Flow meter

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

  Zero Instrument supply to the customer: Since the medium is steam, here we quote for you the steam vortex flow meter. Integrated temperature and pressure compensated vortex flowmeter, Field display, 24V power supply, 4-20mA output (3-wire) + RS485 communication, 304 stainless steel meter body, Temperature resistance-40 ~ 250 °C, Protection Class IP65, Flange connection

 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

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.
