👉 In physics and engineering, a hemadynameter is a device used to measure the flow rate of fluids. It is typically used in industries like oil refining, gas processing, or in water treatment where the volume of liquid flowing through an effluent system needs to be measured accurately. The term "hemadynameter" comes from the Greek word "hemadron," which literally translates as a funnel or a receptacle for a liquid being transferred from one container to another.
