Zedflo Australia  presents the API tank level alarm (TLA) system designed to work reliably and accurately in any type of liquid or liquefied gas at any temperature.
 
The API TLA-500 tank level alarm system ensures complete safety during loading and storage of liquids while allowing storage or shipping tanks to be exploited to full capacity without spillage. The IECEx certified level alarm is designed to meet all IMO and US Coast Guard requirements for tankers.
 
Reliable in any liquid at any temperature
 
Designed specifically for operations in liquids and liquefied gases, the API TLA-500 tank level alarm system is also available in special versions for use in extremely harsh and difficult environments, including versions for Arctic/ Antarctic ambient temperatures and LNG gas carriers.
 
Designed to customer specifications, the TLA can be supplied as a standalone unit on the replacement market or as part of a complete API TSS/cargo control system.
 
Upper level and emergency level
 
Control levels are set at the upper level (95%) and at emergency level (98%) of the tanks. If these control levels are reached during loading, the API TLA sets off an alarm together with an indication of the level reached.
 
The TLA-500 is built on patented acoustic wave technology, which ensures accurate level measurement regardless of the tank’s shape, type of liquid or product temperature. The TLA is installed externally, with only the metal rods inside the tank. Acoustic waves are created by piezoelectric energy in the metal rods.
 
When the liquid in the tank reaches the probe on the rods, the emission of sound waves is attenuated. This change is detected by the piezoelectric unit and signals are transmitted to the corresponding alarms. With only the metal rods inside the tank and no mechanical or moving parts, no routine maintenance is required on the unit.
 
Key features of API TLA-500 tank level alarm system: 

  • Works with any type of liquid and liquefied gas
  • Intrinsically safe level switches
  • Easy installation with no maintenance
  • No electronics inside the tank, only stainless steel rods
  • Non-sensitive to vapour, moisture and foam
  • Automatic self-test
  • Special lengths on request
  • Level switch versions available for most liquids/ liquid gases with high temperature and ultra-low temperature versions available
