Bitumen measurements under diffi cult conditions

Task

The special challenge of this application is the exact temperature of the heat-tracing, which must be adapted to the respective type of Bitumen used. The meters must be robust and temperature-stable, and should furthermore not affect the accuracy of probable custody transfer devices.

Solution

Coriolis Mass Flowmeters from Heinrichs Messtechnik

• Precise measurements, even with high temperature fluctuations
• Durable due to bigger wall thicknesses of measuring tubes
• Variable, stable tracing systems for various heating media
• up to DN 400 / 16" for media temperatures up to 260 °C
• Versions for custody transfer operation
• Maintenance easy due to open design of the devices
• Can be retrofitted

Application

The robust construction of our Coriolis devices allow usage in mobile plants or machinery, such as in a „HOT-RECYCLER“, which removes the tarmac and re-applies it with the addition of asphalt and bitumen. The hot recycling method is used solely for the rehabilitation of damaged asphalt surface courses. The hot recycler  processes the existing road pavement, improving it with virgin mix, if necessary.
