    College of Quality and Technical Supervision, Hebei University, Baoding, 071000, China

 Abstract

The glass tube rotameter is usually used only for site instructions, without remote transmission. In this paper, the inductance sensor detects the float's displacement, with the coil around the inner tube, core installed on the float. As a result, the displacement of the float caused by the flow can reflect the inductor changes.

 1. Introduction

Electrochemical processes usually occur under condition of electric neutrality of a system as whole and its macroscopic parts separately. A set of electrochemical reactions may be quite complicated, but the deviations from neutrality usually have scale determined by Debye length only, i.e. known types of chemical processes cannot result in appearance of macroscopic electric charge and electric currents.
