The aluminum liquid level gage is a durable and cost effective instrument for monitoring the liquid contents of reservoirs.  These black and red anodized versions are engraved with high and low level marks.  An aluminum ball inside the glass sight floats on top the liquid and provides an additional visual cue for clear fluids and/or poorly lit areas.  These gages are an example of how Oil-Rite equipment can be adapted to specific applications and customer requests.  View a detailed product description of each gage here and here.
