The ESI-USB© software allows you to connect your ESI transducer to your laptop or PC and be up and running monitoring pressure data within ten minutes. The software auto-updates and is compatible with Windows 8, 10 & 11.
Differential pressure measurement is essential across industries, providing critical insights into fluid flow, filtration efficiency, and system performance. Unlike absolute or gauge pressure, it measures the difference between two points, making it invaluable for HVAC systems, process industries, and fluid level monitoring.
Why Differential Pressure Matters
Measuring differential pressure helps maintain efficiency and safety in various applications:
Filtration systems – Identifies when filters need maintenance.
Flow measurement – Enables accurate fluid flow calculations.
Tank level monitoring – Provides precise readings in sealed tanks.
By tracking pressure variations, businesses can optimise processes, reduce downtime, and ensure compliance.
