1. What are the power supply methods for electromagnetic flow meters? There are three main power supply methods for electromagnetic flow meters: 220V AC power supply, 24V DC power supply, and battery (mainly high-performance lithium batteries) power supply. 220V AC pure locust power supply: This is currently the most commonly used power supply method for electromagnetic flow meters. Due to the fact that most industrial sites have a 220V power supply, flow meters only need to be installed according to the requirements without the need for additional devices. They can start working after being powered on. Electromagnetic flow meters powered by 220V can be made into integrated or modular designs to meet different installation and usage needs. 24V DC power supply: This power supply method is mainly used in industrial sites where AC power is not allowed or low-voltage DC power is selected for safety reasons. In addition, when used in conjunction with a flow integrator, the integrator can also provide 24V DC power to the electromagnetic flowmeter for power supply. This method is particularly important in situations that require special voltage or safety requirements. Battery powered: In the absence of an external power source on site or for safety reasons, the electromagnetic flowmeter can be powered by batteries. This method can display instantaneous flow and cumulative flow on site, eliminating the cost of noise dissipation caused by connecting power supplies. In remote or difficult to access power environments, battery power supply is particularly important. The battery is usually a high-performance lithium battery, which can ensure that the flowmeter works normally for a period of time. In summary, there are various po_600x400.jpg)
2. Six commonly used classification methods for electromagnetic flow meters
The six commonly used classification methods for electromagnetic flow meters are as follows:
1. Classification by output signal connection and excitation (or power) connection system Four wire electromagnetic flow meters: The output signal line and the power blocking line (or the excitation wire between the flow sensor and the sensor) are composed of two sets of four wire systems with two wires each, which is the current mainstream system.
. Two line electromagnetic flowmeter: The output signal and power supply share the same wire, without the need for mains power supply, suitable for remote places without mains power supply. Its power supply design is divided into zero signal output current (4mA) supply, greater than zero signal output supply, and battery (or solar cell) supply. The battery powered sun wheel type is suitable for places where it is difficult to introduce mains electricity, and the battery life ranges from 1-2 years to 8-10 years.2. Classified Electromagnetic Flowmeters by Sensor and Converter Assembly Method: The sensor is connected to the pipeline, and the converter is installed in the instrument room or nearby, with a distance of tens to hundreds of meters.
. The signal cable adopts double-layer shielding. When measuring low conductivity liquids and the distance exceeds 30 meters, the dr
