Ultrasonic Vortex Gas Flowmeter

? Rockwin proffers its wide range of ultrasonic vortex flowmeters in technical co-operation with j-tec, usa. These meters are ideally suited for industrial metering of bio-gas, steam, combustion air, etc. They are also suitable for flare stake monitoring, etc. These meters work on the principle of vortex shedding. When a gas flows past an obstruction, vortices are created in a fixed, predictable pattern. The number of vortices shed downstream per unit time is proportional to the flow rate. The measurement of vortex shedding is through patented ultrasonic sensing. It offers a rangeability of 1:70 with almost negligible pressure drop. The wafer series is available from 10 to 100 mm with flow capacities up to 18,000 m/hr. The insertion series is available for pipe sizes varying from 150 mm and above, with a velocity range from 0.6 to 56 m/sec. These meters are compatible with a wide range of rockwin electronic read out units comprising totalisers, batchers, flow rate monitors, flow alarms, various outputs and dedicated flow computer
