Overview

The document describes the TeknaEVO 500 series "Low-Flow" dosing units designed for precise dosing of small volumes while maintaining consistent stroke numbers and guaranteed quality under various counterpressure conditions.

General Features

• Available in multiple interface versions: AKL and TPG.
• Two main interface types: analogic and digital.

Interface Descriptions

Analogic Interface

• Constant flow rate manually adjustable.
• Two frequency ranges (/5).
• Power-ON LED indicator.
• Level control input.

Digital Interface

• Constant flow rate manually adjustable.
• Proportional flow rate control based on external analog (4-20 mA) or digital signals (e.g., water meter).
• Timer function for dosing control.
• PPM proportional dosing capability.
• Statistics tracking.
• Password protection.
• Remote On-Off input control.

Performance Characteristics

The document includes a performance graph illustrating the relationship between flow rate (liters per hour) and pressure (bar). The flow rate ranges from 0 to approximately 3.5 lt/h, while pressure ranges from 0 to 20 bar, indicating the unit's capability to maintain dosing accuracy across these parameters.

Applications

While specific applications are not detailed, the unit is implied to be suitable for dosing small volumes accurately in various industrial or laboratory settings requiring precise flow control.

Critical Information

• Reduction of unit volume allows maintaining stroke number unchanged, ensuring dosing precision.
• Quality is guaranteed across all exercise counterpressures.
• Multiple control options (manual, analog, digital) provide flexibility for integration into different systems.
