A level measurement arrangement for measurement of a level of a product in a container, comprising: a level sensor, having: a mounting element, including a process connector, for mounting the mounting element on a mating counter connector on an opening of the container, and a conductive probe segment extending from the mounting element into the container; a conductive probe extension (19), having a first end, which is permanently fixed to an inner wall of the container, and having a second end, which is detachably connectable to an end of the conductive probe segment extending into the container; and sensor electronics comprising elements for generating and sending short electromagnetic pulses down the probe segment and the probe extension, elements for reception of the echoes of the pulses reflected at a surface of the product elements for determining the level of the product in the container, based on a time of flight needed for a pulse to travel down the probe segment and the probe extension, and its echo to return.
