Quality assurance of automated measuring systems (AMS)
Quality assurance of automated measuring systems (AMS) ensures that your plant meets the existing environmental requirements and may entail savings in your tax payment.
Ensure correct tax payments and compliance with requirements
If you have an automated measuring system (AMS) at your plant, you are obligated to carry out quality assurance within a defined time frame. If you do not meet regulatory requirements for quality assurance of AMS, you risk losing the right to operate the plant.
Further to that, you must uphold the rules on quality assurance of AMS required from the tax authorities, who may fine you or issue elevated taxes due to lack of compliance.
We can ensure that your automated measuring systems are adjusted correctly and according to current legislation. This way you will avoid incorrect measurements of e.g. NOX, sulphur and carbon dioxide, while at the same time ensuring correct tax payment.
Quality assurance of AMS with FORCE Technology
We provide consultancy, measurements and courses regarding quality assurance of AMS. With us on the task, you can feel confident that your system upholds all required standards.
- hold many years of experience in the field of air emission monitoring
- have a large staff of experienced air pollution specialists and sampling technicians
- have broad and updated knowledge on environmental legislation and norms
- have a wide range of instruments including measuring equipment for more specialised tasks
- are accredited by DANAK.
Within quality assurance of automated measuring systems we offer to:
- prepare measuring programmes, which ensure that requirements in standards and legislation will be met and fulfilled
- perform parallel measurements and supply a complete QAL2 or AST report, ready for submission to the local authorities
- provide counselling on QAL3 issues or carry out a complete QAL3, including practical performance and documentation.
Planning ensures quality and minimises costs
FORCE Technology holds accreditations for all relevant parallel and environmental measurements required from the Environmental Committee. The extent of measurements are often large, and we optimise our planning in close cooperation with you so that the work may be performed efficiently with regards to both time and cost.
We draft a plan for measurements in collaboration with our clients. Our sampling technicians take immediate action in situations when the requirements for parallel measuring have not been met. Our aim is to avoid wasted hours, repeated work and costly re-measurements for you as a customer.
Supplementary environmental measurements
Performance measurementsThe parameters that cannot be measured by AMS (e.g. trace metals and dioxins), must be carried out as performance control measurements. In connection with performing parallel measurements for quality assurance of AMS, we also perform other measurements required by the authorities. By bundling your measurement services, you may reduce the total costs for measurements.
O2 and H2OThe DS/EN 14181-standard has no specific requirements for the quality of the facilities' own measurements of e.g. O2 and H2O. Since O2 and H2O are generally very important parameters for, among others, the operation of the plant, we offer measurement of these peripheral AMS, together with the regular parallel measurements.
Homogeneity testAccording to DS/EN 15259, all AMS sampling sites must be tested for homogeneity (i.e. whether the gases have been mixed homogeneously). Wa can perform the homogeneity test in connection with QAL2 or AST parallel sampling, thereby reducing the overall cost.
Test of data acquisition and handling systems (DAHS)We also offer to carry out a test of the DAHS, where we determine whether AMS signals are led correctly to the computer. We test all calculations of e.g. normalisation, correction for oxygen, averaging, etc. We also test the system ability to count ELV-exceedings, etc. The test will secure that your environmental report and tax payments are correct.
Please contact us if you wish to learn more about quality assurance of AMS, or you want to get started with quality assurance.
How should a QAL2 calibration function be?
A QAL2 calibration function should always have a slope close to 1.0 and an offset close to zero. When this is not the case, there is often something wrong with either the AMS or the sampling site.
The variability test at QAL2 and AST may be passed with QAL2 calibration functions far from the expected. A passed QAL2 or AST is not guarantee that the AMS and the sampling site are ok.
Why is flow AMS important?
Flow AMS needs quality assurance from parallel measurements, etc.
Flow is a very significant parameter in all measuring based tax payments (e.g. NOX, SO2 and CO2).
In 2013, two new European norms on parallel measurements and flow and quality assurance of flow AMS were published (DS/EN 16911-1 and DS/EN 16911-2). The norms require that the calibration function must be performed in velocity (m/s), and that the duct area applied in the flow calculation, must be checked by a new measurement of the duct area during QAL2.
The correct duct area should always be applied in the flow calculations.
