Main Features
1.High-precision measurement advantages
Its measurement error range is extremely small, and it can usually control the error within a very small percentage. In the measurement scenarios of different fluids, whether it is corrosive chemical liquids, industrial slurries containing certain impurity particles, or clear pure water, it can rely on advanced electrode sensing technology and precise signal processing algorithms to ensure the accuracy of the measurement results.
2.Wide measurement range characteristics
It can be applied to a variety of fluid media, such as common liquid water, oils, various acid and alkali solutions, and can also meet the flow measurement needs of gaseous substances.
3.Reliable and stable guarantee
The multi-electrode measurement system adopts a non-contact measurement method, which makes it less susceptible to changes in fluid properties and impurities. The principle is that non-contact measurement avoids problems such as wear and corrosion caused by direct contact with the fluid, and key components such as sensors are in a relatively independent and stable working environment. For changes in fluid properties, such as changes in fluid temperature, density, viscosity and other parameters, since the system mainly relies on the principle of electromagnetic induction to capture the potential difference generated by fluid flow for measurement, rather than relying on physical contact feedback with the fluid, these changes will basically not interfere with the accuracy of the measurement signal.
4.Easy-to-maintain design
The multi-electrode measurement system is very simple and clear in structural design, and is also extremely easy to operate. Its overall structure does not have overly complex mechanical parts and cumbersome connection lines. Users only need to understand the basic operating procedures to easily start measuring operations.
In terms of daily maintenance and care, the system's electrodes and other key components are mostly designed to be easy to disassemble and replace. When an electrode shows signs of aging or failure, the staff can quickly replace it individually without large-scale disassembly and maintenance of the entire system. In addition, the system's shell design is easy to open, which facilitates internal cleaning, inspection and other maintenance work, reducing the cost and difficulty of use.
