ABSTRACT:
An improved apparatus for sensing and measuring the flow of dry particulate materials including a sensing device (20C) connected to a remote measuring device by a coaxial cable (25). The sensing device (20C) has a probe (24) defining an electrode which may be positioned within a flow line (18). Particles passing over the probe (24) produce a measurable electrical charge to the probe (24) due to the triboflow effect which may be transmitted to a remote measuring device by a coaxial cable (25). A shield (40) envelopes the probe (24) in a telescoping relation and comprises a wire mesh screen, which permits the flow of dry particulate material over the probe (24) while restricting stray electrical interference and electromagnetic radiation to the probe (24).
