data sheet date vortex flowmeter (eggs delta) EDS6-121A aug. 5, 2005 fmp, m this instrument is a karman vortex flowmeter made of pps resin that can be used both for liquid and gas. it has no moving parts. it does not shut the flow even in the case of an emergency, which makes it most suitable for not only in general flow control applications but also in important washing processes and cooling processes, and in the ter- minal consumption control such as in factory air control. the exclusive monitoring instrument is a battery charged type and does not need external power supply. orienta- tion of the indicator can be adjusted freely to easy-to-see direction. features 1. the monitoring mode can be changed freely from total flow monitoring to instantaneous flow rate monitoring, and vice versa, by an externally mounted mode switch. 2. a rainproof type is available for outdoor use as well as for indoor use. 3. the highly durable structure with no moving parts does not impose limitations to its mounting positions. 4. the instrument is highly resistive to fouling by fluid, and its structure facilitates cleaning of its interior. 5. remotely controllable external output (total pulse or instantaneous analog) is available.
