Hebei Xukang Meter Manufacture produce various sight glass. we have Transparent/reflex Glass tube Water Level Gauge,magnetic float Level Indicator-Water Level Meter,mica sheet double color level gauge,sight glass flow indicatorLevel indicators model selection, features and application1. Transparent glass level gauge: two side glasses, clear to see liquid level inside. good to dark liquid, may work at high pressure <16MPa, temperature <250ºC, <500ºC;2. Reflex glass level indicator: one side glass, pressure <6MPa,temperature <250ºC, <500ºC;3. Glass tubular level gauge: can working at high temperature <600ºC. working pressure: <6.3MPa4. Magnetic level gauge: temperarure <450ºC; pressure <16MPa underground tank top mounted or side mounted; can assemble level switches and level transmitter to realize remote control and remote level reading.Not the type you are searching for?Contact us for more catalog, you will find here really a big shop, where can supply you all the industrial products from the only one supplier.We produce and trade in various level gauges ------Bi-color Sight glass level gaugesTransparent Flat Glass Level Gauge/See-Thru Liquid Level GaugeReflex Flat Glass Level GaugeDefrost typeWeld Pad Flat Glass Level Gauge(level meter,level indicator, water level gauge, liquid level gauge, sight glass, water level meter, level controller,level switch, level sensor,tank level gauge,glass level gauge, glass level indicator)Visual level indicator tube bypassTransparent Tubular Level GaugeWith drain valvesAre you worrying our products quality?Our products was bought by world user for hundreds of pcs with many orders of month.Material:Carbon steel; 1Cr18Ti9Ti; AISI316 corrosive fluid; Other material on order.Choices:High temperature; High pressure; Defrost level Gauge; Reflex Level Indicator; Transparent; Boiler flat type; Single color or bi-color; Sight glass Back light type and electric thermal type glass level gauge.General introductionTBS glass plate liquid level gauges are level measuring instrument. Upper and lower needle switches and indicating equipments are their main components. Fluid flows via switch into the indicating equipment, then the liquid level will display clearly viewed through the range of effective light transmission. And on that basis, we have developed double color glass sheet liquid level gauges, defrost glass sheet liquid level gauges and steam thermal glass sheet liquid level meters to adapt to different places and different conditions.About sight glass plates's glass quality, only borosilicate glass is used. The connection to the process is generally made with valve heads with single or double isolation. Drain valves enable the sight glass indicator to be emptied and are fitted to the lower flange face. If necessary, a vent valve can be fitted at the top.The Reflex Liquid Level Gauge is used to see the level of the liquid in a vessel or tank. The gauges are used as a single unit or stacked up in multiple sections to view a desired height of liquid in a vessel or tank. Standard units are furnished with 1/2" or 3/4" NPT female-end connections. The Reflex can also be furnished with other connections (socket weld, flanged, sanitary, or as specified) as well as with various types of valves upon request. Reflex liquid level gauges offer low initial cost and, if there is no reason to observe the media, easy level reading.Model selection: 1, TBS-A type transparent liquid level gauges1) Measure range: 500~1700mm2) Working temperature: ≤ 2503) Working pressure: ≤ 4MPa4) Meter material: Qualitative carbon steel or 1Cr18Ni9Ti5) Transmit color: Nature color2, TBS-B type double color glass sheet liquid level gauges1) Measure range: 330~440mm2) Working temperature: ≤ 2503) Working pressure: ≤ 4MPa4) Meter material: QualitativeCarbon steel or 1Cr18Ni9Ti5) Transmit color: Nature color3, TBS-C type defrost glass sheet liquid level gauges1) Measure ranges: 300~2000mm2) Work temperature: -40~603) Working pressure: ≤ 4MPa4) Needle switch closeAutomatically pressure: ≥ 0.2MPa5) Defrost pin height: 100mm, 150mm, 200mm, the lower the temperature the higher the pin.6) Flange material: Qualitative carbon steel or 1Cr18Ni9Ti4, TBS-F type reflective glass sheet liquid level gauges1) Measure ranges: 300~2000mm2) Work temperature: 0~2503) Working pressure: ≤ 4MPa4) Needle switch close automatically pressure: ≥ 0.2MPa5) steam insulating sheath pressure: ≤ 0.6MPa6) flange material: Qualitative carbon steel or 1Cr18Ni9Ti5, TBS-S weld pad sight glass sheet liquid level gauge1) Light transmission size: 18× 304mm2) Working pressure: ≤ 1.0Mpa3) Working temperature: ≤ 2504) Jointing size: 80× 366mm5) meter face material: Qualitative carbon steel or 1Cr18Ni9TiModelNameProcess ConditionRangePicturesTBS-ATransparent level gauge0~250ºC13.0MPa200~2200mmOr longer TBS-FReflex level gauge0~250ºC13.0MPa200~2200mmOr longer TBS-HTransparent high pressure high temp. level gauge380ºC16.0MPa200~2200mmOr longer TBS-25Glass sheet level gaugewith Plug-cock0~250ºC2.5MPa200~2200mm W40H-40Glass Level gauge with 1/4 quick open/close valve0~250ºC4.0MPa250~440mm300~440mm TBS-CTransparent level gauge defrost type-160~60ºC4.0MPa300~2000mm TBS-B-Hbi-color glass flat level indicator with lighting0~250ºC2.5MPa250~440mm TBS-ISteam insulation typeWith steamHeating jacket250~2200mm TBS-Sweld type sight glass level gauge0~250ºC10.0MPa300~1400mm
