The Bolod vortex flow meter DVH utilises three primary sensing elements: a vortex-shedding velocity sensor, an RTD temperature sensor and a solid-state pressure transducer to measure the mas flow rate of gasses, liquids and steam.
Systems that use external process measurements may not provide adequate compensation for the fact that process conditions can change radically between the point of velocity measurement and the point where upstream or downstream pressure and temperature measurements are being made. Because the DVH multivariable flow meter measures all of these parameters in a single location, it delivers a more accurate process measurement.
Integrating multivariable output capability with a single line penetration also simplifies system complexity and helps reduce initial equipment cost, installation cost and maintenance costs.
