Protem introduces a new measurement, Ampere per cubic meters (A/m³), for concrete consistency established.

PROTEM designed an instrument for its automation systems to measure the actual power consumed by the concrete mixer and then relates this to a new unit of measurement arbitrarily named “A/m³.” With this innovation, the operator gains a much better understanding of the consistency (slump) of the mixture inside the mixer, as previously, a simple analog ammeter was primarily used for this purpose.
