Clamp-on liquid flow meter is an instrument that uses ultrasonic technology to measure liquid flow. Its core features and applications are as follows:
Working principle
Time difference method: Calculate the flow rate by measuring the time difference between the propagation of ultrasonic waves in the fluid in the downstream and upstream directions. When the fluid flows, the propagation speed of ultrasonic waves in the downstream direction increases, and that in the upstream direction slows down. The time difference is proportional to the flow rate.
Doppler effect method: Applicable to liquids containing particles or bubbles, and the flow rate is calculated by measuring the frequency change (Doppler shift) of the reflected wave.
Core advantages
Non-invasive installation: No need to cut the pipeline or stop work, just clamp the sensor on the outer wall of the pipeline, which is easy to install and reduces maintenance costs.
Wide applicability:
Pipe diameter range: Supports pipelines from DN6 to DN6000mm.
Fluid type: Applicable to a variety of liquids such as water, oil, and chemicals. Some models can measure high temperature (such as 200℃) or high pressure (such as 10MPa) media.
Pipe material: Compatible with metal, plastic, fiberglass and other materials.
High precision and reliability: The accuracy is usually ±1%-±2%, the repeatability is better than 0.2%, and the long-term stability is high.
Multi-function output: Supports 4-20mA, pulse, RS485, HART and other signal outputs, which can be integrated into DCS or PLC systems to achieve remote monitoring and data recording.
Application scenarios
Industrial process control: In the chemical, petroleum, pharmaceutical and other industries, monitor the flow of cooling water, circulating fluid, additives, etc. to ensure process stability.
Municipal and environmental protection: used for urban water supply, sewage treatment, river flow monitoring, etc.
Energy management: Monitor the flow of boiler feed water, steam condensate, etc. to optimize energy consumption.
Selection recommendations
Measurement requirements:
Accuracy requirements: ±1% flowmeters are required for high-precision scenarios (such as trade settlement); ±2% can be selected for general monitoring.
Medium characteristics: Time difference method is preferred for clean liquids; Doppler method is selected for liquids containing particles.
Environmental conditions: Special materials (such as Hastelloy electrodes) or protection levels (such as IP68) are required for high temperature, high pressure or strong corrosive environments.
