3 Terms and definitions

The terms and definitions defined in GB/T 19677-2005 and GB/T 50095 apply to this document. 4 Product working principle, classification, composition and specifications 4.1 Working principle The vertical position of the float changes with the water surface, and the water level wheel is rotated by the suspension cable connected to the float, and the change of the measured water level is converted into The angular displacement of the water level wheel is measured by a scribe line recording device with a timing function, or a given digital signal is output by the encoder. 4.2 Classification 4.2.1 According to the water level coding method. a) Incremental type. according to the resolution requirement, a signal is sent every time the water level value is increased or decreased; b) Full-size. Converts the water level value into a digital quantity with a uniquely determined coded output for each division value within the range. 4.2.2 Simulated scribing method. Record the water level change process line by scribing. 4.2.3 According to the coding principle.
