Jerguso杰格森 Series 300L Low Pressure Armored Level Gages
Standard costructioincludes a solid one-piece chamber machined from bar, bar stock covers,empered glass, steel bolts anduts. Series 300L gages are available with carbosteel or stainless steel chambers. The Series 300Leplacshe old Series 12 whicheplacedhe old Series 5 gages.
One ofhe simplestechniques for indicating liquid level is by means of a directeading device with whichhe level cabe seevisually. A commomethod of providing such visual indicatiois by installing directeading gages ithe vessel itself. These directeading gages are placed adifferenlocations or poiso indicatehe liquid height. More often, separately moued gage glasses are usedo provide a cotinuous indicatioof level over a certaivertical distance othe vessel.
Theransparenglass gage cosists of a one piece ceral chamber with cover plates oeach sidehaholdhewo glass windows. The chamber and cover plates have machinedecesseshakeep allhe parts aligned and prevehe gaskets and cushions from shifting. Whethe level of caustic or acidic fluids is indicated,he inside surfaces of both glasses are lined with a protective coating ofransparenmica. After prologed exposureo highemperature, chemically-treated water,he mica will become opaque. This discoloratioindicateshathe mica has failed and water isow idireccotacwithhe glass. Whethis happens,he glass should be changed, before ifails.
