Factors listed are directly usable to convert volume readings from displacement meters at various metering pressures into volumes at the standard base pressure and atmospheric pressure indicated above. For a 14.65 base pressure, use an additional multiplier of 1.006. PSIG Factor PSIG Factor PSIG Factor PSIG Factor PSIG Factor PSIG Factor In order to determine soil moisture content based on statistical correlation (w = 110.68ρ-0.347), correction factor, C was established through laboratory and field ERV given as 19.27.
For all species, correction factors were negative for most of the moisture content range, meaning that the meter readings were generally greater than the true moisture content. The 95-percent confidence intervals for true moisture content as . Hand-held moisture meters are frequently used by conservators and conservation architects for the non-destructive investigation of dampness problems in stone and mixed building structures, despite such meters being primarily developed and calibrated for wood. Following extensive use of hand-held moisture meters on historic stone monuments under field . Moisture content (MC) has an important effect on the performance of wood in service. In an attempt to rapidly and non-destructively acquire the MC of heat-treated wood, a radio frequency-type .
The amount of surface soil moisture (SSM) is a crucial ecohydrological natural resource that regulates important land surface processes. It affects critical land-atmospheric phenomena, including .
Moisture meter correction factors for high temperature dried softwood. Forintek Canada Corp. internal report. Pfaff, F. and P. Garrahan. 1984. Moisture content correction tables for resistancetype moisture meter (revised temperature corrections). Forintek Canada Corp., report SP511E, Ottawa. 21 26 – 24 22 20 180°F • 200°F 220°F . The weight of the grain is also a factor that will affect the moisture result. For many of the meters that were placed into service prior to January 1, 1998, the user must weigh the sample of grain prior to putting the sample in the grain moisture meter’s hopper. Some of these meters have a scale within theThe correction factors can be used with most resistance-type and the Wanger L-612 capacitance-type moisture meters in the range from 6 to 26 percent moisture content. Much of the hardwood lumber that is kiln-dried is destined for indoor utilization in .
example, moisture meter correction factors for untreated and ACQ treated plywood were provided by Boardman et al. [58] but did not include temperature compensation. Correction factors for OSB by Carll et al. [5] and Maref et al. [59] similarly were developed onlyat room temperature. The lack of temperature correction factors for moisture contentresults on air-dry basis should be multiplied by the moisture correction factor (MCF) to obtain the result on oven-dry basis. VII. Report Report moisture content (in %) with 1 decimal place. VIII. Reference ISO 11465. 1993. Soil Quality – Determination of dry matter and water content on a mass basis – Gravimetric method.

Different types of wood . Download Citation | Moisture meter correction factors for yellow poplar bark | Tree bark can be cut from logs in sheets, dried flat, and cut into pieces for use as an exterior siding material. For .Conductance-type (or resistance) meters measure moisture content in terms of the direct current con-ductance of the specimen. Dielectric-type meters ar e of two types. Those based principally on dielectric constant are . The correction factors are added to the readings for temperatures less than the calibration tem-
For professional woodworkers, contractors, farmers, restoration specialists and anyone else for whom monitoring the moisture content of what they’re working on is a factor, it is important to have an accurate, reliable moisture meter. But, how accurate is your moisture meter? Verifying that your moisture meter is in caSo the meter now shows a higher reading. For this reason a further correction factor is needed for a moisture meter to be used with grain undergoing drying in a heated-air dryer. This is why calibration must be done under the specified conditions. Once this correction factor is added, then a meter can be used even with grain undergoing drying.While pin and pinless moisture meters are a great way to measure moisture in wood and other building materials, it is important to know what factors can influence a moisture reading, and how. This way, you can take these influences into account so you can have the best information possible regarding the moisture content of your building materials.(2013). “Calibration of RF Moisture Meter,” BioResources 8(4), 5549-5560. 5549 Correction Factors for a Radio frequency-Type Moisture Meter for Heat-Treated Wood Tao Li, Jia-bin Cai, Lian-bai Gu, Tao Ding, and Ding-guo Zhou * Moisture content (MC) has an important effect on the performance of wood in service.
The key to success when using wood moisture meters lies in accuracy. Different technologies and features require careful selection and understanding of your moisture meter’s operation. Some meters, like our Orion pinless wood moisture meters, automatically adjust for wood temperature, while others might need correction tables.We continuously add correction factors to our moisture meters to allow accurate measurements for different wood species and newly introduced materials to give our customers up-to-date moisture meters. In the past years we have added corrections for bamboo, OSB, Advantech and other flooring products. .
