Coloured indicating liquid for mechanical remote level gauges
For our long-lasting mechanical level gauges fitted into existing systems we were until recently because of manufacturer difficulties no longer able to supply coloured indicating liquid (red). As an alternative during this period a transparent sealing liquid with a red float was supplied; however this lead to some extent to problems through operating errors in servicing.
In the meantime together with another manufacturer we have developed a new colour. Because of the process it is now not red but blue but still enables a clean and clear indication. The liquid is completely inert to water and above all environmentally safe.
Depending on type of gauge the density is 1.68 and 1.78 and upon request even 1.93 kg/dm³.
