Flow Rate Totalizer Precision Digital’s flow rate/totalizers display the flow rate from either an analog or pulse output flowmeter as well as the accumulated total and grand total volume over time. Relay, open collector, and analog outputs combined with a variety of power options including AC,...
Flow rate is the volume of fluid that moves through a system over a given period of time. It’s a key measurement in fluid systems used in applications ranging from residential water lines to industrial processing plants. Knowing this value helps match your pump and piping to the task and k...
The volumetric flow rate in fluid dynamics and hydrometry, (also known as volume flow rate or rate of fluid flow) is the volume of fluid which passes through a given surface per unit time (for example cubic meters per second [m3 s-1] in SI uni...
In flow counting, however, the sample counting time is a function of the flow rate and flow-cell volume, as the sample consists of a stream which passes through a tube (flow cell) situated perpendicular to the faces of the photon detectors (PMTs) as illustrated in Fig. 12.2. The photon...
Therefore, the parameters of interest to the process engineering or the housing meters are the volume flow rate of the fluid, Q, defined as: (1)Q=uA where u is the average flow velocity, A is the cross-section area of the pipe. In practice, the velocity is not homogeneous in pipe, ...
This IV flow rate calculator (also an IV drip rate calculator) helps determine the correct drip rate of an intravenous fluid— based on the volume and time the medicine should be administered over that has been prescribed for the patient. You may have already noticed the abbreviation of intrave...
I have a pulsating flow at inlet of a device. I have calculated the mass flow rate (pulsating) by averaging it over time. The flow is going in. Now I want to calculate the volume flow rate. So I mass averaged the velocity over the inlet face. But the averaged velocity shows the opp...

The variation of flow rate over time under dynamic valve movement is primarily governed by the following mechanisms. At the beginning of valve movement, the water-saving valve has the highest outlet opening, the highest water output, and the highest flow rate. As inlet pressure acts on the val...
The first level of model considers a Poisson distribution with a time-varying rate parameter (λ) for the duration of floods. λ, the rate parameter is informed by a regression on the antecedent exceeding flow accumulations with intercept α and coefficient β for each reservoir r. The second...
