Fluid Flow

Fluid Flow

Fluid flow is the quantification of bulk fluid movement, which is important to many discovery, evaluative and monitoring studies, and can be measured in a variety of methods.

Signal Overview

Fluids are substances in a state that continually changes shape (flow) when force or pressure is applied, and are often synonymous with liquids, although fluids can also be plasmas or gases. Thus, fluid flow measurement is the quantification of its bulk movement and is important to many discovery, evaluative and monitoring studies. Furthermore, a wide variety of methods are available to measure fluid flow, where the suitability of each method depends on the nature of the fluid and aim of the study. A few are listed below.

Pressure Based Flow Measurement
These methods are based on Bernoulli's principle and they either measure the differential pressure within a constriction, or measure the static and stagnation pressures to derive the dynamic pressure, would directly indicate changes in fluid flow.

Ultrasound Transit-time Measurement
Liquid flow measurements can be made by using wide beam ultrasonic illumination and measuring the difference between the transit times of ultrasonic pulses propagating in and against the direction of flow. This difference in the integrated transit times is a measure of true volume flow.

Laser Doppler Flow Measurement
This method focuses a beam of laser light into an area of flowing fluid containing small particles (naturally occurring or induced). The particles will scatter the light with wavelength changes, which are proportional to the particle's speed (Doppler effect), and its quantification can be used to directly to determine the speed of the particle, and thus closely approximate the fluid velocity.

Enabling Discovery

LabChart

All your Fluid Flow analysis in one place

LabChart software is designed specifically for life science data and provides up to 32 channels for data display and analysis options that are powerful and easy to use. With auto-recognition of ADI and LabChart Compatible hardware, multi-window views, one touch recording, simultaneous recording from multiple devices, specialized preconfigured settings, easy sharing options and an interface that can be customized to show only the features you want to use.

Automating the Detection of Thresholds

Manually detecting when the fluid flow signal reaches a certain threshold can be tedious or inaccurate due to variability in reaction times. To help with this, LabChart has graphical aids such as Guide Lines and the DVM mini window, and the Event Manager Add-On to automate this type of detection. Event Manager continuously monitors the level of the signal in real-time and can automatically start a series of actions when a set threshold is reached, which includes either prompting the user or running a pre-programmed event script.
