  • Publication number: 20190277278
    Abstract: A pump controller or control device for determining a through-flow quantity in a fluid delivery system, in which a fluid is delivered by a pump, the pump including an electromotor operated at a first speed when the electromotor is in operation and the through-flow quantity being determined from a measured motor power and the speed. A method of using the pump controller or control device includes (i) increasing the first speed to a second speed which is greater than the first speed; (ii) determining a second through-flow quantity at the second speed from the motor power and the second speed; (iii) determining a third through-flow quantity from the second through-flow quantity by extrapolation of the second speed to the first speed, wherein the third through-flow quantity is the target variable; and, (iv) reducing the speed back to the first speed once the second through-flow quantity has been determined.

  • Publication number: 20180328366
    Abstract: A feed pump to increase the pressure in a line includes a pumping chamber for a pumping medium. At least one temperature sensor, which is arranged in the feed pump, is allocated to the pumping chamber and is in thermal contact with the pumping chamber for determining a temperature of the pumping medium in the pumping chamber. A temperature control device is allocated to the at least one temperature sensor and by which defined temperature conditions can be created in an area surrounding the at least one temperature sensor. An evaluation device to which the at least one temperature sensor is coupled for signal purposes uses the data from the at least one temperature sensor to determine whether pumping medium is flowing through the pumping chamber or not.

  • Patent number: 4873828
    Abstract: A method and apparatus for storing excess electricity generated during off-peak periods. The electricity is used to run compressors which compress the air in a plurality of stages. The air is cooled after each stage to remove the heat of enthalpy. The air is stored in bags on the bottom of the sea. To recover the energy, the compressed air is run through turbines and the heat removed during compression is reintroduced.
