Third-party contract measurements for oil and gas, petrochemical products, gas hydrates and more
PSL Systemtechnik offers extensive third-party contract measurements in the area of Flow Assurance, crude and live oil, petroleum and petroleum products, gas hydrates and physical properties.
For this we adapt the test parameter to your needs and provice test facilities beyond the typical standard procedures. Customer specific adaptations of our instruments and completely new test set-ups are possible.
