Direct View Liquid Level Gauges

As per its name, the direct view liquid level gauge is a device that allows the level of liquid remaining in a tank to be checked visually. It is suitable for use in industrial plants.

For around half a century, Sawada Seisakusyo has been manufacturing not only such tanks, but also water level gauges under the OBK brand capable of handling electric power generation boilers from low to high pressure (up to 21 MPa).

They are experts in their field with many happy customers in Japan and abroad. In Japan, they hold approximately 50 percent of the market.

For tanks, their most popular type of liquid level gauges use round glass tubes, with valves available in a wide lineup suited to any operating environment, ranging from stainless steel and vinyl chloride to lined models.

For electric power generation boilers, Sawada Seisakusyo manufactures water level gauges capable of high-pressure use.
