Our 3/4" Water Meter (SPWM-075-CF) and 1.0" Water Meter (SPWM-100-CF) have both received California Type Approval from the California Department of Weights and Measures. This certifies that the meters' accuracy exceeds the threshold required for revenue purposes, like submetering and billing rental units for example.
