  The ESS beam instrumentation includes 3 different type of Wire Scanners (WS). Double wires systems are deployed in the MEBT part of NCL, and single wires and flying wire instruments are being tested and installed in the higher energy sections of the ESS linac. First beam tests result from the MEBT systems will be presented. The superconducting linac WS systems are based on scintillator detectors and wavelength shifting fibers are mounted on the beam pipe. The detectors are coupled to long haul optical fibers, which carry the signals to custom front end electronics sitting in controls racks at the surface. The acquisition chain have been characterized at IHEP (Protvino, Russia), ELETTRA (Trieste, Italy), CERN PSB, CoSy (IKP, Germany) and SNS (USA) before installation in the ESS tunnel. The test results of this system design, differing from the standard approach where photomultipliers are coupled to the scintillator will be presented.
