We still often struggle with doing the dishes, and sometimes we just want our dirty dishes to magically disappear. If you do not have a dishwasher yet, you will definitely recognize this problem. However, manufacturers do their utmost best to make dishwashing as colourful as possible. You have probably noticed the large variety of detergents in your supermarket, so many choices! Mass flow controllers play an important role in the production process of these detergents. Let me explain why…
The unique method of combining your pump with a Coriolis mass flow controller makes the pump dose mass flow instead of the usual volume flow. Since real mass flow is independent of the fluid properties of the colourant, the accuracy will be inimitable.
A PID controller makes it possible to control the speed of your pump. This can be done by an external PID controller (however, this can result in a slow response and slow control) or by a Coriolis instrument with integrated PID controller (a separate control signal will control the speed of the pump).

Bronkhorst has a Coriolis instrument in its portfolio with integrated PID controller. The advantage of using a Coriolis instrument with integrated PID controller is the so called ‘closed loop system’. The flow will be immediately corrected if there is a change in back pressure by making the pump run faster or slower almost instantly, keeping up the required accuracy.
Additional benefit of this stable control method is that the pump is made to run on a moderate speed, decreasing wear and thus increasing its service life, resulting in less downtime of production equipment. Dosing mass flow instead of volumetric flow means high accuracy, for all your available liquids.
Other applications where you can encounter these challenges with dosing colourants/dyes are in production processes of shampoos, soaps, fabric conditioner agents, (shaving) creams and tooth pastes.
In a previous blog, I shared my thoughts about how pump control can optimize our detergent colour.
