Page 3: Operating Principles
Page. 3 / 12 1. Overview HTMF-MF is a multipoint thermal dispersion–type gas flow meter. It enables measuring of gas flow even at an installation location where flow distribution is not even based on multipoint gas flow measurements. It is designed to have a microprocessor in the flow transmitter for high accuracy and a self-diagnosis function. -
