The EESIFLO Hybrid Spool is is available in pipe sizes ranging from 4 to 42 inches and from 150 ANSI to 1500 ANSI . It can be installed in general industry applications and in also in hazardous environments (Zone 1) . Spool piece construction materials are available in Carbon steel, stainless steel and Duplex. The Hybrid has been designed to work in flow applications where transducer mounting is fixed and cannot be easily tampered with. The system employs either single or dual path permanently coupled non-intrusive ultrasonic sensors mounted to a spool. This configuration provides full flow and zero pressure drop. The measurement technique used enables reliable flow data even during temperature fluctuation, a high turn-down ratio and ability to work at high temperatures. Advanced ultrasonic transducer technology combined signal processing optimized for speed and robustness, provide the capability of the system to operate even in applications where conventional meters are unable to operate due to technology constraints over extended time periods.

The Hybrid spool is an alternative to wetted transducers which protrude into the pipe . The spool pieces are manufactured with smooth walls which increase signal attenuation and without the use of any form of grease or couplant between the sensor and pipe wall. This has great advantages in many applications where coupling compounds are not practical. The positioning of the sensors allows for some degree of change in refractive index due to a change in the liquid make up or temperature so that the signal is not lost from process variations. This could include temperature changes or some liquid variations . The non-intrusive sensors and electronics are not affected by process conditions and do not experience sensor coating or fouling enabling the system to work for extremely long periods of time and are maintenance free.

The Hybrid system is ideal for use wherever accurate, reliable and economical long-term flow measurement is critical to process and product quality. This includes applications such as hot /cold water mixtures of water/oil , produced water , fossil fuels and high temperature flow measurement. Measurement is non contaminating, obstructionless and causes no pressure drop.
