How does a tank gauging system work?
Hydrostatic tank gauging utilizes up to three pressure sensors and one or more temperature elements. The hydrostatic pressure (liquid head) is measured; as the height increases the pressure increases as well. If a single pressure sensor is used, a manual density measurement is required for an inventory calculation.

API 650: Tank Design
Very little of the content of all the API 650 appendices ever appears in the API 653 exam. There is far too much of it, most of which is of little practical necessity to API 653 storage tank inspection. Picking through the published API body of knowledge (BOK) reveals the few bits of the appendices that are included:
Inspection
Standards for test, inspection, and repair methods for storage tanks are given in Table 3.1. Of these probably the most widely used is API 653—Tank Inspection, Repair, Alteration, and Reconstruction (API, 2014c ).

If the inspection reveals corrosion concerns, a corrosion expert must evaluate the existing protective measures, and recommend actions to ensure the integrity of the tank system during its use.
What equipment is required to protect against excessive settlement, vibration, expansion, or contraction?
Ancillary equipment including piping, fittings, flanges, valves, and pumps require support and protection from excessive settlement, vibration, expansion, or contraction. If ancillary equipment is not inspected daily, it must have secondary containment.36
What is the tank system?
Tank systems must be equipped with spill and overfill prevention controls17. A tank must have some form of high liquid level indicator or liquid level pump cutoff device to prevent overfilling. The indicator may be audible or visual and must be designed to work well in its operating environment. The liquid level sensing device must be tested regularly.

Why is wastewater treatment important?
Why Waste Water Treatment is So Important. All around the world, it’s common practice to pump enormous volumes of wastewater into rivers, oceans and streams. This has extremely negative effects on the environment, fisheries, animals, and that’s not to mention it’s an aptly named ‘waste’ of water too.
What is wastewater treatment?
Wastewater treatment is a process that coverts wastewater from its unusable state into an effluent that can be either returned to the water cycle with minimal environmental issues or reused for another purpose.
Why is assessment important before massage?
Why are assessments so important before a massage treatment? When considering a sports massage treatment or rehabilitation to assist with recovery from a sports injury or for therapeutic and health benefits , it is important that the massage therapist conduct an assessment before the treatment takes place. Below, we round up the reasons why.
Why is it important to do an assessment?
Another reason why the assessment process is so important is that it allows the therapist to check your medical details, and establish whether there is a contraindication. In simple terms, a contraindication is a condition that restricts the therapist from conducting any treatment on a client, so we have to rule out any contraindications.
What issues should be ironed out before massage?
Other issues that must be ironed out before treatment are high or low blood pressure, diabetes, acute inflammation, and serious diseases such as cancer , where the therapist would likely ask you to check with a GP before a massage treatment is carried out.

Why is initial consultation the longest?
Your wellbeing is their top priority, so an initial consultation will usually be the longest, in order for the therapist to truly understand your needs in the treatment room and to identify what your treatment needs are and explain accordingly.
Why are there different levels of risk associated with each tank?
Different levels of risk are associated with each tank because the filling rates are different , sensors have differing reliability and other factors that can influence the tanks (see Figure 2). The likelihood of an overfill event requires tank-specific information such as filling rate, installed instrumentation and other data.
What makes tank overfilling hazardous?
What makes a tank overfill uniquely hazardous is that it can generate a deadly vapor cloud, which can flow out far past secondary containment, resulting in a detonation and hazardous conditions for nearby communities. One example that had a major influence on API 2350 is the Buncefield fire in 2005.
What is risk analysis?
The risk analysis process incorporates the results of data collection, organization, analysis and assessment. For example, specific tank information such as filling rate, previous spills/near misses, operator reliability, implementation of automatic overfill prevention system (AOPS) and gauging system reliability can be compiled and included in the analyzer’s database. In addition to data on size and frequency of events, the severity of various failure modes is also included. For example, the severity of an overfill or spill event may be influenced by the filling rate, the hazard associated with the liquid, proximity to town/city, containment capabilities and early awareness.
Does Space require a detailed analysis of every provision of API 2350?
Space does not permit a detailed analysis of every provision of API 2350. Conforming to API 2350 does require a detailed risk assessment of storage tanks and comparison to the standard’s recommendations. The following is an example of a high-level risk assessment.
What is the purpose of asking questions during an assessment?
During an assessment, the patient may be asked to reveal very personal and private information. It is important that you explain why you are asking these questions, and what you will do with the information that the patient gives you. For example, “I'm going to ask you some questions about your drug use.
Who should conduct a drug assessment?
The person conducting the assessment should be a healthcare worker – a doctor, nurse, psychologist or other person with a health-related qualification.
