A viscometer includes first and second capillaries and a valve. In a first state, the valve connects the second capillary to a first fluid injector via the first capillary. In a second state, the valve connects the second capillary to a second fluid injector. A controller receives data indicative of respective pressure drops within the first and second capillaries, and generates a pressure ratio signal therefrom. The controller analyzes the pressure ratio signal to determine an end of a transition between a first equilibrium when the valve is in the first state, and a second equilibrium when the valve is in the second state. The controller defines a measurement window based on the transition end, and therein determines a viscosity of the second fluid based on the pressure ratio signal. The first fluid is a solvent, and the second fluid is a solution of a same solvent and a solute.

A dispensing system for dispensing hot melt adhesive foam onto a substrate is described. The dispensing system comprises a pump having a first input to receive a hot melt adhesive and a second input to receive a gas, where the pump mixes the hot melt adhesive and the gas to produce a solution and pump the solution at a volumetric flow rate. The dispensing system also includes a valve to control an amount of the gas provided to the pump from the second input, a flow meter to measure the volumetric flow rate of the solution pumped by the pump, and a dispenser to receive the solution from the pump and dispense the solution to create the hot melt adhesive foam.

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.
