Volumetric pump with a variable flow rateDURANDAU ROGER
I should write the UDF to calculate the volumetric flow, in different planes. In order for changing variable value of the source. Please help me! Sorry my bad english. January 26, 2015, 12:36 #9 Harry321 Member Join Date: Dec 2014 ...
A plurality of transducers are positioned in the walls of a pipe conveying a fluid, the volumetric flow rate of which is to be measured. Opposed upstream and downstream transducers project acoustic energy toward one another through the fluid, along a plurality of parallel paths. Electronic circuitr...
Variable area meters and turbine flow meters arevolumetric measurement devicesthat are prone to temperature or pressure variations. Additionalmass flow sensorsfor these parameters, as well as a flow computer to correct for fluctuations in these process conditions, would be required formass flow measureme...
This can be achieved with a constant volume flow system through fine tuning of the air control system. Through tolerances in the intake and outlet air quantities, with a variable volumetric flow system (VAV), a difference in the volumetric flow almost always occurs, which immediately causes a ...

The valve features two valve elements, each movable independently of the other, one sensing and responding to flow through one variable opening, and the other responding to and cooperating with the first in adjusting flow through a second variable opening, the first variable opening being in the ...
Contractility is difficult to quantify in the clinical setting because inotropy, preload, and afterload are interrelated in such a way that a change in one variable will simultaneously alter the others (see Figure 3-11).32,33 Put in more general terms, cardiac contractility is load dependent. ...
