Takeaway
Yokogawa EJX dual-flange DP combo is a long-standing density solution for large storage tanks — high combined accuracy, mature ecosystem. PS7300 provides integrated solutions (A/B/C variants targeted to specific mounting scenarios) — simpler system, dramatically shorter commissioning. For projects with tight space or fast-commissioning needs, PS7300 is the stronger choice. Yokogawa suits refinery tank farms already standardized on the EJX transmitter family.
