Fluid level sensor

21 July 2010 Test & Measurement

The eTape sensor from Milone Technologies is a solid state, continuous (multilevel) fluid level sensor for measuring levels in water, non-corrosive water-based liquids and dry fluids (powders). The sensor is manufactured using printed electronic technologies which employ additive direct printing processes to produce functional circuits.

The sensor’s envelope is compressed by hydrostatic pressure of the fluid in which it is immersed, resulting in a change in resistance which corresponds to the distance from the top of the sensor to the fluid surface. It provides a resistive output that is inversely proportional to the level of the liquid. The sensor’s total length is 363,2 mm, with an active length of 320,7 mm and resolution of 0,794 mm. It provides an output of 550 Ω when empty and 60 Ω when full and is rated to operate between -9°C and +60°C.
