Maintenance Prediction
Servo tank gauge will provide advance warning of required maintenance, such as replacement of worn wire, etc. The operating life span of electrical and mechanical parts of the servo tank gauge are factory set within the instruments memory. This information is checked with the built‐ in clock and then compared, and registered in the instrument.
Automatic Displacer Weight Compensation
The displacer can be checked for buildup or corrosion by comparing the measured weight of the displacer in the air with the pre‐ programmed displacer weight.
The servo tank gauge can be set to perform periodical checks for the displacer weight; any deviations in the weight will then be corrected and an alarm or memo initiated.
Automatic Compensation of Wire Length
When the displaceris moved from the level position to the reference point(mechanicalstop within the instrument),the calibration can be checked. If there is any deviation outside the tolerance, the instrument will emit an alarm. If the deviation is within the tolerance (set by the customer), an automatic recalibration will be done. This function can be working manually or automatically in pre‐set time intervals.
