The DMA: Always superior

Jan 15 2024

Anton Paar has again expanded the limits of digital density measurement with the DMA 4101/4501/5001 density meters, which provide a new level of user confidence and comfort. New features give users complete confidence in the sample filling and measurement. Therefore, they know their measurement results are of high quality.

A range of features

FillingCheckTM (patent application filed) automatically detects filling errors or gas bubbles in the filled-in sample. It alerts the operator of potential measurement deviations and documents the incident.

U-ViewTM displays live images of the oscillating U-tube sensor and the entire filled-in sample. Potential problems with the sample can be reliably identified in real time or later since the images are automatically stored. This makes DMA 4101/4501/5001 instruments the first density meters to allow verification of results, particularly when using automatic sampling systems, at a later stage.

ThermoBalanceTM eliminates the need for multi-temperature calibrations and allows fast and accurate measurements in the entire temperature range over extended periods of time. It eliminates drifts caused by temperature stress, such as when filling samples at temperatures greatly different from the measuring temperature. DMA 4101/4501/5001 density meters are the only instruments to fully provide these capabilities.

Great accuracy

These density meters provide accuracies of 0.0001 g/cm³, 0.00005 g/cm³, and 0.000005 g/cm³. Their applications include the measurement of petroleum, petroleum products, fuels, alternative fuels as well as lubricants and crude oil. The instruments can be placed on-board a mobile lab or near the sampling location due to their compact design and stable measuring technology, which is unaffected by external influences. The intelligent condition monitoring system gives a warning and recommended action if the instrument´s environmental conditions are not in the ideal range. This minimises maintenance efforts and downtimes and maximises productivity.

With an accuracy up to the 6th digit (DMA 5001), these density meters outperform the requirements of ASTM D4052 for situations where unmatched accuracy is all that counts: think, for example, volume-to-mass conversion for account settlement.

The benchmark

These laboratory density meters are the benchmark for any fuel density measurement application and can be equipped with fully automatic sample changers for highest sample throughputs.
