The system includes automatic water supply and flow regulation, water level control by tail-gate, automatic sand feeding control, and integrated and coordinated control with multi-object and multi-parameter. The automation of water supply and sand feeding is accomplished and the test efficiency and precision is improved. %U http://ckyyb.crsri.cn/EN/10.3969/j.issn.1001-5485.2012.07.020
