1. Main parameters and adjustment methods of electromagnetic flowmeter
The main parameters and adjustment methods of electromagnetic flowmeter include electrode distance, magnetic circuit length, electrode inner diameter, and electrode angle, etc. The following is a detailed explanation and adjustment method for these parameters:
1. Main parameter electrode distance definition: electrode distance refers to the straight-line distance between two electrodes in an electromagnetic flowmeter. Importance: The distance between electrodes is closely related to measurement accuracy, as it directly affects the strength and stability of electromagnetic induction signals. Adjustment principle: Generally, the distance between the sock and stool electrodes should be determined based on the conductivity of the medium. For media with high conductivity, a smaller electrode distance can be chosen; For media with low conductivity, a larger electrode distance is required to ensure sufficient signal strength. Definition of magnetic circuit length: Magnetic circuit length refers to the length of the magnetic field through which the liquid flows through the sensor. Importance: Optimizing the length of the magnetic circuit can improve the strength and stability of the electromagnetic field, thereby affecting measurement accuracy. Adjustment principle: On the premise of ensuring sufficient magnetic field strength, the length of the magnetic circuit should be as short as possible to reduce energy loss and interference. At the same time, the adjustment of magnetic circuit length also needs to consider the flow velocity and flow range of the medium. Definition of electrode inner diameter: The electrode inner diameter refers to the
2. Adjustment Method: The process of adjusting electrode distance: Firstly, select the appropriate electrode distance range based on the conductivity of the medium;
; Then, change the electrode distance by adjusting the installation position of the electrode; Finally, use a calibration device for calibration to ensure measurement accuracy. Attention: When adjusting the electrode distance, ensure good insulation performance between the electrodes to avoid short circuits or leakage. The adjustment process of magnetic circuit length: Firstly, determine the appropriate magnetic circuit length based on the flow velocity and flow range of the medium; Then, adjust
