Abstract
A robust low-cost wireless sensor with an internal battery, which permits operation for extended periods without the necessity of maintenance, for monitoring the flow of particulate solid material such as chemical fertilizers, small seeds, granulated foodstuffs, and others.
Claims23
A wireless particulate solid material flow sensor with an internal battery, comprising:
- a rigid resonance conductor having an internal volume through which a particulate solid material flows, the rigid resonance conductor including a circular support and transducer supports coupled to the circular support, the transducer supports applying pressure to respective transducers against an exterior wall of the rigid resonance conductor;
- and
- an electronic circuit board including a maintenance indicator, a power indicator, a microprocessor, a radiofrequency transceiver, and the internal battery.
