Apparatus for use in measuring properties of media formed from a particulate suspension, the apparatus including:
- a media sampler coupled to feed pipes to allow media flowing therethrough to be sampled, wherein the media sampler includes an element having a plurality of apertures to allow media to flow therethrough whilst restricting particulate material to flow therethrough, wherein each aperture is an elongate slot which extends in a direction which is substantially parallel to the flow of the media through the feed pipes;
- and
- a connector for coupling the media sampler to a sensor for sensing properties of the sampled media, wherein the connector includes a pressure reducing outlet for reducing a flow pressure of the sampled media flowing therethrough to the sensor.
Apparatus for use in measuring properties of media formed from a particulate suspension, the apparatus including:
- a media sampler, the media sampler being coupled to feed pipes to allow media flowing therethrough to be sampled;
- and
- a connector for coupling the media sampler to a sensor arrangement for sensing properties of the sampled media, wherein the sensor arrangement includes:
- a sensing tube having an inlet coupled to the connector, wherein the sensing tube receives a constant flow of sampled media from the feed pipes;
- an outlet for returning sampled media, wherein the outlet is an adjustable orifice;
- and
- a differential pressure sensor positioned along the sensing tube to thereby determine the pressure of the constant flow of sampled media at different positions.
