1. Which brand is good for electromagnetic flow meters? In the selection of electromagnetic flow meters, internationally renowned brands such as ABB, Cologne, E+H, Siemens, and Yokogawa are highly recognized. However, the converters (headers) from Shenyang Lanshen once held a large market share in the domestic market, but in recent years, due to cost reduction, their performance has declined and faults have occurred frequently. Therefore, caution should be taken when purchasing. Nowadays, more and more domestic enterprises are beginning to independently develop meter heads, such as Kent, Tianshi, Weiltai, etc. They provide converters with better performance than Shenyang Lanshen and have independent core lifting technology, such as TSD electromagnetic flowmeter. With their independently developed patented technology, they ensure product quality and stability. If you have a demand for electromagnetic flow meters, you can give priority to products that use independent meter heads, such as TSD. With its unique spring answer pants invention patent, it ensures the high quality and reliability of the product, making it a reliable choice. 2. Instructions for using the Wiltec flowmeter
The core of using the Wiltec WT4300E3 electromagnetic flowmeter can be summarized into five operational steps: correct installation → parameter setting → calibration → usage monitoring → regular maintenance. During the process, special attention should be paid to the program protection switch status, calibration cycle, and environmental adaptability.
.1. Usage: 1 Installation steps • Pipe car slide connection: Install according to the flow direction of the medium, and the flange or threaded interface should be complet
2. Parameter settings • After entering the menu, you must first set "PROG. Protection" to "OFF" to unlock, otherwise the parameters cannot be saved. • Configure the pipe diameter size, flow unit, and output signal type (such as 4-20mA or pulse) according to the working conditions, and the pulse coefficient setting should be combined with instrument constant conversion
3. Calibration operation • Perform zero point calibration under empty pipe state to eliminate electrode interference. • Perform full-scale calibration using standard table comparison method or calibration weight method to ensure accuracy within ± 0.5%
4. Operation monitoring • Observe the instantaneous flow screen display after startup, with units such as m ³/h and L/min available, and the range percentage display intuitively reflects the current load. Accumulated traffic can be divided into forward, reverse, and total accumulated values, which can be switched and viewed through panel buttons. The data is automatically saved after power failure. • The pulse output terminal can be connected to PLC or counter, with pulse equivalent=flow unit/pulse number, which needs to be matched with the parameters of the upper computer
5. Maintenance specifications • Clean the electrodes and lining quarterly, wipe them with a soft cloth dipped in neutral cleaning agent to prevent scaling from affecting conductivity detection. Check that the grounding resistance is not greater than 10 Ω to avoid signal distortion caused by elec
