Honeywell Enraf 954 Smart Servo Advanced Tank Level Gauge

Built to replace the retired Enraf Servo 854 tank gauge, the 954 Smart Servo adds enhanced software alogirthms, adaptive dynamic compensation, and advanced drum calibration for better performance in even more challenging applications. The Enraf servo gauge meets all international standards and is SIL-rated for reliable operation.

Honeywell’s 954 smart servo tank gauge measures liquid level, density and water interface level measurement with the highest accuracy available in the marketplace. It's designed with minimal moving parts and a modular construction for easy maintenance to help you drive down operational costs.

Suitable for product and gas temperature with spot or average temperature measurement or temperature profiling, product level, interface level, desnity measurement and profiling, average continuous density monitoring connecting one or more HART pressure transmitters, direct water bottom measurement via conductivity probes.
