DAT instruments dataloggers are being used in the Riyadh Metro Project. The task consists of the six underground lanes of within the Saudi capital city.

The construction of the tunnels and all the stations beneath the stratum level has required a geological study focused on soil permeability. The DAT instruments partnered consulting company is, in facts, the local member in charge of the test, undertaking double packer tests combined using DAT instruments Lugeon/Lefranc Test datalogger, The JET DSP 100/IR, in order to understand in real time and record water flow, pressure and final volume. Data, which are fundamental for performing both accurate design construction of all tunnels and all the stations, are extracted from the Italian company's dataloggers.
