Social infrastructure(water level meters)

JTEKT has been producing water level meters since 1986 using the technology cultivated from pressure sensor, auto parts and machine tools development and manufacturing.

Our water level meters sense water pressure with diffused semiconductor device for measurement of depth of water and it has been called "Throw-in type" or "Immersion type".

Our water level meter is superior for long-term stability and replacement of parts is not required for easy maintainance for longer period of time.
Therefore, they are contributing maintainance-free and longer life in thousands of locations across the country such as water supply, sewage plant, wells, rivers and dams.
It has an amplifier and an arrester built-in, but has a compact design and thin body,
and also contributes to reduction in setting work according to its original high-strength cable which doesn't require the use of a chain.(When a bracket isn't combined.)

Throw-in type water level meters
