1. A system that permits assessment of performance of a reverse osmosis membrane element, comprising:
- said reverse osmosis membrane element;
a permeate tube within said reverse osmosis membrane element;
an elongated probing tube within the permeate tube of said reverse osmosis membrane element;
at least one sensor configured to measure a value used to assess said performance and disposed at an inlet side of said probing tube; and
a recording device in electronic communication with said sensor so as to record results of said measurement.

Abstract
The present disclosure relates to a system comprising integrated sensors (169, 170) for measurement of permeate flow and permeate conductivity of individual membrane elements (163) while they are in operation in an RO unit. The flow and conductivity measuring integrated sensors (169, 170) are of a small size that enables them to be inserted into the permeate tube (172) of connected membrane elements (163) during RO unit operation. Measured flow and conductivity information is transferred to the recording device (174) through electric wires or through wireless transmission.
