MyTankGauge has saved our butts several times when/if there is a discrepancy or if a driver domes out. I can look to see how much product was dropped in each tank and immediately know if we have a crisis (cross drop) or a minor incident (NL on NL or NL on PNL) going on.
I tell people all the time, out of all of the tank monitoring sites that I have been privy to, MyTankGauge is by far and above the most user friendly and easy to navigate! It has everything one could want right there! You don’t have to hunt for it.
