1. Electromagnetic flowmeter | mfe4515110a105-s | 0~10000m/h | 0.5 level

Based on the model and parameters you provide, this electromagnetic flowmeter is suitable for high-precision flow measurement scenarios with large pipe diameters, and is typically used in water conservancy projects, large-scale chemical processes, or municipal water supply metering. 1. Core parameter analysis model identification: MFEA105-S usually indicates a nominal diameter of DN450 (or similar specifications), and S may represent a backup stainless steel material or special protection level. Measurement range: 0-10000 m ³/h corresponds to a flow rate of about 0.35-17.5 m/s (estimated based on DN500 pipe diameter). Accuracy level: Level 0.5 indicates a measurement error of ≤± 0.5%, belonging to industrial grade high-precision instruments Technical features: Low frequency rectangular wave excitation technology is adopted, with strong anti-interference ability. The minimum conductivity requirement is ≤ 5 μ S/cm (more than 20 times the standard water quality). The pressure loss is almost zero (only the resistance of the pipeline itself). The working pressure is usually ≤ 1.6MPa (it needs to be confirmed that the flange or other orange width level) Installation requirements • Front and rear circular bright straight pipe section requirements: Front 10DN and rear 5DN (DN is the pipe diameter) • Full pipe installation is required, and it is recommended to install vertically from bottom to top • The grounding ring must be reliably grounded with a grounding resistance of less than 4 Ω • Avoid strong electromagnetic interference sources (such as high-power frequency converters) 4 Application limitations • Cannot measure gases, vapors, or liquids

2. What should I do if the displayed value of the flowmeter fluctuates greatly and is not accurate?

First, check for non fault fluctuations, and then deal with hardware or calibration issues accordingly. Most of them can quickly solve the problem of inaccurate flowmeter # # 1 First, confirm whether it is a non fault fluctuation. Often, large numerical fluctuations are not caused by damage to the flowmeter itself, but by external environmental factors. 1. Unstable medium flow: for example, there are air pockets in the pipeline, pump start stop fluctuations, and frequent valve opening and closing, which can cause significant fluctuations in instantaneous flow. You can observe whether there are abnormal noises or bubbles in the pipeline and try to stabilize the upstream feed/liquid pressure Improper installation position: The flowmeter is installed near the pump outlet, elbow, and valve, which may be affected by fluid disturbance. It is recommended to move it to a straight section of the pipeline and reserve at least 5 times the diameter of the pipe for installation Power supply/signal interference: If electromagnetic flow meters and turbine flow meters are close to s
