| Operation
When fluid flows through the unit it displaces the Teflon®-encapsulatedmagnetic piston.
This displacement is proportional to the volumetric flow through the unit. A transducer,
encapsulated in the body outside the fluid path, senses the displacement of the piston.
The transducer’s signal is converted by a microprocessor-based conditioning circuit then
sends the signal to three types of outputs: voltage, pulse and current loop.
• TOTAL ACCURACY: ± 5%
• REPEATABILITY: ± 2% FULL SCALE
• LINEARITY: ± 2% FULL SCALE
