The Unique Accelabar Flow Meter The Accelabar is a new and unique flow meter that combines two differential pressure technologies to produce operating ranges never before attainable in a single flow meter. It is capable of generating high differential pressures for measuring gas, liquids and steam at turndowns previously unattainable — with no straight run requirements. RTD (optional) Verabar How the Accelabar Works The Accelabar consists of a unique toroidal nozzle design and a Verabar averaging pitot.
Verabar Provides the Accuracy The proven technology of the Verabar makes the Accelabar work. It accurately measures the flow rate within the nozzle. Its unique bullet shape, constant flow coefficient, solid one-piece construction, non-clog design and signal stability make it the only design capable of producing the overall performance.

Comparative Analysis vs. Other Flow Meters The Accelabar fills the need not presently being filled by other flow meters for applications that: Flow Turndown Maximum & Minimum • Do not have sufficient velocity to produce a readable signal or sufficient turndown • Require the highest accuracy over an extended range • Have little or no straight run piping before the meter The Accelabar performance characteristics far exceed those of other DP meters, vortex meters and many other flow meters.
The Proof Is In The Data Many flow meters claim high accuracy and rangeability or turndown. However, few manufacturers define their limitations and even fewer can support it with actual test data. The tests below show the performance capabilities of the Accelabar.

Ready to Install Dual Transmitter The Accelabar is a complete flow meter ready to install. It comes complete with single or dual transmitters depending on the turndown requirements. Single Transmitter An optional RTD is supplied in a Thermowell for dynamic compensation (required for use with multivariable transmitter).

Transmitter Selection Accelabar accuracy is percent of rate. The Accelabar maintains a constant flow coefficient over a wide range of flow rates and differential pressures. Single Transmitter Dual Transmitter DP transmitter accuracy is percent of scale. While most Accelabar installations are equipped with one DP transmitter, some applications requiring superior accuracy over an extreme DP turndown may require a dual DP transmitter installation.
