  • How an Ultrasonic Flow Meter Works

    An ultrasonic flow meter utilizes ultrasound to measure the velocity of a fluid and is used in a variety of fluid applications. Ultrasonic flowmeters are ideal for water and other liquids. Clamp-on ultrasonic flow meters achieve high accuracy at low and high flows, save time with no pipe cutting or process shutdown, and are not affected by external noise. Here’s how ultrasonic flow ...

  • How Does a Water Flow Meter Work?

    A flow meter works by measuring the amount of a gas, liquid or steam that passes through or around the flow meter sensors. While flow meter sensors work in many different ways, the end goal is the same: Deliver the most accurate and repeatable flow measurements for the specific application, whether for general research, process control or semiconductor processing. Flow meters measure either mass ...

  • 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 ...

  • Assessment on inflow and infiltration in sewerage systems of Kuantan, Pahang

    Inflow and infiltration are important aspects of sewerage systems that need to be considered during the design stage and constantly monitored once the sewerage system is in operation. The aim of this research is to analyse the relationship of rainfall as well as inflow infiltration with sewage flow patterns through data collected from fieldwork. Three sewer pipelines were selected at the ...
