Probably not. Soil moisture meters need to be calibrated to even read soil water - the amount of non-available water in any soil changes with clay content (and other things) .
See the soil water section of www.bettersoils.com.au for basic info on water in soil.
Dr. Massimi, soil moisture meter can only measure the volumetric water content in the sample.
Answer will be straight no , but most of the soil moisture meters need to be calibrated against volumetric soil moisture content ..

I have a gravimetric electronic sensor which is self calibrated and ready to use. It calculate soil moisture percent directly on dry weight basis at a depth of no lower than 10 cm.

The sensor I have is gravimetric self tested and calibrated. It's ready to use in field to measure soil moisture content percentage on dry weight basis.

Water in garms/ dry soil in grams
The only calibration I made is to multiply the record with soil bulk density measured to find a volumetric soil moisture content record.
I just used it after sample full saturation and 48 hours full drain to get moisture content at field capacity point.
