The wet portion comprises the density from all liquids present in the sample.
A density meter does not measure the specific gravity of a sample directly.
The specific gravity is found by the following equation: Where: Density meters come in many varieties.
Different types include: nuclear, coriolis, ultrasound, microwave, and gravitic.
Density meters are used to measure slurries, sludges, and other liquids that flow through the pipeline.
Industries such as mining, dredging, wastewater treatment, paper, oil, and gas all have uses for density meters at various points during their respective processes.
This twisting causes phase shifts which result in changes in the resonant frequency of the thin walled tube.
Higher density media causes a larger Coriolis effect if the volumetric flow rate is constant.
Nuclear density meters work on the principle of measuring gamma radiation.
Therefore, the density of the media is inversely proportional to the radiation captured and seen by the scintillator.
Nuclear density meters are limited in scope to what is seen by the gamma radiation beam.
The sample size is a single, thin column with small longitudinal length.
Nuclear equipment requires certified and licensed staff in order to operate the instruments.
[1] Microwave density meters have various ways to measure what solids are in the sample.
[2] Some microwave meters use a ceramic probe that is directly inserted into the sample.
The percentage of solids of the slurry affects the dielectric constant for the entire sample.
The ultrasonic density meter calculates the sonic velocity by using the known distance between the transmitter and receiver and the measured transit time.
The measuring instrument can now calculate the density, as it is dependent on the sound velocity.
Doppler ultrasonic meters measure the suspension flow where the concentration of solids in the slurry is above 100ppm and the particles that are suspended are larger than 100 microns in diameter.
These damages typically cause offsets that can be added to the existing calibration factors that will ensure that a consistent reading is still acquired.
