Recently, my company started to produce new type electromagnetic flow meter.

This type flow meter could have 4-20mA and RS485 output, and 24VDC or 220VAC power supply.

It will be very useful for customers who only want to a output from flow meter, and don't need to read the display directly.

4 wires 4-20mA is standard funcation and customer also could choose RS485 as added funcation.
