First developed during WWII, practi- cal radar instrumentation has grown to include a myriad of sensors and transmitters. Today, radar serves us in applications that range from the commonplace to the cosmic.

But radar’s beginnings were less than auspicious. Equivalent Time Sampling (ETS) measures the high Early level instruments were costly, bulky, over-specialspeed, low power electromagnetic energy (EM). ETS is ized and complicated.

ETS captures the EM signals in TYPES. Radar level sensing devices detect the real time (nanoseconds) and reconstructs them in position of process liquids by measuring the interval equivalent time (milliseconds), which is much easier to between the emission and return of high frequency measure with today’s technology. radio waves.

Radar applications are influenced trajectory directed toward the process media. by three basic conditions: (1) the Dielectric of the PULSE RADAR. Of the two operational technoloprocess medium; (2) the Distance, or measuring range gies commonly used for radar, Magnetrol products employ a pulse burst approach rather than frequency modulated continuous wave (FMCW). Pulse Burst Radar operates in the time domain and does not require 500 ns complex and expensive processing as needed to 1 ns enable FMCW. Because echoes are discrete and separated in time, Pulse Burst Radar is better able to sort through extraneous echoes and select the one generated by true level. Pulse Burst Radar also has excellent averaging characteristics, important in those applications where a return signal is attenuated by the factors described below. Unlike true pulse devices that transmit a single, sharp (fast rise-time) waveform of wide-band energy, Magnetrol products emit short bursts of 5.8/6.3 GHz (Pulsar) or 26 GHz (Model R82) energy and measures the transit time of the signal reflected from the liquid surface. Distance is calculated utilizing the equation: 3 of the application; and (3) a variety of Disturbances that attenuate or distort the radar signal. The Distance, or measurement range, is a function of the instrument’s frequency and selected antenna, the dielectric constant of the media, and the presence of signal interference. Disturbances caused by turbulence, foam, false targets (interior tank obstructions causing false echoes), multiple reflections (reflections from off the tank roof), or a high rate of level change, can weaken, scatter or multiply radar signals. Very high and very low liquid levels can also be problematic. SIGNAL PROCESSING. Radar’s signal processing function is critically important because radar exhibits interference effects similar to those that affect light. It is the quality of a device’s signal processing that separates today’s leading-edge radar transmitters from the others. Most disturbances mentioned above can be readily managed by Pulsar and Model R82 signal processing capabilities where true level can be extracted from false targets and other background noise. Using extremely energy-efficient circuits, no duty cycling is necessary to accomplish effective measurement. For this reason, Magnetrol’s Pulse Burst Radar products can also track high rates of change that have been impossible with other loop-powered radar transmitters. Although these products feature powerful False Target Recognition and Rejection routines, minimizing false target reflections is significantly affected by proper installation and orientation. ANTENNAS. The transmitter’s antenna transmits and receives the radar signal. Pulsar offers dielectric rod and horn types while the Model R82 uses an encapsulated horn antenna. Maximum measuring range of the instruments is chiefly dependent upon the instrument’s capabilities, dielectric constants, and the degree of turbulence. Dielectric constant, temperature, and pressure capabilities for our radar products are shown on page 6. INSTALLATION. A Quick Start installation procedure provides the key steps for mounting, wiring and configuring Magnetrol transmitters. Though transmitters come configured from the factory, they can be reconfigured in the shop. Bench configuration provides a convenient and efficient way to set up the transmitter before going to the tank site to complete the installation. The transmitter is password protected to protect configuration values. A HART® remote unit, such as a HART communicator, can be used to provide a communication link to the Pulsar and R82 transmitters. When connected to the control loop, the measurement readings shown on the transmitter will be shown on the communicator. The 4 communicator can also be used to configure and troubleshoot the transmitter. See page 11 for information on PACTware, today’s leading configuration and diagnostics software. BENEFITS. Magnetrol Radar products are engineered to measure a large number of liquid media in a broad range of process conditions, from calm product surfaces and water-based media to turbulent surfaces and aggressive hydrocarbon media. As a non-contact device, these products are not susceptible to the complications that arise whenever a probe contacts the process media, such as coating by viscous media or corrosive attack due to aggressive chemicals. The greater the measuring range, the more does radar prove itself to be the economical solution, given the cost of extended probe lengths. Radar is virtually unaffected by the presence of vapors, or air movement within a vessel’s free space. Changes in specific gravity, conductivity and dielectric constants also have no effect on measurement accuracy. As a 100% electronic instrument, the absence of moving parts translates into low maintenance costs. As a twowire, loop-powered device, power requirements and installation are greatly simplified.

With your PC connected through a serial interface to the HART loop, all functionality can be managed remotely anywhere on the loop. Level Monitoring Screen Continuously viewing the level in a tank is the starting point for PACTware. The position of liquid level can be viewed in a simple visual format on your PC. Level and Output values are shown numerically as well. The screen can be left open to show the relative position of the liquid level. Level Monitoring Screen Parameters Screen Every parameter in your radar transmitter can be monitored and modified remotely with a few clicks of the mouse. From units of measure to settings for dielectric, each parameter can be viewed or changed to suit application conditions. Parameters can be developed offline or transferred between transmitters. Trending Screen The ability to trend data over a period of time allows insight into overall operation of your radar. Trending values are invaluable when attempting advanced configuration or troubleshooting. PACTware PC software has the ability to track all parameters of your radar device and save them as a text or picture file. Echo Wave Form Screen This screen yields a wealth of useful information: Level (X-axis), Signal Quality (Y-axis), Actual Echo Curve (black line), False Target Profile (red line), and Minimum Threshold (blue line). Blue hash marks show the location and signal quality of the target currently detected as liquid level. False Target Rejection—a GET CONNECTED Simply connect the HART/RS232 or HART/USB serial interface from the PC to the two-wire loop. Process Trend Screen Parameters Screen common issue among all non-contact, transit-time devices—can be accessed from this screen.
