Measurement of the amount and speed of a material flow in pipes or tubes

SeeDector deploys a novel technique for measure­ment of amount and speed of a flow of particulate material (e.g. seeds, mineral fertilizer, granules) or liquids moving in pipes. For many applications - e.g. seed drills, fertilizer applicators, slurry injectors - the amount and speed of a material flow becomes measurable first time, real-time in the process. SeeDector is the seed blockage sensor in the SeedMon system.

SeeDector is a material flow sensor based on high-frequency electro­magnetic waves (microwaves, doppler radar). SeeDector is directly clamped onto a tube or pipe without alterations. Measure­ment data are transferred via CAN-Bus.

The SeeDector technique has been applied for German and European patent. USA Patent (US 8,915,144 B2) has been granted.

At the Agritechnica 2011 fair SeeDector has been awarded with a silver medal from the DLG novelties commission.

SeeDector data sheet here and further details on request.

• Throughput measure­ment of a free falling or peumatically conveyed flow of particulate material or liquid.
• Covers the range from smallest (e.g. oilseed rape, gras) to the biggest kernels (e.g. beans, peas).
• Enabling and optimising monitoring, control and closed-loop control.
• Easy and simple installation, clamped with a sheet steel bracket on a plastic pipe (possibly with metal spiral inlay) or placed in a cut-out window of a metal pipe.
• No cutting or alteration of a plastic pipe.
• Nothing built into the pipe constricting the material flow.
• No alteration of the machine´s design.
• By virtue of the functional principle (doppler radar) unsusceptible against dirt, dust or incrustation inside of the pipe - contrary to all other functional principles of the competition.
• Smart sensor with integrated processing and communication (mikro­controller).
• CAN interface for output of amount and speed of the material flow.
• Enabling blockage monitoring systems detecting partial blockage with decreased throughput.
• Enabling monitoring and detection of flow switching on and off when tramlining.
• For installation on pipes or tubes with different diameters a wide range of sheet steel brackets with according dimensions is available.
