FL 03.1i – Computerized Series and Parallel Pumps
With this equipment you can practice much of the operations, start-up, operation and necessary regulations in a pump installation.
The two pumps that the equipment has are controlled by a frecuency variator, which allows varying the speed of rotation. One of the pumps has a mechanical torque measurement system.
The flow rate of each pump is measured by an electronic flow meter.
In addition, you can make an study of the characteristics of a pump, working individually and in groups, in series or in parallel, performing a wide range of practices and experiences.
The whole system is controlled by a computer with touch screen (included), from where the pumps can be swiched on or off, or change the turning direction of one (the one which has the torque measurement system).
Moreover, the software allows the recording of data manual or automatically, and show the results into graphs.
