Selection of installation point for electromagnetic sewage flow meter

Abstract: The selection information for the installation point of the electromagnetic sewage flow meter is provided by the excellent manufacturers of flow meters and flow meters. Before installing instruments and instrument usage management, it is necessary to understand the installation needs before talking about the application. Let's take a look at some of the things that need to be paid attention to when choosing the installation point of the intelligent electromagnetic sewage flowmeter. 5 points: 1. Try to avoid ferromagnetism. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the selection of installation points for electromagnetic sewage flowmeters. Before installing instruments and instrument usage management, it is necessary to understand the installation needs before talking about the application. Let's take a look at some of the things that need to be paid attention to when choosing the installation point of the intelligent electromagnetic sewage flowmeter. 5 points: 1. Try to avoid ferromagnetic objects, high radio frequency, strong vibration interference sources and equipment with strong electromagnetic fields (such as high-power motors, large transformers, etc.), so as to avoid the magnetic field affecting the working magnetic field and flow signal of the sensor. 2. It should be installed in a dry and ventilated place as much as possible, and it should not be installed in a humid and water-prone place. 3. The sun and rain should be avoided as much as possible, and the ambient temperature should be -20--60 ℃ and the relative humidity should be less than 95%. 4. Choose a place that is convenient for maintenance and activities. 5. The electromagnetic flowmeter should be installed at the back end of the pump, never on the suction side; the valve should be installed downstream of the flow. The above are some of the differences between the installation point selection of the intelligent electromagnetic sewage flowmeter and the traditional electromagnetic flowmeter. In addition, there are differences in the applied technology. The smart electromagnetic flowmeter uses the most modern excitation technology. The application of intelligent electromagnetic flowmeter excitation technology not only reduces the influence of electrode polarization potential, mud interference and flow noise, but also changes the form of power frequency interference, which is convenient for synchronous sampling technology to deal with power frequency interference noise and avoid the influence of power frequency interference . At present, the electromagnetic flow sensor adopts power frequency frequency synchronous three-value low-frequency rectangular excitation and dual-frequency rectangular wave excitation, thereby improving the entire anti-interference ability of the electromagnetic flowmeter and improving the measurement accuracy and reliability of the electromagnetic flowmeter. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
