How to Connect the ABB LWT Series Guided Wave Radar Level Transmitter Remote Head

The ABB LWT Series Guided Wave Radar Level Transmitter uses radar frequencies, guided in a probe going into the tank or vessel, to provide continuous, reliable level measurement with high accuracy. LWT300 series instruments cover a wide range of applications. They can meet your needs for applications up to 204 °C (400 °F) and 207 bars (3000 psi). ABB LevelExpert technology concentrates over 20 years of industrial level measurement experience into an intelligent instrument made to accurately detect levels, even in the most demanding conditions.

Certain process conditions warrant the use of a remote head on the LWT300 instrument. Remote head instruments are also very useful for any reason where you might prefer or need to distance the head from the coupler (ease of access, floating roofs, etc.)

There are three main steps to installing a remote head instrument:

1. Installing the probe-coupler assembly in the vessel. See LWT Series Guided Wave Radar Level Transmitter user guide for instructions.
2. Installing the head on a support bracket in a remote location. See LWT Series Guided Wave Radar Level Transmitter user guide for instructions.
3. Connecting the probe-coupler assembly to the instrument head with the proper coaxial communication cable.

This video demonstrates step three, the actual cable and remote head connections.

Procedure:

• When connecting either end of the coaxial cable, we strongly suggest the use of a wrench or pliers.
• Connect one end of the coaxial cable to the bottom of the head-coupler adapter.
• The coaxial cable bend radius shall not be less than 150 mm (6 in).
• Connect the other end of the coaxial cable to the top of the coupler.
• Complete.

ABB LWT300 Series Guided Wave Radar Data Sheet

With fast and reliable settings, ABB's LWT300 series of instruments emphasizes measurement made easy. With its LevelExpert technology based on 20 years of experience, simply enter installation data and basic process conditions, and let LevelExpert do the rest: no echo mapping or baseline correction required.

Unlike traditional guided-wave radars that use device parameters requiring multiple adjustments, the LWT300 series of instruments does it for you. The instrument uses built-in intelligence to differentiate between the actual level and other false signals. It also keeps monitoring all these false signals while maintaining a reliable level reading. It is like having a level expert in each device.

Combination Magnetic Level Gauge and Liquid Level Transmitter

Process operations involving liquids contained in tanks and vessels invariably need instruments that provide information about the degree to which the tank is full....how much process liquid is in the tank. It is common to have a need for multiple signals or indicators, utilized in the process monitoring and control scheme for differing purposes. A continuous liquid level signal from a transmitter provides remote indication of remaining tank capacity or a measure of tank contents. Liquid level switches can be wired directly into other control circuits for safety or operational control of other machinery supplying or draining the tank. Local operators can benefit from a visual indication of tank liquid level to verify process step progress. Obtaining all this process related information from the tank can require numerous separate tank connections, fittings and space for service and maintenance access. A good solution is available.

K-Tek, an ABB brand, combines a guided wave radar transmitter and a magnetic level indicator into a single compact instrument with one set of tank connections. The instrument can be custom configured in a number of ways, with accessories that can be added to suit any application. Service valves, additional transmitters, level switches and more can be added to the instrument at the time of ordering to minimize first cost, installation time, potential leak points, fittings, piping, space requirements and more. The datasheet included below provides more detail on the available configuration options, but you should share your level measurement and control challenges with application experts for a knowledgeable recommendation. Combine your own process knowledge and experience with their product application expertise to develop an effective solution.

Radar Level Measurement

Radar is a means by which electromagnetic waves of short wavelength (microwaves) are used to detect the presence, distance and location of a remotely located object. While well known for its use in miltary and air traffic control applications, radar ranging technology is used in industrial processing to measure liquid and solids levels in containers of many types.

Condensed to a simple explanation, a radar level measurement instrument emits timed electromagnetic energy bursts, measuring the time interval from each burst emission to return. The emitter directs the microwaves toward the surface of the material to be measured. As the distance from the emitter to the material surface increases, so does the transit time of the wave on its round trip from emitter to media surface and back to a detector antenna. This transit time is proportional to the distance from the emitter to the media surface and can be used to calculate the media level.

Radar level transmitters can provide onboard processing of the raw signal, delivering a standard industrial process control signal which is scaled to a useful value range indicating percentage of tank fill, or some other useful representation of media level. It is necessary for the surface of the material to be measured to have properties which will reflect a sufficient amount of the radiation to allow a detection of the return signal. This is not problematical for most materials, but each application should be discussed with an instrumentation specialist to confirm suitability.

Radar level technology is utilized in a guided wave format, where the emitted energy travels down a tube extending into the medium, and non-contact configurations with the microwave emissions dispersing as they travel from the source antenna. Both types deliver excellent accuracy and have their specific application criteria where they may be preferred.

Properly selecting and applying level measurement instrumentation requires consideration of many operational and technological aspects of each process. Share your process measurement challenges with application specialists and leverage your own knowledge and experience with their product application expertise.

Combine Two Liquid Level Technologies Into One Instrument

Combination Guided Wave Radar Transmitter
and Magnetic Liquid Level Indicator

Tanks and vessels containing process liquids benefit from having two independent indications of liquid level. A local indicator with high visibility provides on-site personnel the information needed to confirm a tank fill level or coordinate other tasks. An electronic signal provides continuous liquid level information to process control operations and monitoring equipment.

K-Tek, a subsidiary of ABB, combines a guided wave radar transmitter and a magnetic level indicator into a single compact instrument, fulfilling the total requirement with one instrument, one set of tank connections.

The instrument can be configured in a number of ways, with accessories that can be added to suit any application. Details are provided by the data sheet included below.

Share your level measurement and control challenges with application experts, combining your process knowledge with their product application expertise to develop effective solutions at your facility.
