Abstract
A system for dispensing fluid includes a reservoir chamber for receiving a liquid dose, said reservoir chamber in fluid flow connection with a liquid supply line via a first valve; a measuring chamber arranged in fluid flow connection with said reservoir chamber, said measuring chamber having a sensor for outputting a signal indicative of a volume of liquid in said measuring chamber; and a processor to control the operation of the first valve, based on the signal from the sensor. The system may also be used to determine liquid pressure in a liquid supply line and a volume flow rate of the liquid supply line.
Claims20
A system for dispensing a liquid dose into a liquid supply line, the system comprising:
- a reservoir chamber for receiving a liquid dose, said reservoir chamber in fluid flow connection with a liquid supply line via a first valve;
- a measuring chamber arranged in fluid flow connection with said reservoir chamber, said measuring chamber having a sensor for outputting a signal indicative of a volume of liquid in said measuring chamber;
- and
- a processor to control the operation of the first valve, based on the signal from the sensor.
A system for determining liquid pressure in a liquid supply line, the system comprising:
- a reservoir chamber in fluid flow connection with a liquid supply line via a valve;
- a measuring chamber arranged in fluid flow connection with said reservoir chamber, said measuring chamber having a sensor for generating a signal indicative of pressure in said measuring chamber;
- and
- a processor to selectably open the valve, and to receive a signal from the sensor corresponding to a change of pressure in said measuring chamber, thereby to determine the liquid pressure in the liquid supply line.
