UGDS series bi-colored quartz glass tube level meter is directly reading meter.can read level height through quartz glass tube.by refleting and refraction light ,the liquid in the glass tube is red ,the gas is green.steel balls in the up and down valves can close the glass tube tightly.

features:

1、  Can resist high temp,high pressure.
2、Dolorful showing,red liquid ,green gas.
3、Can indicate position in 360°.
4、Far distance alarming to prevent explode.

parameter：

1、 specification(central distance) L=300～2000mm
2、  length and width: L1×h=（160～1860）×20
3、  pressure≤6.4Mpa
4、  medium temp.: -50～+520℃
5、 steam pressure: ≤0.6Mpa
6、 steam connect:M20X1(outside)
7、 steel ball self-closing pressure: ≥0.3Mpa 
8、 connecting flange: JB/T81-94、JB/T82.2-94
9、 flange pressure: PN2.5  PN4.0  PN6.4
10、flange diameter:DN20(side)

theory:

   Made up of quartz tube,connecting flange etc.by natural light ,clearly observe the level height
