Water meter bucket test

GOAL: Test home Water Meter (WM) accuracy.
RESULT: 14% off. Water meter measured 14% higher usage than actual.
OBSERVED: Water bubbles in water.
RESULT: 14% higher report by WM might be consistent with air solubility in water @40F. See below.

Test date: February 23, 2020
Test time: 17:08:21
Location: Plainfield, IL (LF)
Water supplier: Romeoville, IL
Water meter (WM): Badger E-series
Bucket size = 5 Gallon.
Outside temperature = 51F
Water pressure = 70 [psi]; Measured using Orbit 91130 Water Pressure Gauge.
Water Pressure Gauge from: https://www.walmart.com/ip/Orbit-91130-200-PSI-Water-Pressure-Gauge/42501018?wmlspartner=wlpa&selectedSellerId=10&adid=22222222227030390602&wl0=&wl1=g&wl2=c&wl3=61027249871&wl4=aud-430887228898:pla-109711303031&wl5=9021685&wl6=&wl7=&wl8=&wl9=pla&wl10=8175035&wl11=online&wl12=42501018&veh=sem&gclid=Cj0KCQiA4sjyBRC5ARIsAEHsELHbjx5dyJreP_it6fJg9d2D3UPI8y-F87o-tR73KQhLE9BIjM76Z_EaAmoMEALw_wcB

Water usage measured by WM= 5.68 Galon = 91,997.48 - 91,991.80 = {Final - Initial WM reading}. Water meter measured usage is 0.68 Galon higher than actual water in 5G bucket.

Solubility of air in water near temperature of 40[F] and pressure of 70[psi] is about 15%.

PLAN: Repeat the test, and gain some statistics.

Stay tuned, and happy science.
