Electronic level sensor detects changes in buoyancy

The Total Tank Level Measurement System (photo) incorporates magnetostrictive sensing technology and multivariable functionality. The system’s digital Modbus output measures total level, interface level and temperature from an explosion-proof housing. The system features five temperature-sensor outputs, distributed over the active length of the system’s polymer and stainless-steel probe. The rugged and flexible probe is available in lengths up to 50 ft. It is also available in a rigid Type 316 stainless steel version. The system’s intrinsically safe, explosion-proof design and all-welded construction makes it suitable for use in oil-and-gas, chemical and petrochemical storage tank and inventory-control applications, says the company. It has an accuracy of 0.01% of measured span (less than 1 mm absolute), over the full measurement range. It meets FM and FMc hazardous-area approvals and requires minimal maintenance. — Ametek Drexelbrook, Horsham, Pa.
