The invention relates to a method and an arrangement for measuring a fluid. Electromagnetic radiation is used to measure the consistency, flow and/or gas content of a fluid flowing in a process pipe ( ). At least two of the measurements are carried out substantially from the same measurement point in the fluid in a measuring tube ( ) by utilizing one integrated measuring equipment ( ) comprising transmitters and receivers for electromagnetic radiation in order to carry out the aforementioned at least two measurements.

Method and arrangement for measuring fluid

The invention relates to a method and a measuring arrangement for measuring the gas content of a fluid ( ). The fluid ( ) comprises gas bubbles. In the method, microwave radiation ( ) is transmitted through the fluid ( ) and a signal ( ) indicating the travel time, phase or amplitude of the radiation ( ) is formed in a microwave measuring device ( ), and a gas measuring equipment ( ) determines the gas content of the fluid ( ) by means of the signal ( ).
