Racine® Vortex meters

Racine® Vortex vs. common construction Racine® Vortex flow meters utilize ultrasonic technology to measure tiny vortices that form when media in the pipe move across a strut, or “bluff bar”. The number of vortices formed is directly proportional to flow rate, and the resulting product is a flow meter with high turndown ratio (up to 70:1) and high accuracy (±1% of reading). With Smart electronics and HART® communications, the Racine ® Vortex flow meter is an excellent choice for process plants and refineries. With no moving parts and little or no maintenance required, the meters are also an excellent choice for OEM companies working with water supply, quality or treatment equipment. Typical Vortex shedding flow meters use a large bluff body, often in conjunction with a piezoelectric sensor or pressure transducer. These large bodies are needed in order to generate a pivot, torque or pressure differential of sufficient magnitude (see example below). Racine® Vortex flow meters utilize ultrasonic sensing technology, allowing the meters to perform with an extremely small bluff body. As a result, system pressure drop and meter turndown ratio are greatly improved.
