High-precision conductive liquid flow measurement solution with exceptional technical characteristics
The sensor delivers exceptional performance for low-flow applications, achieving a remarkable lower flow rate limit of 0.03 m/s with high precision. Even at extremely low flow velocities, it provides accurate and reliable flow data.
The outer shell is precision-cast from aluminum molds, ensuring not only an aesthetically pleasing and consistent appearance but also a seamless, weld-free design that facilitates quick installation/removal and simplifies maintenance.
Durability is enhanced by a thickened liner and arc-surfaced electrode, offering superior corrosion and abrasion resistance for challenging mixed-media environments, extending equipment service life under harsh operating conditions.
A key advantage is the complete absence of flow-obstructing components within the measurement pipe, resulting in zero pressure loss, lower straight-pipe requirements, and unique suitability for measuring fluids containing particulates.
At its core, a 16-bit embedded microprocessor enables fast, high-accuracy operations and programmable low-frequency excitation, which enhances measurement stability while maintaining low power consumption.
The adoption of SMD (Surface-Mount Device) technology and SMT (Surface-Mount Technology) ensures high circuit reliability, reducing solder joint failures and improving long-term operational stability.
At the scene, the measuring range can be modified online according to the actual needs of the users, so as to better match with the data acquisition needs without requiring factory return or specialized technicians.
The measurement results are independent of the physical parameters such as fluid pressure, temperature, density, viscosity, etc., maintaining accuracy across various operating conditions.
The sensor supports optional digital communication signal outputs including RS485, RS232, HART and Modbus, Profibus-DP, enabling easy integration into various industrial control systems.
With self-examination and self-diagnosis self-diagnosis and alarm function, it enables predictive maintenance, reducing unexpected downtime and improving system reliability.
Ultra-low EMI switching power supply, suitable for wide range of power supply voltage changes, with excellent anti-EMI performance, ensuring stable operation in electrically noisy environments.
