open) requires a simple reconfiguration. By powering up the meter, it can be reconfigured or checked at the bench or installed position.
To configure the FV100 display for GPM or LPM, press the SET button so that the LED next to the desired engineering unit is lit. To configure the set point, or alarm function, hold the MENU button down until the display indicates “flo”, then “AL”, then release it. The LED display will indicate zeros or a set point. Change the setting, by pressing the MENU button. Each time it is pressed, it will step the set point upwards, holding it down will ramp the set point up quickly until the desired set point is ap­proached, then pressing discreetly will step it up to the desired setting. At the highest setting for each meter capacity, it will roll over to 0. Then as the MENU button is pressed it will step or ramp up if held down. Once the desired set point is displayed, use the SET button to enter the value.
If no set point is required, then select 0 with the SET button - this will inactivate the relay, as well as the local LED indicator, which flashes on reaching the set point. The two LED indicators that are adjacent to GPM & LPM flash when the flow drops to or below the set point. If GPM has been selected, it will remain on solid and the LPM indicator will flash. The opposite occurs when LPM is the selected unit of measure displayed.

CONFIGURATION (Setup) continued...
The next parameter, relay function, will automatically appear. It may indicate “nc”, normally closed, or “no”, normally open. Pressing the MENU button will change the relay function from one to the other. To select the desired relay condition, merely press the SET button. The relay function selected is at the normal flow condition, above set point. So, by selecting “no”, the relay will be open above the set point and close on reaching the set point or lower. Conversely, if “nc” is selected, the relay will be closed above the set point and open at or below set point.
Once the relay function is set, the meter will return to the run mode. If no flow is present, the meter should display zeros and the LED adjacent to the unit of measure not selected will be flashing to indicate a low flow condition (unless a set point of zero was selected).
FV100-T includes the features of FV100 plus temperature. FV100-T has a second set of LED’s adjacent to the SET button. One is labeled F, for degrees Farenheit, and the second C, for degrees Celcius.
To setup the flow portion of FV100-T, the flow variable must be displayed. Pressing the MENU button one time, toggles between the displayed variables of flow and temperature. Press the MENU button once if temperature is the displayed variable. Then complete the setup for the flow variable as, described above under FV100.
To configure the temperature portion of FV100-T , press the MENU once, if the temperature variable is not displayed. Temperature, since it is being measured on power up, will be displayed as degrees F or C dependent upon the status of the LED indicators adjacent to the two units of measure. To enter a set point, hold the MENU button down until “t”, then “AL” are displayed, consecutively. The display will then indicate the set point. To change, press the MENU button to step the value upward, or hold the MENU button down to quickly ramp up the setting, releasing as the desired value is approached, and then pressing incrementally until the set point is reached. Then press the SET button to enter the se­lected value. Again, as in the flow set point, if the set point is passed, continue holding the MENU button down and it will roll over to zero and continue increasing until released and incremented slowly to the desired value. After selecting the set point the meter will return to the run mode.**
**NOTE: The relay function for temperature is the same as selected for flow. If the “nc”, normally closed condi- tion is selected for flow, it will also function the same way for temperature. The relay function (status) is always at the normal condition. So, if “nc” is selected, the relay will be closed above the flow set point and below the temperature set point. That is because we are normally looking for a low flow condition and a high temperature condition in cooling applications. When either set point is reached for flow or temperature, its respective relay will change state. The set points, when selected in either GPM or LPM and F or C, will automatically con-
vert to the correct value, if the other unit of measure is selected.

FV100-T LED Indicators
The LED’s adjacent to the engineering units of GPM, LPM, F, & C have two functions. The first is to indicate the process variable being displayed and its respective engineering unit, the second to indicate alarm conditions. If temperature is being displayed, say 75 F, then 75 will appear in the display and the LED adjacent to F will be lit. If the temperature would increase to its respective set point, then the actual value will be displayed, the F LED will remain lit and the LED adjacent to C would begin flashing. If, at the same time, there is a low flow condition, both LED’s next to GPM & LPM will also flash - indicat- ing a flow fault also, so that you can press the MENU button to verify the flow rate.
In either case, if flow or temperature is the displayed value, when a fault condition occurs on the nondisplayed value, the two indicator LED’s associated with that variable will both flash to provide a local indication of a fault. The solid state relays will still function independently, also regardless of the variable being displayed. As will the 4-20 mA outputs.
