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.
