Fluidwell - Model F120 -Field Mount - Flow Rate Controller with Analog Control Output and High / Low Alarms
FromFluidwell bv
The F120 single loop controller has been designed to offer outstanding control performance and provide a reliable solution for a wide variety of flow control applications. The single loop flow controller accepts most pulse inputs from flowmeters and has a 4 - 20 mA output for controlling a valve or pump. The F120 is part of the Fluidwell process controller family and is the alternative for local control loops.

- Robust IP66, IP67 (NEMA Type4X) field enclosure. It is so rugged, you can even stand on it!
- Intrinsically Safe available - ATEX and IECEx approval for gas and dust applications.
- Programming can be done by your own crew, with the sensible menu-driven structure, saving cost and irritation. Know one, know them all!
- Very diverse mounting possibilities: walls, pipes, panels or directly onto outdoor sensors.
- Two control modes:
- Hand (manual valve control)
- Auto (control flow to obtain the desired flow rate)
- Bumpless transistion between the control modes.
- Flow rate monitoring: two alarm values can be set: low and high flow rate alarm.
- Alarm values can be changed by the operator or they can be password protected.
- Safety mode input to place the valve in a safe position
- Flow rate: seven 17mm (0.67") digits.
- Total - resettable: seven 17mm (0.67") digits.
- Displays clear alarm messages.
- LED backlight.
- Auto backup of settings, totalizer value, setpoint and control mode in EEPROM memory.
- Ambient temperature: -40°C to +80°C (-40°F to 176°F).
- Various accessories are available for this product.
- The F-Series is so rugged, even a truck can stand on it!
- The F-Series is your first and best choice for field mount indicators in safe and hazardous area applications. Especially in harsh weather conditions like rain, snow, salty atmospheres and temperatures between -40°C up to +80°C (-40°F up to 176°F).
- Applications where a constant liquid or gas flow is desired without the need to manually control the flow.
