Embodiment Construction

[0027] Such as figure 1 An example of a possible probe for obtaining the rheological properties of concrete inside the mixer 2 of a mixing truck is shown in . figure 1A side view of the truck is shown and a probe 10 inside the mixer 2 is shown schematically, which is used to obtain rheological property information. It can further obtain information such as mixing speed and direction, fluid mobility, fluid temperature, which will be explained in detail further below. Due to the difficulty of introducing a wired connection within a stirred vessel, the probe transmits data to the receiver 3 via a wireless connection and the probe is self-powered. In mixer trucks, the axis of rotation 6 of the mixer is strongly inclined relative to the vertical.

[0028] According to this embodiment, the concrete will be used as a reference as the substance being rheologically characterized; however, the probe can be used in another container or receiver than the mixer 2, whether rotating or not...

Abstract

The probe can include a base and a resistance member extending from the base and onto which a resistance pressure is imparted by a rheological substance when the resistance member is submerged and moved therein. Rheological properties can be obtained using values indicative of the resistance pressure both in a low speed range and in a high speed range.

Description

[0001] Cross-references to related applications / prior claims [0002] This application claims US Provisional Application No. 61 / 249,321, filed by applicant on October 7, 2009, the contents of which are hereby incorporated. Background technique [0003] Fluidics is the study of flowing substances. The invention is particularly concerned with the flow of soft solids which exhibit liquid-like behaviour. Many applications can benefit from or even require the measurement of a substance's rheological properties, especially if this property changes over time. [0004] Concrete is a good example. Once mixed, the concrete is usually mixed continuously in a mixer to prolong its life before setting. The mixer is usually mounted on a truck. However, even though a mixer prolongs the life of the concrete, this does not make it last indefinitely, and the rheological properties of the concrete inside the mixer, such as viscosity and yield, can change over time. For this reason, a common te...
