An automatic tank gauge is an electronic device, whose basic function is to monitor the fuel level in the tank over a period of time to see if the tank is leaking. It can also tell the facility operator what is going on inside the tank (example: fuel level, volume and temperature, water level and volume, high and low fuel level warnings). Other features can be added to the Automatic Tank Gauge so that it can perform useful functions such as monitoring the interstitial spaces in tanks and piping, monitoring pressurized piping, or communicating remotely.
An Automatic Tank Gauge uses probes located in each tank or compartment to measure fuel and water levels. Each probe consists of a long rod with floats or sensors. The position of the floats tells the Automatic Tank Gauge console how much fuel and water are present in the tank. The probe rod also has thermistors to measure the fuel temperature. A console is typically located inside the facility building, and can include a display, a keypad, a printer, status lights, and a beeper that signals alarm conditions. An Automatic Tank Gauge system may also be connected directly to a computer.
ATG Tank Test Procedure – How to read an Automatic Tank Gauge test report: The Automatic Tank Gauge test report typically provides the basic information about product volume and temperature in the tank at the beginning and end of the test. It also prints out the results of the test, usually “pass” or “fail”. Occasionally the Automatic Tank Gauge may print out a result that is “inconclusive” or “invalid” when conditions are not right for conducting a test over the testing period.
