  • Introduction
  • Specifications
NWP-LK series flow totalizer controller is used to measure and totalizer flow of all kinds of liquid, vapor, natural gas and ordinary gas. It uses look-up table method and can do high accuracy totalizer control for superheated steam, saturated steam, etc. automatically. It can calculate the flow coefficient K according to parameters which make the parameter setting more convenient and more accurate.
