Abstract
A mechanism for determining an intended flow rate of fluid pumped by a pumping arrangement for an agricultural vehicle. A processing system processes a set of parameters to produce the intended flow rate of fluid. The set of parameters comprises a measured pressure of the fluid, a duty cycle of the pumping arrangement and an indicator of a size of an orifice through which the fluid exits the pumping arrangement.
Claims15
A system for predicting an intended flowrate of a flow of fluid pumped by a pumping arrangement through an orifice, the system comprising:
- a pressure sensor configured to measure a pressure of the flow of fluid to produce a measured pressure;
- a duty cycle measurement system configured to measure a duty cycle of the pumping arrangement, when producing the flow of fluid, to produce a measured duty cycle;
- an input interface configured to receive an orifice size indicator, indicating a size of the orifice;
- and
- a processing arrangement configured to process the measured pressure, the measured duty cycle and the orifice size indicator to predict the intended flowrate of the flow of fluid.
A computer-implemented method for predicting an intended flowrate of a flow of fluid pumped by a pumping arrangement through an orifice, the computer-implemented method comprising:
- measuring, using a pressure sensor, a pressure of the flow of fluid to produce a measured pressure;
- measuring, using a duty cycle measurement system, a duty cycle of the pumping arrangement when producing the flow of fluid to produce a measured duty cycle;
- receiving, via an input interface, an orifice size indicator indicating a size of the orifice;
- and
- processing the measured pressure, the measured duty cycle and the orifice size indicator to predict the intended flowrate of the flow of fluid.
