We are pleased to announce our latest representative for Verabar® and Accelabar® products: Combustion Technology

Now … There is a Difference

Developed from aerospace technology, the Verabar bullet shaped differential pressure flow sensor with dual low-pressure ports located on the sides significantly improves accuracy, rangeability and resistance to clogging. The Verabar works where other insert flow meters have failed. It accurately measures gases, liquids and steam in pipes and ducts.
Superior Signal Stability and Greater Resistance to Clogging
Clogging occurs in low-pressure ports located in or near the partial vacuum at the rear of the sensor. The Verabar design locates the low-pressure ports on the sides of the sensor, forward of the fluid separation point and turbulent wake area. This virtually eliminates clogging and produces an extremely stable signal.

Lower Drag and Extended Turndown

Golf balls fly farther because they have a dimpled surface that lowers aerodynamic drag. The grooves and roughness on the Verabar’s frontal surface apply the same principles. This simple design feature relieves the partial vacuum at the rear of the sensor, reducing the pressure drag. This extends the accuracy and range-ability to very low velocities.

In God We Trust … All Others Bring Data

The unique and exclusive breakthrough in improved accuracy is derived from a verified mathematical model to predict the Verabar flow coefficients. This eliminates the need for calibration tests to characterize the coefficients. Without such a model, the uncertainty of the flow coefficients is dramatically increased and expensive calibration may be required. Empirical test data from independent laboratories verified the theoretical model and Verabar flow coefficients as a constant, independent of Reynolds Number and within ±0.5% of the predicted value.

New from Veris Engineering – the Accelabar®

A new and unique flow meter combines two differential pressure technologies to produce operating ranges never before attainable in a single flow meter, capable of generating high differential pressures for measuring gas, liquids and steam at turn-downs tested up to 65:1 with no straight run requirements! The Accelabar has a constant flow coefficient and produces an accuracy of ±0.50% over the entire operating range – other manufacturers claim high accuracy but over a limited turn-down.
