Functional Description Sight Glass Level Gauges Reflex glass type acc. to DIN 7081 Incident light is reflected at the reflex grooves of the sight glass plate covered by gas and is broken into the liquid in the part covered by medium. The liquid level is visible as a dark bar, the gaseous space as a silvery bar. Sight direction Sight direction Gaseous phase Liquid phase Transparent glass type acc. to DIN 7081 Incident light is reflected at the reflex grooves of the sight glass plate covered by gas and is broken into the liquid in the part covered by medium. The liquid level is visible as a dark bar, the gaseous space as a silvery bar. Sight direction acc. to DIN 7081 Refraction type with mica sheets The incident light of a lamp is guided through the two mica sheet packages in an angle and passes the medium between them. In gaseous phase the light is guided straight forward and passes both mica packets, in liquid the light is refracted away. The liquid level is visible as a black bar and the gas as a bright bar.

Borosilicate glass is standard quality. For A duct for the medium (or heating agent) is machined into the conditions above the natural mineral mica is used. The process gauge body as well as the support surfaces for the gaskets connection normally is equipped with gauge valves. Drain valves and glasses or micas. Glass plates and/or micas are mounted are used for draining the gauge and are generally mounted on with gasket and cushion and are fixed with the cover plate or the lower end of the gauge body. In Special cases a vent valve pressure frames and bolts. The glass plates used for sight can be installed on the upper end. glass level gauges correspond to DIN 7081 and are suitable for temperatures up to 243 °C (280 °C when protected with mica) for steam, up to 300 °C for other Iiquids, and in special Gauge body Glass Contains the liquid duct, the level corresponds with the level Glass plates according to DIN 7081, made of Borosilicate- in the vessel.

All gauge valves are equipped with a ball the level gauge. The actuation can be done by a lever (120°) check as a safety device.. Functional principle ball check ball check at leakage situation during putting situation in normal into operation operation The ball check is a safety device which is used in all gauge causing flow of liquid, the ball is driven to the seat by the valves. It’s task is to avoid heavy leakage after breaking of a liquid (L1p > 0,5 bar). This closes the valve and stops heavy glass or mica window or leakages due to other reasons. The leakage. ball is located below the seat.
