Radar level gauge 2

Saab makes great ones. What service? Some services are more difficult than others or are best suited to different radar gauge technologies.

Thanks TD2K. The gauge is for a hazardous waste tank. I am on the Saab website right now. Which features are most important when selecting the right gauge?

Is the material a single phase liquid or susceptible to foaming? Are fumes or other vapors produced that could affect the accuracy of the unit? Hazardous waste covers a pretty wide range of materials.

Most of the magnetic level gauge manufacturers like Magnetrol and others offer guided wave radar as an attached feature for use as a level transmitter. Ohmart Vega offer open and guided wave radar level transmitters. These are very competitive with Rosemount Emerson Process Saab etc. Some require external power; some work from the 24 Vdc associated with the 4-20 mA signal power. Open radar includes cones and rods with associated issues related to the vessel design.

Watch for material compatibility with both the metalurgy and soft goods that contact the fluid.

Also consider magnetostrictive level instruments if dealing with light hydrocarbons with a dielectric constant too low to use radar.

I agree with John on the general aspects of guided wave radars - you should however be aware that the guided wave is NOT "touch-free" as a "normal" radar is.

Enraf also makes a good product.

As always, be sure to check their appovals, certifications, etc. to ensure if meets your requirements.

L & J Technologes alos makes a great Radar gauge along with technical support to select the proper unit. Go to

Also try Endress & Hausser for any type level application.

Drexelbrook also.....

Ashereng,
Do you mean Enraf also have radar level gauge? Please advise me.

PAN,

Yes, Enraf has radar level guage.
