Guided wave radar is a critical instrument used in measuring levels, especially in processing plants. It is ideal because it remains unchanged by conditions such as temperature, vacuum, and pressure in the processing plant. It’s also not affected by the viscosity, density, and conductivity of the products it is measuring whether solids, liquids, or vapor. Although it is simple to use, different features enhance its efficiency. Here are the factors you need to consider when buying guided wave radar to ensure that you get optimal results.
Performance of the Signal
This is one of the most important features for an efficiently guided wave radar. Although you need to pay attention to the amplitude of the pulse transmitted by the radar, pay more attention to the radar’s signal to noise ratio. The best guided wave radar level should have features which reduce the radar’s noise impact. Thus, it increases the overall performance of the signal transmission.
Seek advice from an expert before you go shopping for one especially if it’s your first time. This will help you understand the process parameters you need and what to look for in one. This can save you the cost you would incur upon frustrations of buying an ineffective radar for your processing. Some manufacturers will agree to pre-configure the radar before supplying it to you This saves you the time and money you would have otherwise spent to install the radar. Research and order from a manufacturer who does not charge for this service.
Types of Probes Used
The types of probes used in a guided wave radar affect the effectiveness of the radar, especially in complex processes. Choose a radar whose transmitter has a line dedicated to probes. Avoid guided wave radars with a transition point at their top. This is because the interaction of the signals at the transition point can cause signal loss or even affect measurements’ linearity making causing errors. Look for a radar which comes with probes which are safe from overfill. This ensures that the whole wavelength is uniform and predictable, leaving little room for GUM.
Ensure that the radar you buy whose transmitter comes with advanced technological features for diagnosis. These features include the ability and ease of saving the echo curve and diagnostic features which can store information based on time and the specific events, for instance, the absence and strength of the echo. With these features, the transmitter records these curves in its memory for ease of future reference and diagnosis.
A good radar should be easy to install and disconnect as this saves you time and energy. Some radar transmitters are mounted on the probe directly while others have the option or being mounted remotely at about three and a half meters from the probe. It is best for you to choose the latter because it makes it easy for experts to view. It is also ideal if you are dealing with high-pressure processing plants.
With this guide, you will definitely get the ideal guided wave radar for your needs.
