YUNYI YFVW300V Wireless vortex flowmeter

Product catalog summary

General Information: The manual provides guidance on installing, using, and maintaining the YFVW300D Vortex Flowmeter. It emphasizes the importance of safety precautions when handling hazardous or flammable liquids and working in hazardous environments. The vortex flow meter is used in various industries such as petroleum, chemical, and power.

Operation Principle: The YFVW300D Vortex Flowmeter measures the volume/mass flow of liquids, gases, and steam using the Karman vortex principle. It features advanced differential algorithms for improved immunity to vibration and noise.

Technical Data: The flow meter is designed for measuring systems with a flow sensor and signal converter. It supports a range of applications, including gas, liquid, and steam, with specific accuracy rates for each. The device operates under conditions similar to EN 29104 standards, with specific requirements for electrical conductivity, temperature, and pressure.

Installation Guidelines: Proper installation is crucial for accurate measurement. The flow sensor must be fully filled, and specific lengths of straight pipe runs are required upstream and downstream to ensure accuracy. The manual provides detailed instructions on creating backpressure to prevent cavitation.

Safety and Maintenance: Regular calibration is recommended at least once a year. The manual advises against purging the flow meter with compressed air and provides guidelines for handling minor spills during maintenance.

The recommended quidelines are given to enhance accuracy and maximize performance. Distance given here are minimum requirements; Double them for desired straight pipe lengths. ik Upstream: allow a minimum straight pipe length at least 10 D the internal diameter of thepipe. For example, with the 50mm pipe, there should be 500mm of straight pipe immediately+upstream.Desired upstream straight pipe length is 1000mm. ik Downstream: allow a minimum straight pipe length at least 5 D the internal diameter of the+pipe, For example, with the 50mm pipe, there should be 250mm of straight pipe immediately...
