Volume measuring device
Determination of the bulk of a liter of grain and conversion to EEC bulk density for trade
- Bulk density for barley, oats, rye and wheat.
- Robust design (brass), 0.25 liters or 1.0 liters
- Simple and easy operation
- Exact measurements
- Good reproduction
The high-precision grain testers are used to measure the EEC bulk density (bulk per hectoliter, hectoliter weight) of barley, oats, rye and wheat. The bulk is determined with the aid of a balance. The ratio of bulk to volume results in the bulk density, which is corrected with the factors from the official tables for liter and quarter liter samples. A calibrated balance is required for determination in the trade, and is available as an accessory.
Insert the skimming knife, insert the plunger weight into the measuring cylinder, fit the forward cylinder (1.25 liters) and pour in the grain sample. Pull out the skimming knife quickly. The plunger weight and the grain fall into the measuring cylinder (1.0 liter). Cut the volume exactly using the skimming knife. Pour out excess grain, remove the forward cylinder and weigh the contents on a calibrated precision balance. The bulk density (kg/hl) of the different grain types is then determined on the basis of the provided correction table.
