As its name implies, the direct vision-type liquid level gauge is a device that allows operators to confirm the remaining liquid level in an industrial plant-related tank, etc., directly with their own eyes.

For around half a century we have been manufacturing water / liquid level gauges under the OBK brand, Our water level gauge is used not only for tanks but also for power generation-use boilers, and supports both low pressure and high pressure (21MPa) applications.

We have an excellent delivery record for both domestic and overseas sales of this product (domestic market share: approx. 50%).

For tank-use, we supply tubular liquid level gauges in large numbers. We also utilize an extensive lineup of materials including SUS, PVC and lining for valves in order to ensure that it is well-matched to the customer's using environment.

For power generation boiler-use, we prepare water level gauges enough to resist high pressure (~21MPa).
