Mainstream IV Portable
Mainstream uses the area-velocity method to give a continuous or time sampled measurement of fluid flow. Suitable for any liquid containing bubbles or suspended solids, even in minute quantities, the velocity probe detects reflected ultrasound.
Signals from the probe are analysed using Phase Coherence Processing (patents pending). Phase Coherence Processing only accepts signals containing verified velocity information. The percentage of signal accepted is the signal quality.
A high signal quality confirms the integrity of the measurement. The verified velocity signals produce a histogram of the flow velocities. Analysing this histogram gives the mean flow velocity.
The liquid level is measured by a submerged pressure transmitter or ultrasonic sensor.
Flow cross-sectional area is deduced from the liquid level measurement and a stored description of the pipe or channel cross-section.
The flow velocity is multiplied by the flow cross-sectional area to give the flow rate and integrated to give the total discharge.
