1. How to choose a steam flowmeter
Hello, KNKE, a well-known American imported steam flowmeter brand, is pleased to answer your question. Firstly, we need to start with the medium to measure whether the steam is superheated steam or saturated steam, and what is the temperature of the steam. If the normal temperature is below 250 ℃, a vortex flowmeter can be selected. If the temperature is too high, such as 400 ℃, then we need to consider choosing a V-cone or orifice flowmeter. Secondly, measuring the pressure of steam in pipelines is a very important aspect. Usually, the pressure is very high, around 1Mpa. Choosing a vortex flowmeter is acceptable. However, if the pressure exceeds this range, such as 4Mp or 6Mpa, our recommendation is to choose V-cone and orifice flowmeters. Once again, when it comes to imported orifice flow meters, the issue with measuring diameter is that vortex flow meters can usually only measure pipe diameters below DN300. If a large diameter is chosen, a plug-in vortex flow meter or orifice flow meter can be used. Finally, we also need to consider the current working conditions and temperature before installing the flow meter. We need to examine whether the surrounding environment is suitable for installing the flow meter. If there are interference sources, it will affect the measurement accuracy. The requirements for the straight pipe section are also very important, with a requirement of 10 in the front and 5 in the back. Which type of flow meter is suitable for pipeline identification environment? The KNKE brand coarse crack flow meter is also an important aspect that needs to be considered. If you think the answer is helpful to you, could you please raise your hand and give a thumbs
2. What is the difference or relationship between rotor type steam flowmeter and orifice flowmeter? There are also vortex flow meters, these three
A rotary flow meter is a type of flow meter that measures the flow rate of liquid or gas by rotating a wheel with blades, which is impacted by the liquid or gas.
. The tap water meter we use is a rotary blade type. But Im not sure if Yu Zhi has a rotary flow meter that can be used on steam. An empty plate flowmeter is a device that allows liquid or gas to flow through a perforated partition. The KV value of the hole in the middle of the orifice plate is of course fixed. When the KV value is determined, the flow rate of liquid or gas is calculated based on the pressure difference before and after. A vortex flowmeter is a device that allows liquid or gas to flow through obstacles in the middle of the flowmeter, creating vortices in the liquid or gas. Sensors calculate the number of vortices to determine the flow rate of liquids or gases. Usually, steam flow meters require the installation of pressure or temperature sensors. Because the temperature of steam also varies with changes in pressure. The amount of heat contained per unit volume of steam at different pressures or temperatures is different. The vortex flowmeter
