  • Page 4: Regulation Use

    4. Regulation Use Model DSS instruments monitor liquid flows. Only clean, homogeneous liquids of low viscosity - against which the instrument materials are resistant - should be monitored. Large switching inaccuracies may occur with highly viscous media. Large dirt particles can block the float and thus cause faulty signals. Pieces of ferrite deposited on the embedded float magnet can also cause problems.
