Four-parameter detection system for grouting and water-pressing is introduced.Main framework of the system is designed and its hardware and software structure.Four parameters of pressure

flow

water cement ratio and ground displacement is dynamically measured by this instrument using sensor technology

electron technology and PC technology.Experimental results shows that the system has the characteristics of good stability

high precision and sensitivity

quick response and so on

and it can work normally in harsh environment such as high temperature

humid and dusty.
