Sawada ET-20 type Level gauge – See-through Type Level Gauge | Kouei Japan Trading

Made in Japan
Manufacturer: Sawada Manufacturing Co., Ltd
Model: ET-20 type

This level gauge has a structure in which reinforced gauge glasses are placed on the front and back of the gauge body, sandwiched between covers and tightened with bolts so that the liquid level can be seen through the gauge glasses.

Features

connectioin type: Flange・Screw・Socket
Maximum working pressure: 4.0 MPa
Maximum operating temperature: 350℃
Material: SUS304/316/316L
Installation length: 285-3000mm

Visibility

The surface of the liquid, the interface between the two liquids that do not mix, and the color of the liquid can be visualized through the two gauge glasses.
If it is difficult to see the liquid level in a clear liquid or in a dark place, installing a lighting device behind the level gauge will make the liquid level easier to see.
