Introduction
Water level is a basic element of hydrological monitoring and an important basis for carrying out water conservancy project construction, flood control and drought relief, water resources management and other work.
The high-quality development of water conservancy in the modern era has put forward higher requirements for the automation, intelligence and accuracy of water level measuring instruments.
Instrument standardization is the basic work to promote the level of research, production, inspection and use of water level measuring instruments.
GB/T 11828 "Water Level Measuring Instruments" is planned to consist of six parts according to the working principle of the instrument.
--- Part 1.Float type water level gauge. The purpose is to specify the technical requirements, inspection rules and methods of float type water level gauge products.
--- Part 2.Pressure water level gauge. The purpose is to specify the technical requirements, inspection rules and methods of pressure water level gauge products.
--- Part 3.Groundwater level meter. The purpose is to specify the product technical requirements and inspection rules for water level meters used to monitor groundwater levels
and methods.
--- Part 4.Ultrasonic water level meter. The purpose is to specify the technical requirements, inspection rules and methods of ultrasonic water level meter products.
--- Part 5.Electronic water gauge. The purpose is to specify the technical requirements, inspection rules and methods of electronic water gauge products.
--- Part 6.Remote water level gauge. The purpose is to specify the technical requirements, inspection rules and methods of remote water level gauge products.
