Magnicator® with Guided Wave Radar (MGWR™)

Redundant Sensing Technologies for the Ultimate in Reliable Level Indication

By combining Guided Wave Radar (GWR) with a Magnetic Level Gage, the Magnicator Guided Wave Radar (MGWR) brings a new standard of assurance to level indication.

The primary advantage of a guided wave radar (GWR) transmitter over a Magnetostrictive or Reed Switch transmitter is that the GWR transmitter is an independent device that does not rely on the float’s magnetic field to obtain a reading.  A Magnetostrictive or Reed Switch transmitter measures the position of the float inside the magnetic gage, while the GWR transmitter detects the actual fluid level.

The GWR transmitter obtains an independent reading of the liquid level, providing an accurate output even in the case of a float failure.  Also, the GWR transmitter will read the true level of the fluid, even if the density of the product varies.  With a magnetic gage, the float is sized for the minimum specific gravity and the gage float position in the fluid will change with the specific gravity.
