Accelabar is a new and unique flow meter that combines two differential pressure technologies to produce high accuracy and low velocity flow rates at turndowns tested up to 65:1 with no straight run requirements.
The Accelabar consists of a unique toroidal nozzle design and a Verabar averaging pitot. The nozzle has a patented "settling distance" that accelerates, linearizes and stabilizes the velocity profile sensed by the Verabar. The Verabar located within the nozzle accurately measures and significantly increases the differential pressure output to increase the operating range (turndown).
The Accelabar can be used in extremely limited straight run piping configurations. The straight run is integral to the meter. The stabilization and linearization of the velocity profile within the throat of the nozzle eliminates the need for any upstream run.
