Flow Controllers
Universal Flow Controller
UFC 0620 000
The Accumax Universal Flow Controller is a compact flow measurement and control unit used in laboratory and industrial settings to measure and read flow rates. It communicates with flow measuring devices over RS 485 and is set up from the front panel, where a display and push buttons are used to select modes, measurement units and timer.
How it works
Reads flow data from connected flow measuring devices over RS 485 serial communication and presents/controls it through a local display and push-button configuration; the page does not state the electrical input type or control output.
Features
-
Serial communication using RS485
Communicates with flow measuring devices over RS 485.
-
Five operating modes
Source says it 'can operate using 5 modes'. The five modes are never named anywhere on the page.
-
Flow controller / monitor functionality
Stated as both controlling and monitoring flow.
-
External push-button
Provision for an external push-button.
-
Password protection configuration
Configuration can be password protected for safer operation.
-
Display and push-button configuration
Front-panel selection of modes, measurement units and timer.
-
Completes batch even when a power interruption occurs
CAUTION: this bullet is in the product's own feature list but is copy-pasted batch-controller wording; confirm with Accumax that the UFC really has batch-resume behaviour before publishing it.
Operating modes
- Totalizer
- Monitor current flow and totalised volume.
- Batcher
- Dispense a set batch of liquid.
- Flow comparator
- Monitor two flow sensors (inlet vs outlet) and alarm on a reducing rate of recovery.
- Rate Switch
- Monitor current flow and alarm on crossing a preset threshold.
- Pulsar
- Trigger a task on completion of a preset volume — dosing applications.
- PID controller
- Control flow using a 4-20 mA output.

9 further specification s are listed in the datasheet but not reproduced here
These labels appear in the datasheet, but the value beside them could not be read reliably from the document. Rather than print a figure we cannot stand behind, we have left them out — ask us and we will confirm them directly.
- Switch numbering in the Software Settings table — printed "Switch1 / Switch__ / Switch__ / Switch__"; only the first number survived
- Hardware version on the first connection drawing — printed "5.1 Version 1." with the minor digit lost (the second drawing reads "5.1 Version 1.0")
- Separator between the PID mode's current-loop endpoints — printed across a line break as "4" then "20mA"
- Terminal designation for the negative RS485 Modbus line — the label reads only ": RS485 MODBUS (" with the D- and the minus sign lost
- Deviation setting — printed "DEVIATION (+/" with the closing text and any range lost
- Supply voltage range — no supply-range spec row exists anywhere in this manual (only the "230V AC" nameplate caption)
- No environmental specification (operating temperature, humidity, IP rating) appears anywhere in this manual
- No enclosure dimensions, mounting, or weight appear anywhere in this manual
- No accuracy, flow range, or display resolution specification appears anywhere in this manual
