Barrow LRC 2.0 G1/4" RGB Flow Meter - Clear/Black (SLFV1-RGB)

Product Review (submitted on December 19, 2019):

The spinning wheel definitely provides peace of mind when my pump is running at low speed and there are no other signs of movement. The RGB looks really great, but you need to buy this ZBDZJX-5 in order to connect it to a standard 3-pin RGB connector.
