Flow meter

We know that no matter it is a solid, liquid, or gas, the matter is divided into the conductive matter, dielectric (insulating matter), and semiconductor matter according to its electrical properties. For liquids alone, there are also conductive liquids and non-conductive liquids. In conductive liquid substances, there are a large number of charged free particles […]

There are three common forms of matter： Solid, liquid, and gas, their physical properties are very different. In physics, a fluid is a liquid, gas, or other material that continually deforms (flows) under applied shear stress, or external force. They have zero shear modulus, or, in simpler terms, are substances that cannot resist any shear force applied to them. Although

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of “thickness”: for example, the syrup has a higher viscosity than water. When we observe the water flow in the river channel, we can see that the water velocity in

Definition – What does Flow Rate mean? Flow rate can be defined as the speed or rapidness of a fluid or gas that flows through a channel or a vessel. This rate is a means of measuring the speed or velocity of liquid or gas that is meant to flow from a particular channel, pipe, or vessel.

The measurement of flow rate, temperature, pressure, level, etc. is the same as thermal measurement, which is one of the important measurement parameters in industrial and agricultural production process control. Flow measurement has an inseparable relationship with people’s daily life. Therefore, as a flow meter for flow measurement, it has a wide range of applications.

Human minds like a parachute- works best when open. Chan 9.1 Introduction In principle, there is no room for argument about what the right flowmeter for the job means. The right flowmeter is the one that will do the job adequately at the lowest possible total cost, including initial cost, and the indirect costs arising

How they work These meters operate on the same principle as turbine meters for liquids, as described in section 5.3.1. Because of the relatively low kinetic energy of a flowing gas, however, it is necessary to make a significant difference in shape. A turbine meter for gases, as shown in Figure 5.11, always has a

How they work A turbine meter is a name given to one particular type of rotating flow meter. It consists of a short length of pipe in the center of which there are two bearings supported by spiders. A propeller, large enough to fill the cross-section of the pipe almost completely, is mounted so that

Exterior The appearance of the flow meter should be complete and good, and the markings (nameplate, flow direction mark, explosion-proof mark, manufacturing measuring instrument license, etc.) should be correct, complete, and clear. There should be no scratches and other damage on the connecting surface of the external connection. Fasteners should be combined. It is firm

Factory inspection Each flowmeter must be inspected to be qualified before leaving the factory. Only when all inspection items are qualified can the flowmeter be determined to be qualified, and repairs are allowed if there are unqualified items. Timing of type evaluation Type evaluation must be carried out when one of the following conditions exists:
