Analog and HART out

With a robust design and digital signal processing, these meters provide all of the best benefits of vortex technology. The body, shedder, and sensor are all 316L SS for added durability. The NEMA 4X (IP67) converter housing is epoxy-coated aluminum that can withstand harsh process environments. Just as important to the performance of the flowmeter is the design of the converter. All the programming can be done either through the integrated three-button keypad or by using the ABB Magnet Stick and select parameters from the programming menu without opening the converter housing.

When programming the unit, you can set transmitter parameters for the analog output and a limit alarm output for flowrate or pulse output. The electronics allow for filtering and/or a low flow cutoff of the output to limit control disruptions in the event of fluctuating flow conditions. All programmed parameters are stored in an isolated EEPROM for up to 10 years without power.

In order to provide optimum functionality, the flow profile of the vortex flowmeter should be as undisturbed as possible. This is achieved by using a straight inlet section with a length of 15 times the pipe diameters and an outlet section of 5 times the pipe diameter.
