ESMTDS100H Ultrasonic Flow meter for PVC Carbon Steel Stainless Steel Water Pipes
Working Principle
The time-difference method is usually used, where an external clamp-on sensor emits and receives ultrasonic waves, measures the difference in propagation time of the ultrasonic waves in the fluid in the downstream and upstream directions, and then calculates the fluid flow velocity. Combined with parameters such as the pipe's cross-sectional area, the flow rate can be determined.
Product Features
1. Portability: Small in size and lightweight (usually <2kg), equipped with a dedicated carrying case, built-in high-capacity lithium battery, capable of continuous operation for more than 8-12 hours, suitable for field or high-altitude work.
2. Non-invasive Measurement: Uses an external clamp sensor, directly clamped onto the pipe wall, no need to drill holes, interrupt flow, or install valves, causing zero interference with the production process.
3. Plug and Play: After powering on, input the pipe parameters (material, outer diameter, wall thickness, medium), the device automatically calculates the sensor installation spacing and indicates the positions, completing measurement within minutes.
4. Data Recording and Export: Built-in memory can record thousands of historical data entries (time, flow, signal strength, etc.), supports export to computer via USB to generate Excel reports, convenient for subsequent analysis.
5. Multilingual and Intelligent Guidance: Interface usually provides Chinese and English switching, with detailed installation guides and signal quality diagnosis functions, assisting operators to quickly get started.
