VorTek Instruments’ VorCone™ flow meters utilize two different flow meter technologies in combination; vortex and differential pressure. This combination allows for the prediction of the fluid density, volumetric flow rate and mass flow rate without any fluid density information being required from an external source. In saturated steam service, the meter produces a reliable steam quality (dryness) measurement and steam mass flow rate reading.


VorTek Instruments’ Pro-V™ multivariable flowmeters utilize three primary sensing elements–a vortex shedding velocity sensor, an RTD temperature sensor, and a solid-state pressure transducer–to measure the mass flow rate of gases, liquids and steam.


Insertion vortex meters measure flow by detecting the local velocity at a strategically located position within the pipe. Our Pro-V™ Model M23 detects the frequency at which vortices are shed from the bluff body located within the sensor head and then converts this to a volumetric flow in the electronics. The Pro-V™ Model M23 also uses the local velocity, along with other parameters, such as fluid type, pipe size and Reynolds number to calculate the average pipe velocity, and consequently, the volumetric flow rate.
