WebAug 10, 2024 · This webinar covers some of the basics of how flow is typically measured at an NPDES discharge point. The information is applicable to the discharge from wastewater treatment plants or from industrial dischargers. The webinar also covers guidance on how various open and closed channel flow measurement devices function, how they are … Flow measurement is the quantification of bulk fluid movement. ... References will be made to "actual" flow rate through a meter and "standard" or "base" flow rate through a meter with units such as acm/h (actual cubic meters per hour), sm 3 /sec (standard cubic meters per second), ... See more Flow measurement is the quantification of bulk fluid movement. Flow can be measured using devices called flowmeters in various ways. The common types of flowmeters with industrial applications are listed below: See more Both gas and liquid flow can be measured in physical quantities of kind volumetric or mass flow rates, with units such as liters per second or kilograms per second, respectively. These measurements are related by the material's density. The density of a liquid is … See more A positive displacement meter may be compared to a bucket and a stopwatch. The stopwatch is started when the flow starts and stopped … See more A "variable area meter" measures fluid flow by allowing the cross sectional area of the device to vary in response to the flow, causing some … See more A primary flow element is a device inserted into the flowing fluid that produces a physical property that can be accurately related to flow. For example, an orifice plate produces a pressure drop that is a function of the square of the volume rate of flow through the … See more There are several types of flowmeter that rely on Bernoulli's principle. The pressure is measured either by using laminar plates, an orifice, a nozzle, or a Venturi tube to create an … See more Optical flowmeters use light to determine flow rate. Small particles which accompany natural and industrial gases pass through two laser beams focused a short distance apart … See more
