THE YPL Level gauges are used for measuring the level in the vessel. These can be used for maximum pressure of Upto150kg/cm² and a Maximum temperature of 400⁰C .constructional features include 2.5 Meter single piece construction with multiple glasses between process Connection. A pair of auto shut off ball check valves in material of Construction carbon steel or stainless steel and polypropylene as optional.
The principal of reflex level gauges is based on the difference in the refractive Indicates of liquid & vapor. The liquid column is contained within the recess Of liquid chamber behind the sight glass which is clamped to the gauge body. The Sight glass has prismatic right angled grooves on the side facing the liquid And vapor space light raise entering from right outside the gauge are either Absorbed or reflected depending upon whether they enter the liquid or vapor Space. When the ray of light encounters the surface of one of the grooves in vapor Space, it is reflected to the opposite space appears as silvery white. When the light Ray encounters the surface of grooves in the liquid space, it is totally absorbed Thereby the liquid behind the glass appear black.
Max temperature: 400⁰C
