Ex Delta II DIA Vortex Flow Meter

The EX DELTA II DIA Vortex Flow meter  – OVAL’s proprietary diamond-shaped vortex shedding body together with the sensor location apart from the bluff body sensor results in a consistent performance in measuring dirty liquids containing materials such as scale, dust and other contaminants. It is available either with a standard fixed sensor or with a replaceable sensor.

They are particularly suited to long-run processes or on-site instrumentation where the utmost reliability and ruggedness are required. The standard Smart EX DELTA is also available as a battery powered unit requiring no external power source, where the battery pack has a 7 year life based on a 24 hours a day operation. In areas where pipelines are densely installed, or in elevated or hazardous locations, a remotely mounted indicator may be preferred. The indicator can be mounted up to 200 mm from the basic flow meter, allowing the operator to monitor a number of widely distributed flow meters from a central control. Display options include total flow (resettable), instantaneous flow rate, % FS instantaneous flow rate, % FS bar graph.
