Interface Wipy with water flow meter

[Ricardo85]

For interfacing water flow meter with WIPY, I wanted to send the digital data to get converted into analog output of 4-20mA current range (which is very old and good solution to control the meter) but as I am new to 4-20mA current loop field, What is the best low power DAC module to interface flow meter easily with wipy?
your suggestion will be appreciated

Hi @ricardo85
Can you share what water flow meter you're planning to use?

Are you sure you want the WiPy to be a transmitter or a receiver?
