TA-Smart-Dp

2-way Smart electronic differential pressure controller with flow, temperature and power measurement capabilities

The ultrasonic flow measurement technology combined with unique actuation algorithms capabilities provide best-in-class control performances. TA-Smart-Dp is designed to keep a stable differential pressure over the load. This enables accurate and stable conditions to provide superior control valve authority for modulating control valves, additionally it can limit noise and simplify the balancing procedure. Its compact arrangement and simple set-up reduces installation and commissioning time.
