Highest measuring accuracy when discharging bitumen
Grisard Bitumen AG relies on Coriolis flowmeter Promass Q with unique 4-tube technology
To attain the highest degree of measuring accuracy when unloading viscous standard bitumen from ships and boiler trucks, Grisard Bitumen AG at the Auhafen Muttenz port near Basel, Switzerland, relies on Proline Promass Q 300. The Coriolis measuring device is now available up to DN 250 (10") and provides a massive boost to the cost efficiency of the delivery process.

The result
Excellent measuring accuracy for fiscal metering
Reduced pressure loss thanks to revolutionary 4-tube measuring technology leads to cost-efficient unloading operations
Up to 25% higher flow rate in the same amount of time (for DN 150 to 250, 6 to 10")
"Promass Q from Endress+Hauser impresses with excellent measurement results, high freedom from maintenance and process reliability despite the highly viscous bitumen."

The challenge
The standard bitumens, which are delivered by ship or rail, are discharged at the terminal and pumped into three storage tanks via heated pipelines at +160 °C (320 °F). For billing purposes with the supplier, it is critical for the results at the unloading measuring point to be as exact as possible in order to reconcile these with the verification measurement.
Our solution
After Grisard Bitumen AG had already switched to Promass Q 500 DN 80 (3") at the loading station and had an excellent experience, the company took the opportunity provided by the construction of a new line to optimize its processes. Once again, Grisard Bitumen AG decided in favor of Promass Q, which is also available with the revolutionary 4-tube technology.
Grisard Bitumen AG has been successfully active in the Swiss bitumen market for 100 years. It develops, refines and distributes bituminous adhesives of high quality. In its own laboratories, it creates customer-specific bitumen for construction of roads and air-fields as well as for roof sheeting and building insulation materials.
