Liquistation CSF39

Summary

Product Identification

The Liquistation CSF39 is an automatic stationary sampler for liquid media, featuring self-draining capabilities and an integrated controller. It supports up to two measuring channels and optional digital Memosens technology.

Applications

The CSF39 is designed for fully automated sampling, defined distribution, and temperature-controlled storage of liquid media. Typical applications include:

• Communal and industrial wastewater treatment plants
• Laboratories and water management offices
• Monitoring of liquid media in industrial processes

Key Features and Benefits

• Four different housing material options.
• Two-door housing for reliable sample temperature regulation with air circulation in both upper and lower enclosures.
• Fast menu guidance, navigator, and a large display.
• Practice-oriented programming.
• Modular platform for functional extension.
• Integrated data logger.
• Service interface for data transmission.
• Optional battery backup system for uninterrupted operation.

Device Principle

The sampler operates using either a vacuum pump or a peristaltic pump.

Vacuum Pump Operation:

1. Blow clear: The suction line is cleared using the vacuum pump.
2. Intake: The sample is drawn into the dosing beaker until it reaches conductivity probes for level detection.
3. Dose: Excess sample liquid flows back to the sampling point based on the dosing tube position.
4. Drain: The sample is drained into the sample bottle.

Peristaltic Pump Operation:

1. Rinse: The pump runs in reverse to flush the suction line.
2. Intake: The pump runs forward, drawing the sample. Volume is automatically calculated based on flow and medium detection.
3. Drain: The pump runs in reverse to return excess medium to the sampling point.

Level Detection

• Conductive Dosing System: Utilizes three conductivity sensors to detect sample level. Sensor 2 acts as a safety backup.
• Capacitance Dosing System: Employs a capacitance sensor that detects changes in the liquid level. This method is effective for foaming media, high-fat content media, and media with conductivity <30 µS/cm.

Sampling Unit Configuration

A complete sampling unit includes:

• Controller with display and controls.
• Vacuum or peristaltic pump.
• PE sample bottles (2 x 15000 ml) with self-emptying function and automatic cleaning.
• Optional sampling chamber temperature regulator.
• Suction line with suction head.
• Distribution arm.
