ELECTROMAGNETIC INDUCTION TYPE ELECTRICAL CONDUCTIVITY METER

摘要

PROBLEM TO BE SOLVED: To provide a liquid non-contact type electromagnetic induction type electric conductivity meter capable of measuring accurate electric conductivity in all electromagnetic induction type electric conductivity meters, even when the plurality of electromagnetic induction type electric conductivity meters are installed for the liquid to be measured.;SOLUTION: An electromagnetic induction type electric conductivity meter 10 having a detection unit 14 for detecting the electric conductivity of a liquid to be measured and outputting a signal corresponding to the electric conductivity detected by the detection unit 14, includes: a station number address acquiring unit 11 for acquiring a station number address that indicates what number of the electrical conductivity meter is the electromagnetic induction type electric conductivity meter 10; a frequency determining unit 12 for determining the frequency corresponding to the station number address acquired by the station number address acquiring unit 11 as the frequency used by the electromagnetic induction type electric conductivity meter 10 itself; and a control unit 13 for instructing the detection unit 14 to apply a signal of the frequency determined by the frequency determination unit 12.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
