1. Insertion electromagnetic flowmeter is a flow measurement instrument based on Faraday's law of electromagnetic induction, mainly used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines.

Here is a detailed introduction:

■Working Principle:

In an electromagnetic flowmeter, the conductive medium inside the measuring tube is equivalent to a conductive metal rod in Faraday's test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows through, it will cut the magnetic induction line and generate an induced voltage. The two electrodes inside the pipeline are used to measure this induced voltage, and the flow rate of the fluid is calculated by measuring the magnitude of the induced voltage.

■Main components:

Composed of a plug-in electromagnetic flow sensor and a plug-in electromagnetic flow converter, the sensor includes components such as a measuring tube, electrodes, excitation coil, iron core, and magnetic yoke housing. The converter is responsible for processing and converting the signals detected by the sensor.

■Product Features:

1. High measurement accuracy:

The measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity, and can provide high-precision measurements in both directions with good repeatability.

2. Small pressure loss:

The measuring tube has no obstructed flow components, no pressure loss, and low requirements for straight pipe sections.

3. Wide applicability:

The series has a nominal diameter of DN80-DN3000, and there are multiple options for sensor lining and electrode materials. It can measure highly corrosive liquids such as acids, alkalis, and salts, and is widely used in various industries such as petroleum, chemical, and metallurgy. 4. Rich functions: The converter can be integrated or separated with sensors, using high-performance microprocessors, LCD display, convenient parameter setting, reliable programming, can display positive and negative flow rates, and has multiple output modes.

5. Easy installation and maintenance:

It can be installed and disassembled without interruption. The probe is made of corrosion-resistant all stainless steel material and ABS full mold production. It has a simple and sturdy structure, no moving parts, long service life, and low maintenance.

6. Installation requirements:

To ensure measurement accuracy, it is necessary to ensure sufficient front and rear straight pipe sections. When installed at the rear end of the T-shaped pipe, the electromagnetic flowmeter and T-shaped pipe need to ensure a minimum of straight pipe sections of 20D in the front and 10D in the back; When installed at the rear end of a 90 ° bend, a minimum of 10D and 5D straight pipe sections should be ensured at the end of the bend; Installed at the back end of the valve and not fully open, a minimum of 20D of straight pipe section must be ensured between the valve and the back end.
