Principle and structure<\/h4>\n

The LUGB vortex flowmeter is a velocity flowmeter designed based on the Karman vortex principle. It is primarily used for measuring the flow of media such as gas, steam, or liquids in industrial pipelines. Depending on the model selected, it can measure the temperature, pressure, instantaneous flow rate, and cumulative flow rate of media in industrial pipelines. It also features pulse output, 4-20mA analog signal output, RS485 communication (Modbus RTU protocol), and GPRS internet access.<\/p>\n

Product Features<\/h4>\n

1.High reliability, good stability, simple structure, and easy maintenance;<\/p>\n

2. The sensor's output pulse frequency is linearly proportional to the fluid flow rate, with no zero drift and high stability;<\/p>\n

3. Various structural options available;<\/p>\n

4. Liquid measurement accuracy is \u00b11.0%, and gas measurement accuracy is \u00b11.5%;<\/p>\n

5. Energy-saving and low pressure drop;<\/p>\n

6. Flexible installation options;<\/p>\n

7. Multiple circuit protection methods;<\/p>\n

8. High-precision probe and piezoelectric crystal vortex sensor for stable signals;<\/p>\n
