Product Details

KUF Time Difference Ultrasonic Flow Meter

Widely used for online measurement and system monitoring of almost all liquids in petrochemicals, metallurgy, electricity, water conservancy, water supply and drainage, energy monitoring, etc.

The measurement linearity is better than 1.0%, the repeatability is better than 0.2%, and the measurement accuracy reaches ± 1.0%.
Available in both Chinese and English, both positive and negative flow rates as well as net flow rate can be measured.
Optimized intelligent signal adaptive processing eliminates the need for any circuit adjustments and speeds up the response time of the flow meter, ensuring accuracy.
The use of balanced differential transmission and balanced differential reception technology greatly improves anti-interference performance and adaptability, making it suitable for high-power frequency converter working environments.
The use of electrically isolated DC power supply and lightning protection circuit greatly improves the reliability and anti-interference performance of the host.
Low hardware quantity, low power consumption, strong anti-interference ability, high reliability, and good adaptability.
Equipped with RS-232/485 interface and comprehensive network/communication protocols, while supporting standard protocols such as MODBUS.
It has achieved the measurement of non-conductive and special media, and has a certain function of automatic identification of media parameters.
Diversified input and output options include frequency, current, and OCT output.
Built in daily, monthly, and yearly accumulator, with power on/off management function and self diagnostic function for working status.
All accumulated content, date and time, etc. are stored in the memory, and there will be no problem of power loss.
The power supply is available in AC220V, DV24V, and 3.6V lithium batteries.
Can meet the flow measurement requirements of the vast majority of clean water, sewage, and various chemical liquids.
