Abstract
The concerns a measurement device and system utilizing the same for precise measuring the fluid level in a container, the measurement device (10) being located outside of the container (12) and comprising a predetermined number of basic blocks of a predetermined geometry, the basic blocks comprising at least one pair of capacitors with a predetermined relation between their capacitance a differential change in said relation along the device (10) being indicative the fluid level condition in the container (12).
Claims17
A measurement device for measuring a fluid level in a vicinity of the device, the measurement device comprising a capacitance-based fluid level sensor with a predetermined number of basic blocks of a predetermined geometry, the basic block comprising at least one pair of capacitors with a predetermined relation between their capacitance, a differential change in the relation along the device being therefore indicative of the fluid level condition in the vicinity of the device, the capacitance-based fluid level sensor comprises an elongated structure having a longitudinal axis and carrying an electrodes' arrangement defining the at least one pair of capacitors.

(canceled)
A capacitance-based fluid level sensor comprising an elongated structure having a longitudinal axis and carrying an electrodes' arrangement defining a predetermined number of basic blocks of a predetermined geometry, each basic block comprising at least one pair of capacitors with a predetermined relation between their capacitance, said relation being common for all the basic blocks, a differential change in said relation along the sensor when exposed to fluid environment being therefore indicative of a fluid level condition in the vicinity of the sensor.
