Propane / Butane Storage Tank Indicators
Pressurized fuel storage tanks such as propane and butane often present a bit of a problem when measuring the product level. A dip stick is not practical to measure contents in a pressurized tank.
Electronic devices tend to be expensive and require a power source. The most common technique is a sight glass, but these usually cover a short range and larger tanks sometime require up to three or more sight glasses.
All the associated plumbing and connections plus the glass seals and cracks make a lot of leaks inevitable. Frequently there will be no level measurement because of all these problems. The magnetic level indicator is an ideal solution to the problem.
It is visible from a great distance, requires no power but can be fitted with alarm switches or transmitters if 24 VDC power is available. It eliminates a troublesome source of leaks which are hazardous, costly and environmentally polluting.
In some areas the local environmental regulatory agency has determined that hydrocarbon emissions can be reduced by 4% in a gas processing plant by replacing sight glasses with magnetic level indicators.
