The length L is the distance between the electrodes and equals the pipe diameter. Hover mouse over icon for application notes. Ensure that no welding slag or debris remains in the pipeline. , the flowmeter has wide versatility and strong interchangeability. In principle, water flow meter types are: Electromagnetic (magnetic), Turbine, Ultrasonic, and DP. Some models claim higher accuracy, and the basic error is only (± 0.2% ~ ± 0.3%) R. But, there are strict installation requirements and reference conditions, For example, the temperature is 20-22°C. into integrated electromagnetic flowmeters and split electromagnetic flowmeters. Use the verification medium to circulate in the piping system for a certain period of time. Save my name, email, and website in this browser for the next time I comment. Remove dust and dirt. The operation principle of a magnetic flow meter or mag meter is based upon Faraday’s Law. If a multi-motor structure, on the cathodic protection pipeline. You can contact us for magnetic flow meter PDF. Or. The range of the electromagnetic flowmeter is. Available process connections include hot-tapped, DIN and NPT threads, Insert the electromagnetic flowmeter according to the situation of the pipeline. Faraday’s Law states the voltage generated is proportional to the movement of the flowing liquid. Material can be 316 stainless steel or special material. Reasonable selection of sensor lining and electrode material. Whether there are air bubbles in the pipeline. When installation is necessary, ventilation measures must be taken. (4) Check that the insulation resistance between X, Y and C should be above 200MΩ. Whether the output signal of the converter (that is, the input circuit of the rear instrument) is open. from materials that can withstand corrosion. Note: The mass flow meter can be used in both directions. The Magnetic Flow Meter Construction consists of an electrically insulated or non conducting pipe, such as fibre glass, with a pair of electrodes mounted opposite each other and flush with the inside walls of the pipe, and with the magnetic coil mounted around the pipe so that a magnetic field is generated in a plane mutually perpendicular to the axis of the flow meter body and to the plane of the electrodes. The remaining flowmeters are almost always tested when they leave the factory. opened to adjust the flow at the verification point; During the calibration process, the flow stability of each flow point should be within 1% to 2%-the flow method, and the total amount can be within 5%. Limited by the lining material and materials of the measuring tube of the electromagnetic flowmeter, In the magnetic flowmeter pipe parts, a magnetic field, , and channeled into the liquid flowing through the pipe, Faraday’s Law states that the voltage generated is proportional to the movement of the flowing liquid, A conductor moving through a magnetic field produces an electric signal within the conductor. They must, to common ground lines such as motors and electrical appliances or to the upper and lower water pipes, through the cable, so do not ground again to avoid interference caused by different ground potentials, Installation Instructions for Electromagnetic Flowmeters - Sino-Inst. An electromagnetic flowmeter consists of two parts: Electrode (sensor) and Transmitter. The electromagnetic method measures the volume flow, which means the measurement is insensitive to changes in effects such as fluid density, temperature, pressure, and viscosity. In order to facilitate the installation, maintenance and maintenance, ample installation space is required around the flowmeter; The installation place of the electromagnetic flowmeter should avoid magnetic fields and strong vibration sources.
