1. What are the brands of imported mass flow meters or mass flow controllers? Overall, only domestic brands such as Qixing and INHA are still reliable for gas mass flow controllers. The main imported brands are European and American brands such as BROOKS and MKS. 2. Why are there fewer and fewer companies using imported thermal gas mass flow meters?
There are several possible reasons why companies are no longer inclined towards using imported thermal gas mass flow meters to measure flow.. 1. Cost considerations: Imported thermal gas mass flow meters often have higher prices, including the cost of the equipment itself and maintenance and repair costs. Enterprises may be more inclined to seek more cost-effective local alternatives or other technologies.
2. Technological development: With the passage of time, domestic flow measurement technology has developed and grown steadily.
. Newer local technologies may be comparable to or even better than imported products in terms of performance, stability, and reliability. This reduces the demand for imported products by enterprises. Supply chain issues: Imported products may be affected by supply chain instability, such as tariffs, transportation delays, or political issues. These issues may make it difficult for businesses to obtain the imported products they need, so they turn to local alternatives. 4. Safety and compliance considerations: Some industries (such as chemical, energy, manufacturing, etc.) have high requirements for the accuracy and reliability of flow measurement. Due to potential quality standards, certification, and compliance issues with imported products, companies may prefer to use local products to meet safety and compliance
3. What is the unit of mass flowmeter? Hello, KNKE, a manufacturer of imported flow field meters from the United States, is pleased to answer your question. The gas mass flow unit of the KNKE imported orifice flowmeter from the United States is generally expressed in sccm (Standard Cubic Centimeter per Minute) and slm (Standard Liter per Minute). This means that under different usage conditions, the flow indicated by this instrument is the standard flow rate. The standard state is as follows: air pressure -101325Pa (760mm Hg); Temperature -0 ℃ (273.15K). This is an important difference between this instrument and other flow meters, and it is also where SCCM and SLM differ from mL/min and L/min. For most users, the representation method of volumetric flow rate is very habitual and easy to use, but there are also users who need to know the mass of the medium flowing through per unit time (such as g/min), which is easily achievable. Because the gas density under standard conditions is a constant that can be easily found, a simple multiplication (multiplying the density by several slm) can be performed to achieve it. So, the volumetric flow rate under standard conditions is equivalent to the mass flow rate. 4. How to use gas mass flowmeter correctly
To use gas mass flowmeter correctly, it is necessary to follow the installation, selection, use and maintenance, and special scenario handling specifications. The specific operation is as follows:
