Mud Flow Meter

Mud flow meter specifically designed with a wide temperature range of Chinese liquid crystal display backlight, functional and practical, intuitive display, easy operation, can reduce the mud flow meter other English menu inconvenience. 4-6 In addition, we designed an exclusive multi-electrode structure, to further ensure the accuracy and at any time without grounding rings, reducing the volume and instrumentation installation and maintenance trouble. Accuracy from the fluid density, viscosity, temperature, pressure and conductivity change impacts, mud flow sensor sensing the voltage signal with a linear relationship between the average velocity, and therefore high accuracy. The unimpeded flow of slurry flow measurement piping parts, so there is no additional pressure loss; measurement tube with no moving parts, so very long sensor life. Since the induced voltage signal meter slurry is filled in the space formed in the magnetic field, is the average of the surface pipe set, so the sensor short straight pipe length is 5 times the pipe diameter. Only part of the sensor electrode in contact with the liner and the measured liquid, as long as a reasonable choice of electrode and lining material can be resistant to corrosion and wear. How to correct selection mud flow meter: instrumentation instrument selection is very important work, the data indicate that the instrument has practical applications in fault 2/3 of the selection is wrong or incorrect installation of the instrument caused, Please pay special attention. ◆ collect data 1. Measured fluid ingredients 2. Maximum flow, minimum flow 3. Maximum working pressure 4. Maximum flow maximum temperature, minimum temperature ◆ measured fluid must have a certain conductivity, electrical conductivity> 5μS/CM mud flow meter and minimum flow must match the number in the following table: diameter mm Flow range m3 / h mm diameter 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 mud flow meter must be less than the actual maximum working pressure flowmeter rated working pressure. Maximum operating temperature and the minimum temperature must meet the requirements specified temperature meter. Determining whether there is a negative pressure condition exists. You can select the appropriate electromagnetic flowmeter according to the traffic on the table, and if the inside diameter of the flowmeter selection process piping and now does not match the inside diameter should be shrink tube or pipe expansion. If the pipeline shrink tube should be considered due to the reduction of the pressure loss caused will affect the process. From product price consideration, you can choose a smaller caliber electromagnetic flowmeter, the relative reduction in investment. When measuring clean water, when the economic velocity 1.5-3m / s, measured when the solution is easy to crystallize, should suitably increase the flow rate ,3-4m / s is appropriate, play from cleaning to prevent the adhesion of deposit and other effects; measuring pulp, etc. ◆ grinding fluid consumption, should be appropriate to reduce the flow rate ,1.0-2m / s is appropriate to reduce the wear on the lining and the ground electrode. Practical applications rarely exceed 7m / s, more than 10m / s is even more rare. Correct wiring mud flow meter: ① excitation cable can be used YZ medium rubber cables, the length of the signal cable as ② signal cables and other power supply cables must be strictly separated, the same can not be laid in a tube, can not be laid parallel, not twisted together, should be worn separately inside the pipe. ③ signal and field current cables as short as possible, the extra cable roll together, the excess cable should not be cut and re-welded joints, the cable into the sensor electrical interface, made at the port of U-shaped, so you can prevent rainwater penetrate into the sensor. ④ points connecting the meter body mud field between cable and converter with special wiring is completed, the converter and external connections to the same body mud flow meter.
