Introduction
Water level is the basic element of hydrological monitoring and an important basis for the construction of water conservancy projects, flood control and drought relief, and water resources management. now
The high-quality development of modern water conservancy puts forward higher requirements for the automation, intelligence and accuracy of water level measuring instruments.
Standardization of instruments is the basic work to promote the development, production, inspection and use of water level measuring instruments.
GB/T 11828 "Water Level Measuring Instrument" is intended to be composed of four 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 for float-type water level gauge products.
--- Part 2.Pressure water level gauge. The purpose is to specify the technical requirements, inspection rules and methods for pressure water level gauge products.
--- Part 3.Acoustic water level gauge. The purpose is to specify technical requirements, inspection rules and methods for acoustic water level gauge products.
--- Part 4.Electronic water gauge. The purpose is to specify the technical requirements, inspection rules and methods of electronic water gauge products.
This document is Part 2 of GB/T 11828.

3 Terms and Definitions
The terms and definitions defined in GB/T 50095 and the following apply to this document.
3.1
pressure-type stage gauge
An instrument that uses a pressure sensor to directly or indirectly sense the hydrostatic pressure of a water body and convert it into a water level.
3.1.1
Submersiblepressure-typestagegauge
The pressure sensor is placed at the underwater measuring point to directly sense the hydrostatic pressure and convert it into an instrument of water level.
3.1.2
bubble-typestagegauge
The hydrostatic pressure of the underwater measuring point is converted into gas pressure by the blowing pressure device, and the pressure is led above the water surface.
An instrument that induces gas pressure in a device and converts it into a water level.
3.2
time drift timedrift
Under reference working conditions, when the measured and environmental conditions are kept constant, the change in the output of the instrument within a specified time.
