A Novel LabVIEW-Based Automatic System for Deep-Water Hydrologic Sampling

Article Preview

Abstract:

A novel LabVIEW based system is designed to automatically sample hydrological samples in deep rivers. This paper is intended to describe the principles of the system design, the hardware component architecture and software design for the sampling operations. The designed system is capable of dynamically measuring the depth of water using a pressure sensor, as well as automatically taking hydrology samples by means of measuring cross-section 6 point method. The sampling operation tests showed the designed system has higher degree of automation, higher measurement precision, higher reliability and practicability.
