The DCS can be ordered with any length of sensor stem up to 5975mm (19’ 7¼”). The stem length is the active measuring length of the sensor and should not be confused with the stem depth. The stem depth is 60mm longer and includes the non-active section above the measuring length. The stem depth (measuring +60mm) is the length from the shoulder of the mounting thread to the end of the stem probe (Non-standard mounting may have a different length of non-active section).
The DCS IS is suitable for measuring non viscus liquids with a dielectric constant (also known as relative permittivity) shown in the tabulated data above. Viscous liquids may produce a delayed level reading, block the sensor stem and eventually dislodge the internal stem spacers.
The sensor stem is constructed from a stainless steel 316 tube around a stainless steel 316 solid rod. The rod is held centrally inside the tube using a PTFE spacer with cut outs to allow the liquid to flow inside the tube. A breather hole at the top of the stem equalises the air pressure.
