Level gauges type 708 are used to indicate the level of liquid in pressure vessels with a working pressure up to 16 bar. They can be also applied to boilers with working temperature up to 200 °C.
Depending on the location of handles, level gauges' heads are assembled in right or left versions.
If the order does not specify the type of version, level gauge heads are assembled in right version.
This level gauges are produced by Polish producers and are available in following versions:
- 708 - standard version
- 708CrNi - stainless steel version
- 708Z; 708ZCrNi - version with protection against flooding in case of breakage of the level gauges glass tube
Head mass - 5,3kg
In level gauges 708Z i 708ZCrNi (version with protection against flooding in the form of a ball) in the case of breakage of glass balls cut-off the flow of medium.
Flanges are drilled at PN 40 as for DN20 and executed with sealing surfaces type E with spline according to PN EN 1092-1.
Level gauges can be assembled in right or left versions (depends of handle's place); as a standard are assembled in right version.
Level indicators type 708 can be supplied with tube or without tube. We can also supply additional tubes. Glass tubes to level gauges are described on page Gauge glass tubes in chapter Our offer/Technical glass/Borosilicate tubes, rods and capillaries.
The length of the tube should be calculated from the formula:
Length of tube = distance between heads L - 28 mm
