Fixed ultrasonic flowmeter

　　Fixed ultrasonic flowmeterIt is a widely used non-contact flow measurement instrument, mainly used for online flow measurement of various liquids in industrial sites.

　　Fixed ultrasonic flowmeterMeasure flow rate based on the time difference principle of ultrasonic propagation in fluids. It emits ultrasonic signals into the fluid inside the pipeline and receives signals reflected back from the fluid. Due to the flow of fluids, there will be differences in the propagation time of ultrasonic signals in the forward and backward directions. By measuring this time difference, the flow velocity of the fluid can be calculated, thereby obtaining the flow rate.

Performance characteristics of fixed ultrasonic flowmeter:

1. Large measurement range: By using different types of sensors, it is possible to measure the flow rate of pipelines with diameters ranging from DN15 to DN6000mm.

2. High measurement accuracy: linearity better than 0.5%, repeatability accuracy better than 0.2%, measurement accuracy better than ± 1%.

3. High reliability: By using low-voltage and multi pulse transmission circuits, the measurement accuracy, service life, and reliability are greatly improved.

4. Strong anti-interference ability: using dual balanced signal differential transmission and reception circuits, effectively resisting strong interference sources such as frequency converters, TV towers, and high-voltage lines.

5. Support Chinese and English menus: convenient for users with different language backgrounds to operate.

6. Memory function *: The latest 32-bit Cortex-M4 core CPU is used as the processor core, and 64 bit floating-point operations are used to calculate without losing accuracy.

7. High protection level: The protection level of a single meter can reach IP68, and it can work underwater for 2 meters.
