316SS Stainless Electromagnetic Flow Meter Sensor Magnetic Flowmeter
Application:
Due to its unique advantages, it is widely used in the fields of petroleum, chemical industry, steel, light industry, sewage processing, environmental protection, water conservancy project and pharmacy to measure the volume flow of the conducted liquid mediums, such as acid, alkali, salt solution and so on.
Features:
1. No moving and blocked flow parts in the pipeline, almost no additional pressure loss in the measurement.
2. Measurements results are independent of physical parameters, such as flow distribution, fluid pressure, temperature, density and viscosity.
3. On-site modification of the measuring range available.
4. LCD display, easy to use and simple to operate.
5. Using SMD devices and SMT technology.
6. Using 16-bit embedded processors with fast speed and high accuracy, enhancing the stability of measurement.
7. Anti-interference, reliability, measurement range up to 150:1.
8. Ultra low EMI switch, wide range of power supply voltage.
9. RS485, RS232, Hart and Modbus digital communication signal output.
10. Self-checking function.

Electromagnetic flowmeter maintenance and installation precautions
1. Routine maintenance
Visually inspect the instrument for periodic inspection, check the surrounding environment of the instrument, remove dust, ensure that there is no other substance in the water, check whether the wiring is good, check whether there is a new strong electromagnetic field device near the instrument or a new cable meter. If the measuring medium is easy to contaminate the electrode or precipitate or scale in the measuring tube wall, it should be regularly cleaned and cleaned.
2. Fault finding
After the flowmeter starts to be put into operation or is put into operation for a period of time, it is found that the instrument is not working properly. You should first check the external condition of the flowmeter, such as whether the power supply is good, whether the pipeline is leaking or is in a non-full-tube state, and there are air bubbles in the pipeline. Whether the signal cable is damaged or not, and whether the converter output signal (ie, the rear instrument input circuit) is open. Remember to blindly disassemble the flowmeter.
3. Sensor inspection
Test equipment: one 500MΩ insulation resistance tester, one multimeter.
