6005 STG
Accuracy

Continuous measurement
to an accuracy of +/- 0.7 mm

Application

Used on a wide variety of bulk liquid storage tanks

Integration

Industry standard output communications available

Servicing

Easy to understand,
simple to maintain

Meets API and is ATEX approved

True Multi-Measurement

In addition to level measurement, the 6005 STG can determine the interfaces between three liquids, specific gravity of these liquids and tank bottom. This allows the instrument to provide spot density measurements, profile the liquid density throughout the tank, or profile the stratified upper layer.

Proactive Safety Diagnostics

In the event of an abnormal measurement condition, the servo outputs a maximum level value to the local display and system software, thereby causing an alarm to warn your operators.

Communcations

Compatible Communications

Output signals include industry standard RS-485 (MODBUS), as well as popular tank gauging protocols, such as Mark Space, Whessoe and Enraf BPM. You are also able to connect a spot or average temperature probe directly to the instrument.

Industry Approval

As you would expect, the servo is FM, ATEX and CSA approved for use in hazardous areas, NMI approved for custody transfer applications and approved for use in a SIL 2 system for overfill protection.

Simplifying Maintenance

Small features make your operators' lives easier and safer; intelligent diagnostics provide advance warning of required maintenance, such as replacement of worn wire. Wetted parts are completely separated from the electronic circuit and the built in calibration window allows operators to ensure the correct position of the displacer before service work is underway.

Designed for Industry

The servo is suitable for atmospheric and high pressure applications up to a demanding 363 psi (2500 kPa, 25 bar). To make sure it fits your existing tank fittings, we have a wide variety of process connections to choose from.
