Aalborg, TIO-LAA2, Totalizer Controller with LCD Display & Keypad, Input/Output 0-5 VDC RS232 Interface
Display
The graphical LCD display has large 13 mm (0.51") digits for flow rate and 5.5mm (0.21") for total and can be set by user to simultaneously show different combination of the flow parameters: flow rate, totalizers, flow alarms, and diagnostic events. All configuration parameter set-tings are easily accessed via a simple user-interface menu driven by a 6 button key-pad which can be password-protected.
Programmable Pulse Output
The programmable flow pulse output is operating independently from totalizers and based on configuration settings can provide pulse frequency proportional to instantaneous fluid flow rate.
The LCD/keypad and digital communication interface commands are provided to:
- Enable/Disable Pulse Output
- Configure Pulse Output start flow rate (in % of full scale)
- Configure the Unit/Pulse value (in current volumetric or mass flow units)
- Configure Pulse Active On Time (10 - 6550 ms)
Programmable Alarms
TIO provides the user with a flexible alarm/warning system that monitors the fluid flow for conditions that fall outside configurable limits as well as visual feedback for the user via the LCD or via an optically-isolated output. The flow alarm has several attributes which can be configured by the user via LCD/Keypad or digital communication interface:
- Enable/Disable flow alarm
- Low flow alarm settings (in % of full scale)
- High flow alarm settings (in % of full scale)
- Flow alarm action delay
- Flow alarm action latch mode
Digital Communication
All process data and settings can be read and modified manually via local LCD Key-pad or through the digital communication interface. Proprietary ASCII software interface command set and free Communication Utility software are provided.
Features:
- Displays instantaneous, total and accumulated flow rates.
- Built-in Flow Linearizer (10 point linearization of the flow curve).
- Up to 47 different volumetric and mass flow engineering units.
- Large 13 mm (0.51") digits for flow rate and 5.5mm (0.21") for Total.
- Compact design for unit mount, panel mount, wall mount or field mount applications.
- User-programmable, optically-isolated pulse output.
- Two programmable, optically-isolated, digital outputs.
- Flow controllers, set point command control via local LCD or digital interface.
- Programmable set point table with ramping up/down capability up to 16 steps.
- Free Configuration and Monitoring Utility software.
Application:
- For flow meters and controllers with analog, input output interface, where flow indications / control and totalizers or alarm functions are required.
- Also when re-transmission of the flow rate and/or totalizer functions via optically-isolated pulse output or serial communication is desired.
- Local or programmable set point control for flow controllers (no host PC presence required).
- Activation of user-supplied equipment via programmable optically isolated digital outputs when flow alarms or totalizers events are active.
