Positive Displacement Flow Meter

A Positive Displacement Meter is a type of Flow Meter that requires the fluid being measured to mechanically displace components in the meter in order for any fluid flow to occur. Positive displacement (PD) flow meters make volumetric flow measurements taking finite increments or volumes of the fluid. A basic analogy would be holding a bucket below a tap, filling it to a set level, then quickly replacing it with another bucket and timing the rate at which the buckets are filled (or the total number of buckets for the "totalised" flow). With appropriate pressure and temperature compensation, the mass flow rate can be accurately determined.

Positive displacement flow meters are very accurate and have high turndown. They can be used in very viscous, dirty and corrosive fluids and essentially require no straight runs of pipe for fluid flow stream conditioning. They are widely used in custody transfer of oils and liquid fluids (gasoline) and are applied on residential home natural gas and water metering. A diaphragm meter, with which most homes are equipped, is an example of a positive displacement meter. This type of meter is appealing in certain custody transfer flow applications where it is critical that the metering be functional in order for any flow to take place.

PD flow meters are relatively expensive and produce the highest differential pressure (and subsequently greatest pressure drop head loss) of all the flow meter types.

Positive displacement flow meters measure the volume or flow rate of a moving fluid or gas by dividing the media into fixed, metered volumes. These devices consist of a chamber that obstructs the media flow and a rotating or reciprocating mechanism that allows the passage of fixed-volume amounts. The number of parcels that pass through the chamber determines the media volume. The rate of revolution or reciprocation determines the flow rate. There are two basic types of positive displacement flow meters. Sensor-only systems or transducers are switch-like devices that provide outputs for processors, controllers, or data acquisition systems. Complete sensor systems provide additional capabilities such as an integral display and/or user interface. For both types of positive displacement flow meters, performance specifications include operating pressure, temperature range, maximum material density, connection size, and percent accuracy. Suppliers indicate whether devices are designed to move fluid or gas.

The Measure of the World $3.95 On June 24, 1792, two large traveling coaches left the Tuileries, one for Dunkirk and the other for Barcelona. Their passengers, Pierre Mechain and Jean-Baptiste Delambre, were astronomers charged by the French Revolutionary government with the task of measuring the meridian that passes through these two cities in order to devise one universal unit of measure, "for all time and for all men," the meter. "The Measure of the World" by Denis Guedj tells the story of this strange and wonderful effort. Not a traditional history of science, the book is a novelistic account of the measurement project that relies heavily on archival sources. A more "traditional" history could not possibly describe how a sober scientific enterprise could turn into a journey filled with adventures and experiences so bizarre as to be hardly credible. In the tumultuous days of revolutionary and postrevolutionary France, Mechain and Delambre were objects of suspicion as they traveled through the provinces, climbing steeples and deploying strange instrumentsthey were detained as spies, taken for charlatans or fleeing royalists, and arrested for debt. Their perilous labors lasted until 1799, when the meter was formally established. Arthur Goldhammer's crisp translation of this wonderful novel retains the flavor of the original, and an appendix explaining Guedj's use of historical materials is included. A vivid re-creation of a fascinating and troubling period in history juxtaposed with the achievement of a complicated scientific undertaking, "The Measure of the World" is a marvelous book-not science fiction, but fiction about science. Denis Guedj is the author of "La evolution des savants" and "L'Empire des nombres," among other books. "La Mesure du monde" was awarded the Prix d'Institut in 1989. Arthur Goldhammer is an award-winning translator who has translated works by Emmanuel Le Roy Ladurie, Jacques Le Goff, and Jean Starobinski.

Gas Meter $81.25 A gas meter is used to measure the volume of fuel gases such as natural gas and propane. Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility. Gases are more difficult to measure than liquids, as measured volumes are highly affected by temperature and pressure. Gas meters measure a defined volume, regardless of the pressurized quantity or quality of the gas flowing through the meter. Temperature, pressure and heating value compensation must be made to measure actual amount and value of gas moving through a meter.Several different designs of gas meters are in common use, depending on the volumetric flow rate of gas to be measured, the range of flows anticipated, the type of gas being measured and other factors.

Light Meter $95.59 A light meter is a device used to measure the amount of light. In photography, a light meter is often used to determine the proper exposure for a photograph. Typically a light meter will include a computer, either digital or analogue, which allows the photographer to determine which shutter speed and fnumber should be selected for an optimum exposure, given a certain lighting situation and film speed. Light meters are also used in the fields of cinematography and scenic design, in order to determine the optimum light level for a scene. They are used in the general field of lighting, where they can help to reduce the amount of waste light used in the home, light pollution outdoors, and plant growing to ensure proper light levels.

Mass Flow Meter $70.1 A mass flow meter, also known as an inertial flow meter or a coriolis flow meter, is a device that measures mass flow rate of a fluid traveling through a tube. The mass flow rate is the mass of the fluid traveling past a fixed point per unit time. The mass flow meter does not measure the volume per unit time passing through the device; it measures the mass per unit time flowing through the device. Volumetric flow rate is the mass flow rate divided by the fluid density. If the density is constant, then the relationship is simple. If the fluid has varying density, then the relationship is not simple. The density of the fluid may change with temperature, pressure, or composition, for example. The fluid may also be a combination of phases such as a fluid with entrained bubbles. In a typical mass flow meter the fluid is contained in a smooth tube, with no moving parts that would need to be cleaned and maintained, and that would impede the flow.

Cycling Power Meter $60.54 High Quality Content by WIKIPEDIA articles A cycling power meter is a device on a bicycle that allows measuring of the power output of the rider. Most cycling power meters use strain gauges to measure torque applied, and, combined with angular velocity, calculate power. The Technology was adapted to cycling in the late 1980s and was tested in professional bicycle racing i.e.: the prototype Power Pacer (Team Strawberry) and by Greg LeMond with the SRM device. This type of power meter has been commercially available since 1989. Power meters using strain gauges are mounted in the bottom bracket, rear freehub, or crankset. Certain newer devices do not use strain gauges and instead measure power through handlebarmounted units that utilize the principles of Newtons Second Law by measuring a cyclists opposing forces (gravity, wind resistance, inertia, rolling resistance) and combining these with velocity to determine the riders power output.
