• Pennine Automation (PAL) had the answer when Leedsbased Drum Instrumentation needed a precision control sys tern for the calibration of its electronic liquid level indicators. It was the Drumstic, a liquid mass measuring system, which works by monitoring the change in resonant frequency of a rod immersed in the fluid/ fuel, petrol or diesel.
With this indicator, tankers can be loaded to their maximum legal capacity without fear of overloading, while the elimination of catwalks and ladders increases the payload. Each unit is individually calibrated by immersion.
The drive and control system which Drum originally installed proved inadequate generating intermittent calibration errors, producing "dirty" signals which crashed the controlling computer and starting up spontaneously. The replacement PAL system can be left to complete its operations unattended once the calibration program has been initiated.
Drum Instrumentation reckons it has replaced one of the oldest, simplest but most readily abused measuring devices by the only field-proven, gravity-independent mass measuring system in the world.
