Abstract

A moisture measurement device in a concrete manufacturing system, where a concrete mixer mixes gravel, cement, additives and water, comprises a control means (8, 30) for selectively opening a measurement door (51) in a measurement opening (52) in a gravel bin (1). The moisture contents in a gravel sample (55), which is fed from the measurement opening to a measurement container (41), is calculated in the control means by resistance measurement in the gravel sample in the measurement container. The water supply to the concrete mixer is thereafter adjusted in accordance with the measured moisture contents.
