Ultrasonic pipe flow meter is a flow meter that uses electronic principles to measure flow. Although it has its own calibration procedures, it has a common use and management model with the tap water industry.
Therefore, it is more standardized to include its performance requirements, measurement accuracy, calibration cycle, etc. in the cold water meter. How to choose a large-caliber ultrasonic flow meter?
Clear measurement requirements
Fluid type: Different types of fluids (such as clean water, sewage, oil, gas, etc.) have a direct impact on the selection of flow meters. The time difference ultrasonic flow meter is suitable for clean fluids, while the Doppler method is suitable for fluids containing solid particles.
Flow range: Determine the flow range to be measured, including the minimum flow, common flow, and maximum flow, to ensure that the measurement range of the selected flow meter can cover the actual needs.
Accuracy requirements: Determine the required measurement accuracy according to the specific application scenario. Generally speaking, the time difference method has higher accuracy and is suitable for occasions with higher accuracy requirements.
Consider environmental factors
Fluid temperature and pressure: The temperature and pressure of the fluid will affect the propagation speed of the ultrasonic wave, so when selecting the model, it is necessary to ensure that the working range of the flow meter can cover the actual working conditions.
Pipe size and material: The installation position of the flowmeter, the pipe diameter, and the material will affect the measurement results. Ensure the compatibility of the selected flowmeter with the pipe, and consider whether special installation accessories or adapters are needed.
Choose the right flowmeter type
Insertion ultrasonic flowmeter: The probe can be replaced online with pressure, with superior performance, and is almost maintenance-free in the later stage.
Ultrasonic pipe flow meter: Use a flange connection on the main pipe section, which needs to be implemented after the system is shut down. It is suitable for occasions that require long-term stable operation and high measurement accuracy.
External clamp ultrasonic flowmeter: It is installed with a special coupling agent, and the installation does not affect the operation of the system. It is suitable for temporary measurements or occasions that require quick installation.
Portable/handheld ultrasonic flowmeter: Built-in rechargeable battery, easy to carry, suitable for short-term comparison measurement or use in harsh outdoor environments.
