Ex Delta II Vortex Flow Meter

This basic, affordable model of the Ex Delta series of vortex flow meters includes a range of intelligent functions such as self diagnostics and the capability to review and change parameters. It is available either with a standard fixed sensor or with a replaceable sensor. With the replaceable sensor versions, it is possible to service the sensor without interrupting the process flow or removing the meter from the pipeline.

​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.
