Level measurement for liquids
This measuring method is very simple. A calibrated bypass tube is connected to the side of a tank or vessel at the top and bottom so the levels in the tank are replicated in the tube and the changes in the tank, equal changes in the bypass tube.
There are then two options for level display utilising a float inside the chamber with a magnet inside which travels up and down the tube changing magnet flaps on the outside of the tube indicating the height of the liquid in the tank with a clear visual display.
The bypass tube also offers the option to install a level sensor into it for an electronic output of level or contents. This can be done with either a Radar or TDR level instrument. This provides a clear visual display of contents and an analogue output for retransmission of the signal if required.
Temperatures can be as low as -200ºC and as high as +300ºC and materials of construction can be provided to cater for corrosive or hazardous media. Pressure ranges are from vacuum to 120 bar.
