Flow meter

An orifice plate is simply a plate with a hole in it, forming a partial obstruction to the flow. As will be seen from Figure 3.6, the flowing fluid follows the same kind of path as it does in the venturi tube. However, the narrowest part of the flow stream is not in the orifice […]

A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. Nozzles can be used in two quite different ways: as differential pressure meters for liquids and gases; or as sonic (critical) velocity regulating and metering

The wetted parts in SS 316, preferred. Zero Instrument supply: Thanks for your interest in our

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
