KLINGAGE Glass for Liquid Level Gauge (Water Level Gages:JIS B8211)
- Reflex glass
- Five 90°prismatic serations are cut into the liquid contact surface of tempered reflex glass to give a prism effect over the whole visual area.Incident light is passed through glass at the liquid phase and is reflected back to the observed as an interface between the dark liquid phase and the bright gaseous phase.
It turns when watching only over the liquid rank. It isn’t suitable for the watch of the phase boundary, the watch of the liquid color and so on.
- V-notched Color Glass（Bi-KCglass)
- LUKING Bi-KM and Bi-KC, developed by Nihon Klingage, are gage glasses which are V-notched and painted red. (Other colors available.) Such gage glasses enable observation at a distance from the gage because the color of the fluid is reflected through the liquid phase and red coloring on the side is reflected through the gaseous phase. V-notched color glasses are widely used for observation of colorless lilquids in transparent gages.
- Transparent Glass
- One sheet of flat tempered glass is mounted on each side of the liquid chamber and held between gage covers. The liquid level, interface level and liquid color can be observed by differential transmission of light emitted from the illuminator behind the gage.
Transparent liquid level gages are applicable to almost all liquids, especially for observation of interface between two liquids, observation of liquid color, and liquids and steam which require corrosion protection by shielding with mica or fluorocarbon resin.
