It has obvious advantages such as compact structure, intuitive and clear readings, high reliability, no external power interference, lightning resistance, and low cost.
The selection requirement for wireless transmission function of turbine flowmeter is a key link to ensure efficient, accurate and secure data transmission in industrial automation and remote monitoring systems. When choosing this feature, it is necessary to carefully consider the following core elements to ensure that it can meet the diverse needs of practical application scenarios.
The primary consideration is the stability and reliability of wireless transmission. This requires the wireless communication module equipped with the turbine flowmeter to have strong anti-interference ability, be able to work stably in complex electromagnetic environments, reduce packet loss and error rate during data transmission, and ensure data integrity and real-time performance.
Secondly, transmission distance and coverage range are another important consideration. According to the on-site layout and the location relationship of the monitoring center, wireless communication technologies with appropriate transmission distances, such as LoRa, NB IoT, or 4G/5G, need to be selected to achieve wide area coverage and efficient data transmission.
Furthermore, security and encryption mechanisms are indispensable. In the process of data transmission, advanced encryption algorithms and security protocols such as TLS/SSL, AES, etc. must be used to encrypt the data, prevent information leakage and illegal access, and ensure the security and privacy protection of data transmission.
In addition, power management is also a major concern. Choosing a low-power wireless communication solution, combined with intelligent wake-up and sleep mechanisms, can effectively extend the working life of the turbine flowmeter and reduce maintenance costs.
Finally, compatibility and scalability are equally important. The selected wireless transmission function should be able to seamlessly integrate with existing industrial automation systems, while reserving sufficient interfaces and protocol support for future system upgrades and functional extensions. In summary, the selection of wireless transmission function for turbine flow meters requires a comprehensive consideration of the above factors to create an efficient, safe, and reliable industrial automation data transmission system., To create an efficient, secure, and reliable industrial automation data transmission system.

Manufacturer of threaded connection liquid turbine flowmeter
Threaded connection turbine flowmeter is the main type of velocity flowmeter. When the measured fluid flows through the turbine flowmeter sensor, the impeller rotates under the action of the fluid, and its speed is proportional to the average flow velocity of the pipeline. At the same time, the blades periodically cut the magnetic field lines generated by the electromagnet, changing the magnetic flux of the coil. According to the principle of electromagnetic induction, a pulsating electric potential signal, namely an electric pulse signal, is induced in the coil. The frequency of this electric pulse signal is proportional to the flow rate of the measured fluid.
