| 3. | | • | Types of flow devices | | • | Selecting a flow device | | • | Basics of installation |
| 00:01:04 |
| 4. | | • | Positive displacement | | • | Differential pressure | | • | Mechanical volumetric | | • | Magnetic | | • | Ultrasonic | | • | Thermal | | • | Fluidic | | • | Mass flow | | • | Open Channel |
| 00:01:16 |
| 5. | | • | Operate by permitting a known volume of fluid to pass through the meter | | • | Highly accurate (typically 1-1/2% of rate or better) | | • | Handle higher viscosity materials (even up to 20,000 centipoise) |
| 00:01:29 |
| 6. | | • | Operate by sensing the differential across an orifice or flow restriction…the flow rate is proportional to the square root of the differential. This is an example of an advanced differential pressure meter. |
| 00:01:47 |
| 7. | | • | Operate by converting rotational speed of a rotor (such as a turbine) to turn a gear train or produce an electronic pulse | | • | Accuracies vary from 5% of span to 1-1/2% of rate |
| 00:02:09 |
| 8. | | • | Operate by Faraday’s law…the most inherently accurate volumetric flow meter | | • | Available in flanged, wafer, and insertion styles, and also available for partially filled pipes |
| 00:02:35 |
| 9. | | • | Operate by either measuring the transit time between two sensors or the doppler shift caused by the velocity of the solids-bearing liquid | | • | Usually supplied as clamp-on devices |
| 00:03:09 |
| 10. | | • | Operates by measuring the thermal dispersion caused by a moving fluid flowing past a heated temperature sensor | | • | Excellent for use as a flow switch, usually about 5% accuracy |
| 00:03:24 |
| 11. | | • | Operate by forcing the fluid to oscillate in a detectable fashion | | • | most common types are vortex shedding, the Swirlmeter™, and the various Coanda-effect flow meters |
| 00:03:48 |
| 12. | | • | Mass flow meters for liquids are generally coriolis based instruments | | • | Gas mass flow is usually done by thermal dispersion | | • | These meters read mass directly, and flow and density can be deduced. |
| 00:04:21 |
| 13. | | • | Operate by measuring the head height behind a flow restriction (flume or weir) | | • | Sensors can be floats, ultrasonic level sensors, ultrasonic uplooking sensors, and other types |
