The F124 ratio controller has been designed to ensure that two flows are kept at the same ratio even if flows are changing. The Fluidwell ratio controller will show a strong influence of maintaining a good and constant quality of products and saves money on the blending components. The F124 is a key product of the Fluidwell Process Controller family and is the alternative to replace existing pneumatic controllers in local control loops. Advantages
Robust IP66, IP67 (NEMA4X) 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.
Features
Calculates and controls the ratio between flow A and flow B. Formula: ratio = additive / main
Three control modes: - Hand (manual valve control) - Local Setpoint (control additive flow only) - Ratio (control additive flow to obtain the desired ratio).
Bumpless transistion between the control modes.
Displays actual and desired ratio simultaneously, flow rate A and flow rate B.
Safety mode to place the valve in a safe position
Analog output to control the position of the valve.
Ratio: seven 17mm (0.67") digits, displayed as percentage. Desired ratio: five 8mm (0.31") digits.
Flow rate A and B: seven 17mm (0.67") digits.
Ratio monitoring: two alarm values can be set: low and high ratio alarm.
Displays clear alarm messages.
Green LED backlight.
Auto backup of settings, setpoint and control mode in EEPROM memory.
Ambient temperature: -40°C to +80°C (-40°F to 176°F).
