Water flow usage meter and automatic shutoff

[Jean Castillo]

Hi,

One of my properties had a hefty water bill due to inconsiderate tenants using more water than needed and I would like to install a water flow meter that has a cap per day (landlord pays for water/sewage). Essentially, I would like to assign each unit a usage of "x" gallons per day before closing the water valve when threshold is met to regulate the units. I've done research but most of what I've found is for emergency use (leak systems) or just plain monitoring without automatic shutoff. Can someone point me in the right direction for this? A brand that's recommended for this? Thanks in advance.
