2. Improve the reliability of the instrument.
application
Magnetic Flowmeters are used for measuring and controlling industrial and agricultural flow in industries such as petrochemicals, steel metallurgy, water supply and drainage, irrigation, water treatment, sewage treatment plants (environmental sewage control, chemical sewage, electroplating sewage), papermaking (pulp), mud, medicine, food, etc.
Common question Q1: Can the electromagnetic flowmeter have perfect accuracy?
A1: In an ideal situation, the flow reading of the process instrument will be completely correct without any type of deviation. Unfortunately, this is not the case, and inherent errors in measurements must always be identified, considered, and minimized as much as possible.
Q2: Does the electromagnetic flowmeter need calibration?
A2: In the production process of Flowmeters, several steps are required, such as coil winding, lining processing, and electrode assembly. This series of operations will cause a certain degree of error and dispersion in the equipment, so a calibration process is needed to correct the accuracy.
Q3: How often does an electromagnetic flowmeter need to be calibrated?
A3: Magnetic recalibration of Flowmeter every two years (every two years) or at the manufacturer's specified low frequency. The readings of the small frequency meter specified by the manufacturer are pressure corrected and moisture content corrected if necessary.
Kind reminder: What is an electromagnetic flowmeter?
A magnetic flowmeter or electromagnetic flowmeter is an instrument based on the principle of electromagnetic induction, which measures the flow rate of a conductive fluid by generating an electric potential through an external magnetic field. The structure of an electromagnetic flowmeter mainly consists of a magnetic circuit system, measuring tube, electrode, housing, lining, converter, etc.
