The TTB module performs a flow in forced conditions of depression of devices like throttle bodies and carburetors.
In particular, it’s interesting to know the minimum flow of these objects in conditions of strong bottlenecks (closed throttle), because in these conditions small changes in machining and assembly can produce big flow differences.
Pressing the START button the system starts up the compressor until the target flow or depression condition (selectable via software), and after that it performs the measurement after stabilization of values.
The flow and depression range impact on the choice of the compressor – usually max depression 600 mbar.
The test is automatically controlled by the software, which records and plots the overpressure and flow curves.
