Click the Chinese display LCD, display the cumulative flow, instantaneous flow velocity, flow percentage and so on. ◆ Bi-directional measurement system can measure forward flow, reverse flow. Using a special production process and quality materials to ensure product performance remains stable over a long time. Air conditioning water flow measurement principle: Measuring principle KH-LDE-type air-conditioning water flow meter is based on Faraday's law: conductive liquid cutting magnetic field lines, the potential induced in the conductor in a magnetic field, the EMF E is: E = KBVD wherein: when the average flow velocity D ---- measuring the inside diameter of pipe cross-section measuring flow meter constant K ---- B ---- V ---- measuring magnetic induction within the pipe cross-section, the conductive liquid at a speed V flowing through a magnetic field perpendicular to the flow direction, the flow of conductive liquid induces a voltage proportional to the average velocity, the induced voltage signal through an electrode which two or more direct contact with the liquid are detected, and sent through the cable converter through intelligent processing, and LCD display or converted into a standard signal output 4 ~ 20ma and 0-1khz. How correct selection: instrument selection is very important instrumentation work, the data indicate that the instrument has practical application in fault 2/3 meter selection is wrong or incorrect installation caused, please pay special attention . ◆ collect data: 1. 2. The maximum flow measured fluid composition, the minimum flow 3. The maximum working pressure maximum temperature, minimum temperature ◆ measured fluid must have a certain conductivity, electrical conductivity> 5μS / CM maximum flow and minimum traffic must comply with the following table count: mm caliber flow range m3 / h mm caliber flow range m3 / h φ15 0.0636 ~ 6.36 φ450 57.23 ~ 5722.65 φ20 0.11 ~ 11.30 φ500 70.65 ~ 7065.00 φ25 0.18 ~ 17.66 φ600 101.74 ~ 10173.6 φ40 0.45 ~ 45.22 φ700 138.47 ~ 13847.4 φ50 0.71 ~ 70.65 φ800 180.86 ~ 18086.4 φ65 1.19 ~ 119.4 φ900 228.91 ~ 22890.6 φ80 1.81 ~ 180.86 φ1000 406.94 ~ 40694.4 φ100 2.83 ~ 282.60 φ1200 553.90 ~ 55389.6 φ150 6.36 ~ 635.85 φ1600 723.46 ~ 72345.6 φ200 11.3 ~ 1130.4 φ1800 915.62 ~ 91562.4 φ250 17.66 ~ 176.25. φ2000 1130.4 ~ 113040.00 φ300 25.43 ~ 2543.40 φ2200 1367.78 ~ 136778.4 φ350 34.62 ~ 3461.85 φ2400 1627.78 ~ 162777.6 φ400 45.22 ~ 4521.6 φ2600 1910.38 ~ 191037.6 ◆ actual maximum working pressure must be less than the rated working pressure flowmeter. ◆ The maximum operating temperature and the minimum temperature must meet the requirements specified temperature meter. ◆ determine whether there exists a negative pressure situation. You can select the appropriate electromagnetic flowmeter according to the table in the flow, and if the inner diameter of the electromagnetic flowmeter selection process and the inner diameter of the pipe is now inconsistent, should shrink tube or flaring. ◆ If the pipes shrink tube should be considered due to the reduction of the pressure loss caused will affect the process. ◆ consider the price, you can choose a smaller caliber electromagnetic flowmeter, the relative reduction in investment. ◆ When measuring clean water flow rate when the economy 1.5-3m / s, measured at a solution and crystallization, should be properly increase the flow rate, 3-4m / s is appropriate, play a self cleaning action to prevent the adhesion of deposition; measuring pulp ◆ consumption when grinding fluids, etc., should be appropriately reduced velocity, 1.0-2m / s is appropriate, in order to reduce wear on the lining and the ground electrode. Practical applications rarely exceed 7m / s, more than 10m / s is even more rare.
