Toshiba Insertion LQ300 Microwave Density

Toshiba's LQ300 Microwave Density Meter uses a new principle, microwave phase difference measurement, to determine the density of fluids flowing through pipes.

This exploits the way a fluid's density affects the propagation of microwaves when they pass through it.

This allows the reliable measurement of the fluid's density by monitoring the difference in microwave phase between the original wave and one passed through the measured fluid.

Unlike the method that depends on monitoring the attenuation of a transmitted wave, measuring fluid density by observing a wave's phase difference is unaffected by flow velocity and/or is not affected by the contamination and/or bubbles
