✔︎ In case where the glass tube is used, consecutive viewing of liquid level can be done up to 1800mm by a piece of glass tube. When the longer viewing than 1800mm is required, visible length can be extended with an additional glass tube joined by an intermediate coupling.

✔︎ In case of liquid corrosive to the glass tube, resinous tube such as acrylic tube is applicable instead so that it is applicable widely usable for various kinds of applications.

✔︎ With the glass tube lined in red at its back, level viewing becomes easy because liquid part of the glass tube is occupied fully in red by convex effect of tube.

Tubular type level gauge is the most simplified gauge in the level gauges. Consisting of the gauge valve and gauge tube (glass tube or resinous tube), a protection is mounted over the gauge tube.
