Product Critical Technical Advantages
-
Engineering excellence in loop-powered technology allows for the seamless integration of a high-performance Coriolis meter into existing 2-wire architectures. This genuine loop-powered design reduces the complexity of power supply requirements and cabling costs without compromising the accuracy or multi-variable data output of the sensor.
-
Precision engineering for micro-flow and high pressure enables accurate measurement at DN 1 to 4 (1/24″ to 1/8″) line sizes with pressures reaching up to 430.9 bar (6250 psi). The single-tube design is specifically optimized to capture mass flow and density data for minute quantities, ensuring tight control in high-pressure chemical dosing.
-
Highest operational safety in hazardous areas is achieved through an intrinsically safe design (Ex ia). The Promass A 200 is built for global compliance (SIL, Hazardous area approvals), providing peace of mind when measuring volatile or reactive fluids in explosive atmospheres.
-
Integration of operational intelligence through Heartbeat Technology enables “in-situ” verification of the meter’s health. This ensures that the measuring tube remains within factory specifications and provides a documented verification of plant safety without requiring a process shutdown or removal of the device from the line.
-
Robust dual-compartment housing with touch control allows for safe operation and wiring. The separate connection compartment protects the electronics from the environment, and the backlit display with touch control means the device never needs to be opened in the field—even in hazardous zones—maintaining the integrity of the explosion-proof protection.
-
Self-drainable single-tube geometry ensures that no residual process fluid remains in the sensor. This design is highly resistant to internal clogging and allows for easy cleaning, which is critical for maintaining product quality and preventing localized corrosion when handling aggressive specialty chemicals.
