Since the launch of the Forced Oscillation Method by Anton Paar in the 1960s, a constant oscillation of the U-tube has been the state of the art. In this method, the U-tube is forced to oscillate continuously at its characteristic frequency. Over the years, continuous improvements like viscosity correction of the measured results and filling error detection were implemented. However, this technology has reached its limits. In order to advance, Anton Paar’s dedicated research team has rethought this technology from scratch.
The heart of a modern digital density meter is the measuring sensor, a U-shaped tube made from borosilicate glass or metal. It is excited to oscillate at its characteristic frequency, which is directly related to the density of the sample.
The new patented Pulsed Excitation Method (PEM) redefines digital density measurement. After reaching a stable oscillation, the excitation is switched off and the oscillation fades out freely. This sequence of excitation and fade-out is repeated continuously, creating a pulsing oscillation pattern. By allowing the natural oscillation of the U-tube, and evaluating this oscillation pattern, the instrument gains three times more information than with the conventional Forced Oscillation Method.
After Anton Paar’s re-invention of digital density measurement, there are now two excitation methods on the market: conventional and new.
People with or without working knowledge digital density meter and are interested to know more about the instruments’ application and benefits.
