quartz glass tubular level gauges

quartz tubular level gauges(tubular level gauge; glass level meter; tubular level indicator; liquid level gauge) Selective type: bi-color (green and red color)single color (natural color)ordinary glass tubular level gaugequartz glass tubular level gaugewith back clamp (1.LED: power 24VDC;2.fluorescent clamp: 220VAC)steam tracingelectric heatinggenaral description: GZS type quartz glass tubular liquid level gauge GZS type quartz glass tube liquid level gauge is of local display. The features of mechanics, mechanical, electric and optics of quartz glass tube are superior to ordinary glass tube. Furthermore, it is superior to ordinary glass tube liquid level gauge because of the action of refraction and reflection, it has bicolor characteristic. And therefore it can be applied to measure fluid level of various kinds of industrial equipments such as pot, tower, tank and box. And particularly apply to measure the high temperature, high temperature difference, high pressure and acid fluid level. And because of the double color indicating action, it can specially affect the high temperature, normal temperature boiler liquid level double color indicating directly. Our quartz glass tube liquid level gauges all adopt SiO2 quartz glass, purity is 99.99%, transform temperature is 1075, compression resisting is 1000MPa(10,000kgf/cm2), factor of expansion is 5.5×10-7. And quartz glass tube, according to the standard of JC225-81, after special dealing, make to transparent quartz glass tube as the meter measuring body. And after the delicate design of meter structure, the gauge has the characteristics of clear display, high ability of resist compression, convenience to install, protect and maintain. 1, GZS-A type double color quartz glass tube liquid level gauge 1)measure ranges:300 2200mm 2)working temperature: -20 450 3) nominal pressure: PN0 6.4MPa 4)quartz tube test pressure:≤13MPa 5)meter material: high quality carbon steel or 1Cr18Ni9Ti 6)green for liquid and red for air 2,GZS-B type black and white quartz glass tube liquid level gauge 1)measure ranges:300 2200mm 2)working temperature:-20 450 3) nominal pressure: PN0 6.4MPa 4)quartz tube test pressure:≤13MPa 5)meter material: high quality carbon steel or 1Cr18Ni9Ti 6)transmit color: nature color 3,GZS-C type general glass tube liquid level gauge 1)measure ranges:300 2000mm 2)working temperature: ≤200 3) nominal pressure: PN0 6.4MPa 4)meter material: high quality carbon steel or 1Cr18Ni9Ti 5)flange standard:DN15,20,25 or others 4.GZS-D electric thermal bi-color level gauges 1flange to flange: 300 2200mm 2) working temperature: ≤200 3) Nominal pressure: PN0 6.4MPa 4) Meter material: high quality carbon steel or 1Cr18Ni9Ti 5) flange standard and specifications: supplied by customer 6) electric thermal: thermal belt 7) electric thermal power: 220VAC or 24VAC 8) electric thermal temperature: 50 150 5.GZS-G high temperature and high pressure level gauge 1) flange center to center: 300 1000mm 2) working temperature: ≤450 3) nominal pressure: ≤10MPa 4) meter material: high quality carbon steel or 1Cr18Ni9Ti 6,GZS-H type double color quartz glass tube liquid level gauge with back light 1)measure ranges:300 2000mm 2)working temperature: -20 450 3) nominal pressure: PN0 6.4MPa 4)meter material: high quality carbon steel or 1Cr18Ni9Ti 5)back light: a,light Emitting Diode: electric power supply is 24VDC. b, fluorescent light tube:electric power supply is 220VAC 7,GZS-Z type steam thermal double color quartz glass tube liquid level gauge 1)measure ranges:300 2000mm 2)working temperature: -20 450 3)nominal pressure: PN0 6.4MPa 4)meter material: high quality carbon steel or 1Cr18Ni9Ti 5)steam thermal connecting tube: flange DN15 or flange 1/2×1.5
