<P>PROBLEM TO BE SOLVED: To provide a water gage bearing conductivity meter capable of preventing its water gage and conductivity meter which are immersed in the same tank, from interfering with each other. Ž<P>SOLUTION: The water gage bearing conductivity meter is configured such that a first electrode unit 20 for measuring a conductivity and one or at least two second electrode units 30 for detecting a water level are immersed in the water tank 1. The first electrode unit 20 includes: a first transmitting electrode X<SB>1</SB>which is connected with the only common-use AC transmitting circuit 22 and transmits first signal current I<SB>1</SB>; and a first receiving electrode Y<SB>1</SB>which is connected with a measuring circuit for measuring the conductivity by acquiring the first signal current I<SB>1</SB>from the first transmitting electrode X<SB>1</SB>through an electrode gap. The second electrode unit 30 includes a second receiving electrode Y<SB>2</SB>which is connected with a detecting circuit for receiving second signal current I<SB>1</SB>from the first transmitting electrode X<SB>1</SB>and detecting its presence or absence.
