Near Intersection of I-35 & I-90 Southern Mn. | One year I misplaced my Raven flow max system. There are a couple of different models based on Raven turbine flow meters. My dealer did not have one on hand but suggested the BanJo Mag type meter. I purchased one but was unhappy with it.
Later I found my Raven and went back to using it.
I have since made a homemade arrangement using a microcontroller and a Raven flow meter. I call it my "Batcher". Pictures of my Batcher are shown below. I have a display mounted on a two wheeled cart above my electric transfer pump. The third picture is a large remote display which shows the running batch total wirelessly in my mixing shed. That way I can consult either display as I'm making a batch.
I will be working on a new better remote display this Winter.
I have also purchased some standalone battery powered 3" flowmeters through the Chinese. The actually work very well but the problem with them was they used an odd thread which was neither NPT or Metric. It was some type of English variation. I was able to obtain some adapters/quick couplers. I actually use both my Batcher and a 3" Chinese flowmeter as a check against each other.
I haven't seen the 3" Chinese model listed lately though. Sorry no picture of them.

Best 3" meter for liquid fertilizer? Also thread sealant.
