Density Meters

Based on the principle of the oscillating U-tube, density meters are used for a wide variety of applications within the food, chemical and petroleum industries. Samples to be analyzed are filled into a glass U-shaped tube, which is then induced to vibrate. The frequency in which the U-tube oscillates is directly related to the mass, and therefore density, of the sample. Samples with a higher density will exhibit lower oscillation frequencies compared to samples of a lower density. With measurements performed at an ambient pressure and moderate temperatures, density meters produce accurate measurements in a short period of time with minimal sample volume required.
