Rummel FlowBasic: the basic model of electronic multi-circuit distribution
FlowBasic is a multi-circuit distribution system that distributes mold temperature control water to several separate circuits and measures flow and temperature electronically in every circuit. It is the entry model of the family: designed for cold and medium-temperature molds running on water up to 120 °C. Its stainless steel and brass body is compact and robust; each circuit is set separately with user-friendly ball valves.
What does it measure and record?
Flow and temperature are measured in every circuit; pressure measurement can be added as an option. The measured values are shown graphically on the visualization terminal with touchscreen. Process data are collected and evaluated, process parameters are documented and stored, and parameterization and status monitoring are done on the same screen. When limit values are reached, an alarm is triggered; the mold parameters are saved and recalled the next time the same mold is mounted.
Measuring principle
In FlowBasic the flow is measured with a vortex piezoceramic sensor element. The sensor has no moving parts. The measuring range is 1.0–20 L/min per circuit; this range covers the great majority of standard cooling water circuits with a single sensor type.
The circuits are controlled with manual shut-off ball valves. In other words, FlowBasic does not adjust the flow itself; it measures, displays and warns on deviation. If the flow should be adjusted automatically, look at the FlowCon model in the same family.
Contribution to mold temperature control
- With no hose bridges, pressure loss falls and the flow per circuit rises
- Heat transfer in the mold improves
- Because the circuits are separate, a faulty circuit is located precisely
- Specific zones of the mold can be adjusted individually
- Fouling in a circuit shows up as a drop in flow
- The alarm comes before scrap parts are produced
- Process stability and traceability increase
Installing the distributor close to the mold makes short hoses possible. The system is insensitive to pressure surges and can be extended step by step.
Modular design
The manifold is offered in extension stages of 2, 3, 4, 5, 6, 8, 10 and 12 stations and can be expanded to up to 100 circuits by cascade connection. It is possible to start with a small mold and grow the system as molds with more circuits arrive.

FlowBasic or FlowBasicHot?
The two models share the same software logic and the same modular design. If your mold temperature exceeds 120 °C or your system pressure is above 10 bar, the FlowBasicHot, which runs up to 160 °C and 15 bar, should be chosen. For screen and interface options, see the control unit and operator panel page.
