Flow meter

How they work The electromagnetic flowmeter utilizes the same principle as the electrical generator: when a conductor moves across a magnetic field a voltage is induced in the conductor, and the magnitude of the voltage is directly proportional to the speed of the moving conductor. If the conductor is a section of conductive liquid flowing […]

How they work Rotameter is a word said to have been coined in Germany early in this century, to denote what would otherwise have to be called an “a variable-aperture”(or variable area)flow rate meter employing a vertical tube and a “float”-hence the rapid worldwide acceptance of the name, which was subsequently adopted by a British

Customer request: Hope you and your team doing fine there. We are a leading textile manufacturer in Pakistan. We are producing steam from boilers and dispatch it to the processing area for different purposes. We know how much steam we generated from the boiler section, but need to know about the steam use at different

How they work How do you make a band play if it is an elastic one? Easy- just take it in your two hands, stretch it in front of your face about an inch away from your lips, and then blow on it. When the relationship between the tension in the rubber band and the

How they work In principle, positive displacement meters for gases should be similar to those used for liquids as described in section 5.1.1 above, and share their advantages and disadvantages. However, in practice, there is one very important difference. The energy in a flowing fluid is proportional to its density, and this means that a

How they work Until comparatively recently liquids being sold had to be measured by hand, using standard containers. Older readers will probably remember the days when a milkman who was asked for three pints would fill and empty a one-pint measure three times in succession. The first liquid quantity meters were the outcome of an

These are flowmeters-that is, instruments for determining the total flow rate in a pipe or duct-and must be confused with hot-resistor or hot-wire anemometers which are devices for measuring velocity at a point. As will appear from Figure 6.14 they utilize the tracer-dilution principle, with heat acting as the injected tracer. It is obvious that

 Points to Watch When Buying (a) When comparing quotations, look at specifications and/or guaranteed accuracies as well as prices. For example, square-wave excitation costs more than ordinary alternating current input, but gives better performance; it is a waste of money to pay for that extra performance if it is not really needed. (b) Make sure

Ordinary pressure has almost no effect on the viscosity of the liquid, only the liquid under high pressure the dynamic viscosity coefficient of the body increases with the increase of pressure. This is because the liquid is almost incompressible under ordinary pressure, while the compressibility of the liquid under high pressure reduces the gap between
