Total Tank Level Measurement System includes dual 4-20mA and Hart outputs in addition to the standard Modbus protocol for measuring total level, interface level and temperature.

Ametek Drexelbrook enhances the communication capabilities of its Total Tank Level Measurement System to include dual 4-20mA and Hart outputs in addition to the standard Modbus protocol for measuring total level, interface level and temperature. The rugged and versatile level measurement system is an alternative to flexible stainless steel cable probes. It incorporates magnetostrictive sensing technology and features multi-variable functionality. The system is reportedly accurate to 0.01% of measured span – less than 1mm absolute – over the full measurement range. 

The system’s intrinsically safe, explosion-proof design and all-welded construction make it a suitable choice for oil and gas, chemical and petrochemical storage tank and inventory control applications. Its five temperature sensors are evenly distributed over the active length of the polymer or stainless steel probe. The probe is available in a rigid 316 stainless steel version and in flexible PVDF in lengths up to 50 feet, an industry exclusive, according to the company.

The system meets FM, FMc, ATEX and IECEX hazardous area approvals and requires minimal maintenance. A variety of floats and mounting accessories are available. The probes are offered with a choice of mounting configurations.
