How do you respond to a red alarm on the ATG?
TO ACKNOWLEDGE WARNING AND ALARMS: For the TLS-350 ATG, press the red Alarm/Test key. For the TLS-450PLUS ATG, press the Traffic indicator in the upper left corner. This silences the alarm beeper and acknowledges the condition.
What material is used to make fuel tanks?
Typically, plastic fuel tanks are made from these five different materials: high density polyethylene (HDPE), polypropylene (PP), regrind plastic (recycled polyethylene), a plastic adhesive or ethyl vinyl alcohol (EVOH). These storage tanks can be formed by rational molding or blow molding processes.
How long does gas last in an underground tank?
Generally, an underground fuel tank lasts more than twenty years, but this depends on the construction process, material, installation system, maintenance and soil condition.
What is ATG fuel system?
An automatic tank gauge (ATG) 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.
What is a scald tank test?
Statistical Continuous Automatic Leak Detection (SCALD) monitors the product level and temperature in the tank at idle times. The system will continue to monitor the tank until it has gathered enough data to conclude that the tank system is tight, or there is a possible leak.
What kind of plastic are fuel tanks?
High-density polyethylene
High-density polyethylene (HDPE) has been the resin of choice for plastic gas tanks, and production capacity has been on the increase.
What is inside the gas tank?
Gas Tank Structure The fuel pipe is connected to the fuel cap where you insert the gasoline. This pipe leads down into the actual tank which varies by capacity based on vehicle size. Inside the tank the fuel filter sucks up gasoline and sends it on to fuel injectors which then send it on to the engine components.
How deep are underground fuel tanks?
Steel tanks can be buried deeper than 5 feet. Steel tanks can be marked to meet UL 58 or UL 1746 requirements with any burial depth required, but no less than 5 feet.
What are underground fuel tanks made of?
Underground storage tanks (known as USTs) are large containers placed underground to hold large quantities of liquids or gases. USTs are typically constructed of Steel, Aluminum, Fiberglass or a combination of materials. They may be either single-wall or double-wall construction.
How is the interstitial space manually monitored?
If a double-walled tank is monitored for leaks using visual monitoring, the operator must manually check the tank’s interstitial space every month for fuel or water. When the metal cover is removed, the operator will find a cap that seals the top of the pipe that leads down into the tanks interstitial space.
What is a Veeder Root?
A Veeder Root system is an automatic tank gauge (ATG) that can be programmed to monitor several aspects of the use, compliance, and performance of an aboveground or underground storage tank. Veeder-Root is the world-leading designer and manufacturer of a full line of ATGs.
