DELTA FLOWPET-DX/High accuracy and inexpensive with pressure compensation

(Without pressure compensated) (With pressure compensated)
(Without pressure compensation)

(With pressure compensation)


DELTA FLOWPET-DX (with pressure compensation) piezoelectric DELTA vortex flowmeter combined with a built-in pressure sensor. It measures mass flows of saturated steam and gas with corrected for pressure. Liquid, gas, and stream are measurable for volume flow measurement.



Incorporation of a pressure sensor and pressure correction circuitry reduces instrumentation cost and simplifies the system.


Both analog and correction pulse outputs are available at the same time.


Easy to maintain, reducing maintenance cost and enhancing safety.
