On-line moisture measurement of rocks, using microwave techniques
On-line measurement of the moisture content of process streams in a mineral processing plant is vital for their efficient operation. Although many industrial moisture meters are available, most of these were designed to determine the moisture content of low density, fine grained, uniformly surfaced …

Phase-based soil moisture sensing using radars and passive backscatter tags
Soil moisture sensing is important to optimize water usage in agriculture and fire prevention. In agriculture, it enables smart irrigation systems to use water efficiently, reduce wastage, and enhance crop yields. For fire prevention, accurate soil moisture data improves estimates of fuel moisture …

Application of thermocouple psychrometers to field measurements of soil moisture potential.
… thermocouple psychrometer has made possible the measurement of soil moisture potentials to values as low as -80 bars. The applicability of this type of psychrometer to "in situ" measurements of moisture potential at a Sonoran desert field site is investigated. An evaluation is made of the effect …

Organic emissions during oven drying of wood
When oven drying Douglas fir to determine moisture content, volatile organics evolving from the wood cause error in the moisture measurement. An apparatus was constructed to measure the carbon contained in the evolved organics and to measure the chemical energy content of the organics which evolved …

Accuracy of hay moisture sensing systems for round alfalfa bales
Moisture measurement is critical when baling alfalfa into round bales for feed. If alfalfa is too wet or too dry, it can greatly diminish the alfalfa crop’s feed quality and cause economic loss to producers. Therefore, monitoring of alfalfa moisture content while baling is critical for producers to …
