Abstract

In application of the differential pressure water-level gauge for boiler drum

problems such as big deviation and unaccuracy are commonly existed.Through analysis of the pressure-taking device and the compensated computation parameters

the sampling tube and sampling facility of the measuring system have been retrofitted

and the compensated computation parameters being optimized.After retrofitting and optimization

the stability and measuring accuracy of the differential pressure water-level gauge for boiler drum have been effectively enhanced.
