  • Attenuation of an ultrasonic beam by suspended particles and range of acoustic flow meters in sewer networks

    Ultrasonic flow meters are commonly used in wastewater management. Under certain circumstances, a reduction in the flow meter range may occur and cause significant error in the flow rate measurement. Attenuation due to suspended particles is one of the phenomena capable of reducing the flow meter range. The present paper examines attenuation resulting from re-suspended pond sediment over a wide ...

  • How Does a Water Flow Meter Work?

    A water flow meter works by measuring the amount of water that passes though the flow meter. The most common mechanical types work by measuring the speed of flowing water that causes a turbine or piston to rotate. The volumetric flow rate of the water is proportional to the rotational speed. Other water flow meters include ultrasonic, magnetic and vortex flow meters. The best type of water flow ...
