Abstract: A method and a high-pressure system for determining a flow control variable of a fluid flow flowing through a high-pressure-side high-pressure pump outlet of a high-pressure pump are provided. An externally arranged ultrasonic measuring device measures a flow speed of a fluid flow flowing through a pipe of the high-pressure-side high-pressure pump outlet. A use of an ultrasonic measuring device is provided for determining a flow value to be achieved of a fluid flow flowing through a thick-walled pipe. The ultrasonic measuring device is arranged on the outside on the thick-walled pipe of the high-pressure pump outlet. The pipe has a ratio of the internal diameter to the external diameter of 1:1.5 to 1:5. The ultrasonic measuring device dynamically measures the flow speed of the fluid flow and transmits this measured flow speed to an evaluation unit to compute a current flow value and the flow control variable.

Abstract: A method and system for monitoring fluid flow in an open channel system, using an optical fibre that extends along at least a portion of the open channel system within the channel below the surface of the fluid. The method comprising sending light pulses into the sensor optical fibre, receiving backscattered light from the sensor optical fibre, and analysing properties of the backscattered light to obtain data representing strain along the sensor fibre. The strain data can be processed to derive information about the fluid flow, such as fluid depth, flow velocity and flow volume. A containment system for the optical fibre sensor may be included to protect the fibre and convert the pressure of a fluid in the open channel to a strain in the fibre. The temperature of the fluid may also be measured and temperature compensation of the measured strain carried out. The system is particularly applicable to sewers, drains, culverts or levees, with the optical fibre sensor installed axially at the bottom of the channel.
