TrueCap RF Capacitance Level Sensor Model MK-2e - Operation Manual

Material Flow - When selecting a location for the MK-2e, choose a point in the vessel where the probe will be out of the direct flow of incoming and outgoing material to prevent any mechanical damage that may be caused by the pres- sure of the flow. The MK-2e must be positioned at a point where incoming material will reach and cover the probe in its normal flow, and when receding, will flow away from the probe in an even manner. For best results, choose a posi- tion where a majority of the probe, not just the tip, will be covered. This is particularly important when detecting mate- rials with low relative dielectric constants and low product densities. The unit will not operate as a “tip sensitive” device. For extended length models, allow for at least 8 to 12 inches (203-305 mm) of probe coverage. When sensing highly conductive materials, or those with a high dielectric constant, the MK-2e can perform as a “tip sensitive” sensor.
