I use a badger BR25 5/8 x 3/4 BRZ meter body, the M25 Generator and M25-M70 remote read

Remember when doing this you need to know how you are reading the water, gallons, cubic feet, cubic inches etc…
Ah… my last invoice had the meters, generator and remotes at 78.50 each. I was ordering 60 of that so that might reflect a discount for the volume of meters…
