6.1 How moisture is deﬁned

The device measures and shows a material’s moisture content. The moisture content readings it displays are calculated in relation to the material’s overall mass:

Mn: Mass of the sample with average moisture content

Mt: Mass of the sample with zero moisture content

%WG: Moisture content (in accordance with EN ISO 18134-2)

Page 26

humimeter BMA-2 Operating Manual

Page 26

6.2 Deﬁnition of wood chips types (Norm EN ISO 17225-1)

The given numbers, in accordance with EN ISO 17225-1, refer to the particle sizes that ﬁt through the round screen openings.

• P16 at least 75% of the mass between 3.15 and 16mm

• P31 at least 75% of the mass between 8 and 31.5mm

• P45 at least 75% of the mass between 8 and 45mm

• P63 at least 75% of the mass between 8 and 63mm

6.3 Selection of calibration curve for wood chips

The calibration curves for wood chips depend on the wood type (hardwood, softwood), the size of the chips (size classes according to norm EN ISO 17225-1) as well as on the content of ﬁne fraction.

If you are not sure which calibration curve is the best suited for your material, it is recommended to carry out a reference measurement by kiln-drying (according to EN ISO 18134-2).

Schaller GmbH will be happy to advise you on the selection of the right calibration curve. Please send a picture of your wood chips, placing a measuring tape to the material, to [email protected]. You will receive a recommendation from us immediately.

6.3.1 Wood chips

For wood chips with ﬁne fraction, consisting of at least one third hardwood. The ﬁne fraction mainly derives from barks, small branches and bushes. For wood chips sizes from P31 to P45. See example pictures 40 and 41.

If your wood chips contain few ﬁne fraction or no ﬁne fraction or if the wood chips contain a higher proportion of softwood, use one of the following calibration curves.

6.3.2 Coarse wood chips

For coarse wood chips without ﬁne fraction, consisting of at least one third hardwood. This curve is predominantly suited for measuring wood chips deriving from logs and full trees. For wood chips sizes from P45 to P63. See example pictures 42 und 43.

If your wood chips contain a higher proportion of softwood, use one of the following calibration curves.

Page 27

6.3.3 Softwood chips

For wood chips with ﬁne fraction, mainly (more than two thirds) consisting of softwood (spruce, ﬁr, pine, larch). The ﬁne fraction mainly derives from barks, small branches and bushes. For softwood chips sizes from P16 to P45. See example pictures

44 and 45.

If your wood chips contain few ﬁne fraction or no ﬁne fraction, use one of the following calibration curves.

6.3.4 Softwood coarse chips

For coarse wood chips without ﬁne fraction, mainly (more than two thirds) consisting of softwood (spruce, ﬁr, pine, larch) of 70% and more. This curve is predominantly suited for measuring wood chips deriving from logs and full trees as well as sawmill residues. For wood chips sizes from P45 to P63. See example pictures 46 and 47.

6.3.5 Fine wood chips

For ﬁne wood chips with a high proportion of ﬁne fraction, consisting of at least one third hardwood. The ﬁne fraction mainly derives from barks, small branches and bushes. For wood chips size P16. See example picture 48 and 49.

For wood chips purely from ash trees, wood chips sizes from P31 to P45, also choose this calibration curve.

6.4 Notes for the measurement of wood shavings

The weight of the measured shavings must be at least 380 g. Otherwise the shavings in the chamber have to be compressed to 380 g.

6.5 Notes for bulk density and dry weight (atro)/m³

For determining the bulk density according to norm EN 14961 a round bucket is used.

As the humimeter BMA-2 device uses a rectangular measuring chamber, a compensation factor is stored in the device. This compensation factor has been optimised for wood chips and therefore can differ when measuring other material types. The bulk density of biomass material during transport can change considerably (compacting), when measuring the volume a material cone has to be considered.

An eventual discrepancy of the bulk density directly inﬂuences the displayed dry weight (atro)/m³.

6.6 Notes for comparative measurement with oven-drying method

The device uses a much higher sample quantity than the drying oven (12-fold to 20-fold quantity of kiln-drying method). Furthermore, to determine a more accurate average moisture value in case of inhomogeneous material, there can be effected several measurements within a short time.

Considering a sampling error due to the considerably smaller sample quantity as well as the content of volatile matters, resin etc. (that are not water), the kiln-drying method will practically reach an accuracy of approx. +/- 3 %. Therefore, if the measuring values of these two very different methods of determining the water content are compared, differences of +/- 3 % can be considered to be normal.

In the standard EN ISO 18134-2 is declared that the drying oven method provides no absolute values, but only comparable values.

terial being measured is too low or high. I.e. the material’s temperature is lower than 0 °C or higher than +50 °C.

The temperature of the material being measured has to be between 0 °C and +50 °C.

Frozen material or material mixed with snow Accuracy decreases signiﬁcantly

The material must not be frozen or mixed with snow.

Wrong product type Check whether you have

selected the right product type (product) before taking a reading (see "5.2

Taking a measurement").

Mouldy or rain wet material Accuracy decreases signiﬁcantly

Only measure dry, not mouldy material.

Insufﬁent material in the measuring chamber

Ensure that the measuring chamber is completely ﬁlled with material; there must not be less nor more material in it.

Wrong ﬁlling procedure The measuring cham-

ber has to stand on the ground when ﬁlling it. Always use the included bucket for the ﬁlling.

Wrong ﬁlling direction Always ﬁll the measuring

chamber from the side with the metal plate.

LED ﬂashing red Drawer not closed correctly Close the drawer comple-

tely. Press to conﬁrm the error message.

12. Troubleshooting

12.1 Cleaning the contacts of the measuring chamber

To do so: The automatic calibration is not successful and the exclamation mark on the

display does not go away. The contacts of the measuring chamber are polluted.

1. Lightly sand the contacts (ﬁgure 70) with a ﬁne sandpaper (K400). The contacts are made of stainless steel.

2. Clean the contacts with a cloth and cleaning alcohol.

If this measure does not remedy the fault, please contact Schaller GmbH.
