The level measurement market in Canada has seen considerable growth in the usage of radar level devices. One type of radar level device is known as “non contact” or "through air radar". These devices use, and emit, very low levels of microwave energy. A small fraction of what a cell phone emits.
However as these devices are “intentional radiators” they fall under the review of Industry Canada, and the FCC in the United States. These government bodies use the term “ "Tank Level Probing Radar" (TLPR) for these devices. They are required to ensure that these devices will not interfere with any other devices. The traditional approach in Canada has been to require these devices be installed inside a vessel that would help contain this small amount of microwave energy.
A Lower Price Is Never The Answer
We are all very aware of initiatives to potentially achieve savings and improve our bottom line results. In many cases, the perception is that a lower price will result in savings; this is not the case in the area of filtration. Consider one filter with a unit cost of $15 verses another at $30, yet the filter costing $30 provides superior performance results to that of the $15 filter. This performance could be realized in terms of:
- Improved retention/removal of debris (contaminant) in the process flow stream.
- Increased throughput (volume filtered) or a safety benefit of operator exposure by reducing the number of filter changes.
- The cost of filtration operation.
Be an informed player by getting the resources you need to take on the challenge of compliance. Manufacturers of equipment for use in hazardous locations and potentially explosive environments face an increasingly dizzying array of new standards, design requirements, regulations and ultimately customer requirements. With an ever-changing list of technical and commercial criteria, demonstrating compliance is rarely an easy task – even with what appears to be the most minor of changes. However, timely planning and preparation will take away some of the complexity. Some steps to consider that will expedite the process are:
