Liquid analysis with high dissolved gas content

To be trust with measurement

FSPL-1-F-03PHOL10D

This sampling panel is designed for working with liquids, specifically ozone-saturated liquids. Its primary objective is to dissolve the actual ozone concentration and disperse bubbles that can affect measurement accuracy.

Description:

Measurement in liquids is not as simple as it seems at first glance. The homogeneity of the medium plays an important role. There are 2 main methods that are used to dissolve gases and thus create a homogeneous medium:

- Backpressure and holding time.
The pressure breaks large bubbles (gas is a compressible medium). Time is necessary for dissolution and splitting because in reality all processes are not lightning fast and have a certain inertia.
The pressure is achieved by means of a control valve, which reduces the nominal outlet diameter and creates a so-called back pressure.
The holding time is a parameter that is calculated for each process separately, taking into account the gas saturation level, type of liquid, etc. The dwell time is influenced by the length of the pipeline to the measuring point and the flow rate.

- Low temperature
At low temperatures, the solubility coefficient increases.

Panels modifications

This series of panels is designed as a universal solution that allows the analysis of parameters such as:

- Nitrogen (N2)
- Carbon dioxide (CO2)
- Hydrogen (H2)
- Oxygen (O2)
- Ozone (O3)

The panel series has 3 main modifications depending on the input conditions and analyzed parameters.

Our engineers have designed various solutions:

FSPL-1-F-03P0D
A simple version without a holding tube.

FSPL-1-F-03PHOL10D
Version with single level holding tube.

FSPL-1-F-03PHOL20D
Version with two-level holding tube.

Each modification has the possibility of easy integration into the system.

Compatible sensors

Dextens is a fast-growing Swiss company specializing in measuring equipment. This sampling panel is compatible with the following types of sensors:

1. EC (Electrochemical) Sensors:
Electrochemical sensors are used to measure concentrations of oxygen (O2), ozone (O3), etc. For more information, please refer to this article.

2. TC (Thermal Conductivity) Sensors:
Thermal conductivity technology, based on measuring the thermal conductivity of gases, is currently the most accurate method due to its immunity to interference from other gases. Typical applications are hydrogen (H2), nitrogen (N2) and carbon dioxide (CO2), but other also possible.

Flowmeter and its purpose:

The integration of the VA Flowmeter aims to precisely control the flow rate in the system. Flow control plays a key role in analytical measurements. Flow control allows the use of a stabilized measurement environment, which directly affects the accuracy of the measurement.

Advantages:

The panel ensures precise measurement in accordance with the manufacturer's stated accuracy through process stabilization.
Thanks to fine adjustments, this panel can operate reliably even with the presence of significant fluctuations in the measured medium. The use of a VA flowmeter allows for accurate configuration of the flow recommended by the manufacturer.
This solution easily integrates into a sampling system and allows for the connection of other analyzers and the expansion of connection points for automated monitoring from multiple locations.
The holder's length can be increased depending on the gas concentration.
Compatibility with CIP/SIP (Clean-in-Place/Sterilization-in-Place) processes.
