Importance of Flow Measurement
We assist you in energy management
Compressed air and inert gases, such as helium, argon, nitrogen, and others, are very expensive. For example, the cost of compressed air is 8-10 times that of electricity, and the cost of industrial gases can be several times higher than that
Factors such as machine wear, leaks, low system energy conversion, fluctuations in production load, and unreasonable system structure or configuration can lead to much more energy being consumed than is actually needed, resulting in significant waste
Through continuous monitoring, you can anticipate issues and ensure that your system always meets your business needs
Our flow meters provide you with precise data at every location, such as instantaneous flow, total gas consumption, etc., allowing you to quickly identify high-consumption areas, leaks, inefficient usage, and overdue maintenance. This helps you save money and energy, significantly reducing gas costs

Technical Q&A
• What are the Common Flow Meter on the Market?
Differential Pressure Type: Pitot Tube Flow Meter; Orifice Flow Meter; Sonic Nozzle Flow Meter;
Positive Displacement: Roots Flow Meter;
Mass Flow: Thermal Mass Flow Meter; Coriolis Mass Flow Meter;
Velocity Type: Ultrasonic Flow Meter; Vortex Flow Meter; Turbine Flow Meter.
• Advantages and Disadvantages of Pitot Tube Flow Meter
Product Advantages:
IInsertion structure allows for installation and maintenance under pressure without stopping air flow, reducing construction costs; Can be used for DN40~600, covering a wide range of pipe diameters, allowing for ample inventory compression; Strong resistance to vibrations and electromagnetic interference; Wide measuring range, with a minimum limit of 5 Nm/s and a 1:60 turndown ratio; Almost no pressure loss, promoting energy efficiency.Product Disadvantages:
Pressure tap is prone to blockages; Multiple diameter usage with center-point measurement requires accurate mathematical flow models; Zero-point and linearity of differential pressure sensors will experience thermal drift and time drift with changing ambient conditions.
• Advantages and Disadvantages of Insert Thermal Mass Flow Meter
Product Advantages:
The plug-in structure can be installed and maintained under pressure without stopping the gas flow, and the construction cost is low. The plug-in installation does not require pipe cutting and docking, and the complete straight pipe section can be retained. It is universal for all pipe diameters in the range of DN25~600, which greatly reduces inventory. It is not afraid of vibration and electromagnetic interference. The measuring range is the widest among all flow meters, with a lower limit of up to 0.1 Nm/s and a turndown ratio of 1:2500. There is almost no pressure loss, which is beneficial to energy saving.Product Disadvantages:
Afraid of contamination and condensation; universality for multiple pipe diameters plus center point measurement requires an accurate flow mathematical model; the thermal measurement principle is highly nonlinear and requires an accurate calibration algorithm; the traditional thermal flow meter circuit will produce zero-point drift under different operating temperatures.
• Advantages and Disadvantages of Vortex Flow Meter
Product Advantages:
It has the strongest anti-pollution ability among the three flow meters and is suitable for harsh working conditions; it is not affected by gas type and gas composition, and the measurement is stable and reliable; it has good linearity and is relatively easy to calibrate and produce; it is the best choice for steam measurement: it has the smallest pressure loss, a wider measurement range than the orifice flow meter, and higher accuracy.Product Disadvantages:
It has weak resistance to vibration and electromagnetic interference. It has the narrowest turndown ratio and is prone to miss measurements at low flow rates. It needs to stop the gas flow and cut the pipe for installation, which has high construction costs and troublesome maintenance. Since it needs to cut the pipe for docking, centering errors or inconsistent pipe diameters will damage the straight pipe section and cause measurement errors. It has the largest pressure loss among the three flow meters.
