The Jerguson FlashProof design addresses two potential problems that may occur with standard level indicators: boiling fluids and flashing vapors. By employing a larger 3″ Schedule 40 pipe and two internal guide rods, entrained gases that build up under the float can harmlessly escape. The float is held to one side of the chamber to insure an optimized magnetic field in close proximity to the indicator, transmitter or switches. This provides an accurate float level and indicator reading.
The Jerguson FlashProof design also addresses problems caused by dirty or viscous services. The use of an oversized 3″ Schedule 40 chamber creates additional space to prevent the float from binding when dirt, sludge, or wax-like solids are present in the process fluid. In a standard gage dirty service could potentially bind the float, causing the level to appear unchanged. Additionally, the bypass zone allows for the gage to be flushed without removing the float from the column.
