Level Measurement & Control


Level measurement is becoming more sophisticated

October 2018 Level Measurement & Control

Since radar was developed and deployed during WW II, its use has expanded enormously. As technology advances, these uses are also advancing. For example, radar technology is used in the motor industry to assist in detecting objects near a car or truck, for warning systems. Radar can also detect if a person has fallen overboard from a cruise ship, while the construction industry uses radar to test concrete viability and strength consistency.

When it comes to level measurement, radar offers accuracy and efficiency, which is essential for safety, stock inventory and processing. Radar is exceptionally robust and can be used in any weather or environmental conditions, as well as for nearly every temperature range and viscosity of the measured medium. Deon Rampathi, sales manager for Krohne, says, “Accurate, consistent measurement is essential and radar technology delivers just that.”

Applications are becoming smarter

The world is becoming ‘smarter’ and solutions need to fit into applications that have become increasingly tech-savvy, as well as more automated. Smarter measurement enhances the safety, sustainability and efficiency of operations. This extends into more reliable and enhanced up-time as well as the extension of equipment service life.

“We’ve introduced the Optiwave 7500, a powerful radar measurement tool that is geared towards those hard-to-reach situations,” adds Rampathi. “It’s a new generation of liquid measurement with better performance, enhanced software and a more powerful signal processor.”

The Optiwave 7500 has an 80 GHz FMCW radar level transmitter to handle liquids in narrow tanks with internal obstructions. The flush-mounted Peek Lens antenna means there is no tank intrusion. It is also insensitive to deposits and has a small dead zone and beam angle (4°) with flange plate protection for corrosive media and a 112 mm antenna extension for long nozzles. Accuracy is 2 mm and there is an extensive choice of process connections with measuring distances up to 100 m at temperatures up to 1500°C.

“For our customers who want to keep their existing antennae and upgrade the electronics without losing the hermetic seal on the tank, there is an Optiwave 7500 retrofit option,” concludes Rampathi.
