YHLDC electromagnetic
flowmeter is a fully intelligent electromagnetic flowmeter developed by our company, Beijing Yuhang Instrument Technology Co., Ltd. using advanced technology at home and abroad. Reliable performance. The converter circuit design adopts international advanced technology, the input impedance is up to 1015 ohms, and the common mode rejection ratio is better than 100db, which can measure the flow of fluid medium with lower conductivity. The sensor adopts the magnetic circuit structure of non-uniform magnetic field technology, and the magnetic field is stable and reliable. It is our company's consistent aim to make customers buy with confidence, use them with peace of mind, and provide satisfactory service.
Two use requirements
The selection of the instrument is a very important work in the application of the instrument. The relevant data shows that 2/3 of the faults of the instrument in the actual application are caused by the wrong selection or installation of the instrument, please pay special attention.
Electromagnetic flowmeter selection instructions Correct selection of electromagnetic flowmeters is a prerequisite for ensuring good use of electromagnetic flowmeters. What type of electromagnetic flowmeter should be selected should be determined according to the physical and chemical properties of the fluid medium being measured, so that the diameter, flow range, lining material, electrode material and output current of the electromagnetic flowmeter can be adapted to the fluid being measured. Nature and nature and flow requirements. Measurable fluid: From the working principle of electromagnetic flowmeter, it can be known that the fluid that can be used to measure the flow rate of electromagnetic flowmeter must be conductive. Select the corresponding electromagnetic flowmeter to measure the flow, so the non-conductive gas, steam, oil, acetone and other substances cannot use the electromagnetic flowmeter to measure the flow. Determination of sensor diameter: The flow rate of the flowmeter is preferably in the range of 0.3-15m/s. At this time, the diameter of the flowmeter can be selected to be consistent with the diameter of the user's pipeline. When the flow velocity is lower than 0.3m/s, it is better to increase the flow velocity locally at the instrument part
Separate type: that is, the sensor and the converter are installed in different places separately. Generally, the separate type is used when the following situations occur. When ordering, the separation distance of the transducer of the sensor should be indicated, generally not more than 100m, and the transducer is wall-mounted.
