Diesse DS LG-RCR GR18

This type of gauge is recommended:

• for taking clear and simple readings (see counter-indications below)
• if you are looking for an inexpensive gauge which will also save you money on maintenance costs

Operating limits / Conditions:Process:

• Max. pressure: 255,5 bar @ 38°C (rating class 1500)
• Max. temperature: 300°C (max. temperature allowed by borosilicate glasses as per the DIN 7081 standard)

Steam:

• Max. pressure: 22 bar
• Max. temperature: 216°C (saturated steam @ 22 bar)

Note:For saturated steam values > 20 bar, a low-maintenance transparent level gauge with mica shield protection should be used (see graph glass loss caused by boiler water for the estimated glass life).Not only does the glass life depend on the temperature, it depends on the pH of the water (the higher the value, the shorter the glass life).The product is NOT suitable for use in the following instances:

• if exposed to corrosive fluid (e.g. caustic soda, hydrofluoric acid, citric acid...)
• if exposed to high pressure steam
• if subjected to repeated thermal shocks

In the scenarios listed above, the glass must be protected with MICA or PCTFE shields, so a transparent level gauge is necessary

• for checking the level of separation between two immiscible fluids (interface)
• for checking the colour of a fluid (all fluids look very dark)
• in cases where the fluid is particularly viscous (a film may form on the glass which prevents you from taking an accurate reading)
• in cases where the fluid is particularly dark (the reflex principle is rendered ineffective)
