First of all, let's understand what is cheap slurry electromagnetic flowmeter products. The so-called cheap slurry electromagnetic flowmeter products is actually an cheap slurry electromagnetic flowmeter products specially used to measure slurry. Its working principle is the same as that of ordinary electromagnetic flowmeter. It is an instrument that uses the principle of electromagnetic induction to measure the flow of conductive fluid according to the electromotive force induced by the conductive fluid when passing through the external magnetic field. Let's talk about the selection method of cheap slurry electromagnetic flowmeter products.
Selection method of cheap slurry electromagnetic flowmeter products
1. The flow of cheap slurry electromagnetic flowmeter is determined according to the maximum flow.
2. Determine the diameter of the flowmeter according to the flow of the slurry electromagnetic flowmeter products and the size of the industrial pipeline. Generally, the flowmeter consistent with the pipeline is selected.
3. The lining of the flowmeter is selected according to the measured medium characteristics of cheap slurry electromagnetic flowmeter products. Such as temperature, corrosivity, whether there may be negative pressure in the pipeline, etc. The general lining includes PTFE, soft rubber, hard rubber, PFA, ceramics and so on.
4. Select the material of measuring electrode according to the dielectric characteristics of cheap slurry electromagnetic flowmeter products. Generally 304, 316, Hastelloy, titanium, tantalum and so on.
5. Select the pressure grade of flanges connected on both sides according to the pressure grade of process pipeline of cheap slurry electromagnetic flowmeter products.
6. The protection grade of cheap slurry electromagnetic flowmeter products shall be selected. If the whole sensor is underwater, IP68 shall be selected
The above is the sensor part of cheap slurry electromagnetic flowmeter products. There is also the transmitter part of cheap slurry electromagnetic flowmeter products.
1. According to the requirements of installation position, determine whether to choose integrated or split type. 2. What type of output is required, 4-20 mA signal, Hart, PROFIBUS PA, FF, etc.
3. Whether explosion-proof requirements are required. Determine the explosion-proof grade.
