Asphalt Calibration System Stansteel Asphalt Plant Products
liquid asphalt can be calibrated and weighed by a separate holding vessel that is supported on multiple load cells and calibrated with a known weight. In order to ensure the accuracy of the liquid asphalt metering system, it is mandatory that the hot mix producer runs a calibration check on their asphalt metering on a periodic basis. with the stansteel automatic a.c. calibration system using the proper piping and valving, the a.c. can be diverted from the run line on the plant during calibration, test weights are added to the belt scale to simulate the desired production rate. asphalt is diverted or pumped into a tank or distributor truck. readings are taken on the flow meter or revolution counter and totalizer counter. readings are also taken on the dials and meters, and a tachometer reading may becalibration tanks are used to calibrate the liquid asphalt metering system of a drum mix asphalt plant. calibration tanks save considerable time and money, and are available in vertical or horizontal styles. efficiency is a concern. using a calibration tank is far more efficient than using a distributor truck, a common practice in the
