Redesign of the EMS, the Electromagnetic Speed measurement. |
The EMS, the electromagnetic speed measurement, is a device that has been in operation for a long time at Deltares. The first design origins from the 70s and the last major redesign, the pEMS, is from 1993. Small upgrades/improvement were still provided till this day. Last year EFS started work on a upgrade. First by designing a smaller measurement probe, the E20, the probe did not leave the development fase yet. My assignment is to continu the development of the EMS mainly by researching/testing all the different components/subsystems to see where improvement can be made. So far i already looked into: -The magnetic field produced by the different probes configurations Image Added
These measurement were/are going to be used to optimise the core/coil. -Methods to measure faster to increase the turbulence measurement. The theory and the diffenent methods to achieve this. Using one off these techniques a proof of concept for 180hz measurement was build and tried. This showed there was potential. After that a development prototype was designed, build and tested in a small flume and the calibration flume. The goal is to improve/test this prototype till it passes the calibration tests and functions properly in a enviroment with high (electronic) disturbance.<image> <tekst>
