Datasheet Electromagnetic flow meter for flow measurement SUP-LDG-DNXX flow meter Supmea's electromagnetic flow meter does not contain any moving parts, rotating gears or turbines, or bearings. Instead, it relies on two electrodes to measure the density of the induced magnetic field that results from an electrically conductive fluid, such as water, flowing through a pipe. So there is no susceptibility to bearing wear or other mechanical wear-and-tear issues. As for the electrodes and the liner used in electromagnetic flow meter, these components can be fabricated from a variety of materials...

Principle The measurement principle of magnetic flowmeters can be described as follows: when the liquid goes through the pipe at the flow rate of v with a diameter D, within which a magnetic flux density of B is created by an exciting coil, the following electromotive E is generated in proportion to flow speed v: E=K×B×V×D Where: E-Induced electromotive force K-Meter constant B-Magnetic induction density V-Average flow speed in cross-section of measuring tube D-Inner diameter of measuring tube The induced voltage signal is detected by two electrodes and transmitted to the converter via a...

Parameter ★ Process connection Clamp on (Stainless steel) Flange (Stainless steel) Flange (Carbon steel) ★ Location Do not install the electromagnetic flowmeter on a free-vibrating pipe without any support. Instead, a mounting base shall be used to secure the measuring tube. When the electromagnetic flowmeter is required to be installed underground, the pipes at both inlet and outlet ends shall be provided with support items, and a metal protection plate shall be installed above the flowmeter.

(1) No bubbles shall be observed in the pipes. (3) The electromagnetic flowmeter cannot be installed Pipes shall be designed to prevent the air bubbles in the on the suction side of the pump fluids from accumulating the measurement pipe of a sensor. If a valve exists near the flowmeter, try to mount the flowmeter on the valve’s upstream side for preventing a decrease of pressure inside the pipe possibly, consequently avoiding the possibility of air bubbles. ensure that no gas can be separated from the liquid. (4) For long pipelines, control valves are generally installed on the downstream...

(7) Measurement error caused by incidental gas and damage of lining caused by vacuum shall be avoided As the voltage of induced signal of electromagnetic flowmeter is small, it’s more prone to be affected by noises or other electromagnetic signals. This is why the electromagnetic flowmeter needs to be grounded in many occasions. This functions to form an internal space for shielding external interference through the grounding of flowmeter casing, thereby improving measurement accuracy.
