Highest accuracy for loading viscous bitumen
GRISARD BITUMEN AG relies on Promass Q 500
GRISARD BITUMEN AG develops, refines and distributes bituminous adhesives of high quality. The standard bitumen delivered to BITUTANK AG by ship is refined with additives to make polymer-modified bitumen (PmB) and then transported to the customer by rail or tank car. To load tank cars, GRISARD BITUMEN AG uses a truck scale and the new Promass Q 500 Coriolis flowmeter. This flowmeter enables the bitumen, which sometimes outgasses, to be measured with unprecedented accuracy.

Proline Promass Q 500 (Swiss Technology Award winner) for accurately measuring fluids such as bitumen containing gas entrainments or microbubbles
The results
Measuring errors could be reduced from a maximum of 8% down to 0.1 to 0.2%
Greater plant availability thanks to web-based data handling
For years we have found Endress+Hauser to be a skilled and reliable partner. The very close and good cooperation with the service engineer was particularly decisive.

The customer's challenge
Previously, the amount of bitumen filled into the tank cars was determined using a truck scale and another type of Coriolis flowmeter. Due to the outgassing processes in highly viscous bitumen, however, this older Coriolis flowmeter showed measuring errors of up to 8% as compared to the truck scale. Since the flow measurement point is operated system-dependently on both the discharge side and intake side of a pump, outgassing processes are the norm due to pressure fluctuations.
Our solution
The bitumen application made it necessary to search for a flow measuring technology (i.e.
Proline Promass Q 500
In place of the original Coriolis flowmeter – which had provided flawless measurement results for bitumen that was not outgassing – a
