When preparing bitumen solutions used in asphalt production, there is a need for dosing special additives to the bitumen.

A single dose of the additive can range from 20 to 80 liters, depending on the concentration of the additive itself and the grade of the bitumen.

For small-scale productions, this task can be handled by a barrel pump with the use of a flow meter.

or a measuring container (a more cost-effective option)

For large enterprises, it is possible to implement a dosing scheme based on stainless steel vortex pumps from the company ROVER.

Using a flow meter with a control signal that will automatically shut off the pump when a certain flow rate is reached.

Or using the same pump in combination with a timer relay.
