The word environment applicable to this report
is defined as:

Physical surroundings and conditions especially as affecting peoples lives, conditions and circumstances of living.
External conditions affecting the growth of plants and animals.

1.
The environment.
2. High level alarms and petro-chemical.
3. Marine vessels using 'high' and 'high high' level alarms (world regulations US coastguard)
4. High level alarms and pump control within the marine environment.
5.
Interfacing liquid detection.


1. The environment.
Governments and regulating authorities around the world are at long last concerned about the environment. As you can see from the definition above, the word environment relates to people, animals, plants, their conditions and surroundings. Many companies especially those whose operations have a profound effect on the environment are working to, or are implementing environmental management systems to BS ISO 14001 : 1996. The general public and the environmental lobby often view engineering and engineers to be the cause of many of the world's environmental problems. It is true that many everyday things that we take for granted for example, the motor car, refrigerators, cookers, washing machines, televisions, computers, things which have become part of our every day life were designed by engineers, and are manufactured by engineering companies. All these items have an environmental impact, however how many of us would be prepared to give up some of these items. Engineering is also involved in systems to protect the environment, one extremely important role that engineering has in caring for the environment is the control of fluids and fluid levels. The control of fluid levels is essential in protecting the environment from the over fill of simple tanks containing household fuel oils to the most complex process control tanks & storage vessels in industry.

2. High level alarms and the petro-chemical industry.
Due to its high public profile the petro-chemical industry is very aware of its duty to have all the necessary environmental protection equipment & procedures in place. TAV Engineering supply high and high high level control instruments, which are fitted in the top of fuel storage tanks, and are often fitted with manual check systems. This allows the user to check that should the tanks start to overfill, the pumps filling the tanks are automatically shut down, and the alarm systems operated. If fuel spills from a storage tank and contaminates the land and ground water systems, then the environmental impact could be enormous risking the lives of people and animals. The clear up operations are expensive, and extremely difficult to carry out effectively.

3. Marine vessels using 'high' level alarms (world regulations US coastguard).
Marine tankers carrying fuels, oils and chemicals cannot enter American waters under the auspices of the US Coastguard unless the tanker is fitted with High level checkable level sensing systems. TAV Engineering are world leaders in the manufacture of High-level manual check level switches.

4. Level alarms and pump control within the marine environment.
Level switches operating High level and low level alarms are used extensively in the marine industry to take care of all the various tank systems aboard a ship from the bilge's to the heavy fuel oil storage tanks, looking after the ships personnel & the ships tank outlets. Preventing spillage into the sea.

5. Interfacing liquid detection.
Any area where oils and fuels exist will always be subject to spills and contamination. In a very small way you will have seen an example of this if you have ever washed your bicycle. The water often carries oil from the chain and other areas away onto the ground, the colour haze you see on the surface of the water is the oil film. Imagine if this were to be allowed to happen on a large scale, rainwater would wash the fuel or oil into the soil or ground water system. Sites at risk to such contamination are normally designed with rainwater 'run off' channels and storage tanks where the water & fuels etc. are collected. These storage tanks are called interceptors it is here that the liquids coming in are allowed to settle, because water is heavier than the oils and fuels the water sinks, leaving the oils and fuels floating on top. These interceptors are normally fitted with level control device's which sense the interface between the water and the fuel, in this way the levels of water and the fuel layer can be controlled. Preventing the fuels and oils from contaminating the soil and ground water system.
