Abstract
The present disclosure relates to a density meter for slurry which is transported through a pipe, the density meter may include a frame; a pipe part; flexible pipe couplings arranged between the frame and either end of the pipe part for coupling the pipe part to the frame and to a feed pipe and a discharge pipe; a first accelerometer arranged on the pipe part for measuring the accelerations of the pipe part; an actuator arranged between the pipe part and the frame for imparting force on the pipe; a controller for controlling the actuator; and a computing means having a mathematical model to ultimately calculate the density of the slurry in the pipe part.
Claims19
A density meter for slurry which is transported through a pipe, the density meter comprising:
- a frame;
- a pipe part;
- flexible pipe couplings arranged between the frame and either end of the pipe part for coupling the pipe part to the frame and to a feed pipe and a discharge pipe, in which the pipe couplings impart to the pipe part at least one degree of freedom relative to the feed pipe and the discharge pipe and relative to the frame;
- a first accelerometer arranged on the pipe part for measuring accelerations of the pipe part in a direction of the at least one degree of freedom;
- an actuator arranged between the pipe part and the frame for imparting a force on the pipe;
- a controller for controlling the actuator with a multi-frequency signal;
- and
- computing means having a mathematical model, wherein the computing means fit, in an operational mode, while the controller controls the actuator, the accelerations measured by the first accelerometer on the mathematical model to determine at least one parameter of the mathematical model and wherein the computing means calculate the density of the slurry in the pipe part with the determined at least one parameter.
