1、 Application scope of ARSLDE clamp sanitary electromagnetic flowmeter:
ARSLDE clamp electromagnetic flowmeter is mainly used in the food, pharmaceutical and other hygiene industries. Its process often requires long-term use of high-temperature steam for cleaning and disinfection to prevent bacterial growth. Therefore, the connection between pipelines and flowmeters in the hygiene industry generally uses quick couplings, namely clamp type structures.
2、 Principle of ARSLDE clamp sanitary electromagnetic flowmeter:
The ARSLDE clamp sanitary electromagnetic flowmeter is based on Faraday's law of electromagnetic induction: when a conductive liquid cuts magnetic field lines in a magnetic field, an induced potential is generated in the conductor, and the induced potential E is: E=KBVD, where:
K - Instrument constant
B -- Magnetic induction intensity
V - Average flow velocity
D - Inner diameter of pipeline
3、 Characteristics of ARSLDE clamp sanitary electromagnetic flowmeter:
1. The measurement of medium flow rate is not affected by changes in density, viscosity, temperature, pressure, and conductivity of the flow rate. The sensor induced voltage signal is linearly related to the average flow rate, resulting in high measurement accuracy
2. There is no obstruction in the measuring pipeline, so there is no additional pressure loss. There are no movable parts in the measuring pipeline, so the sensor has a long lifespan
3. The sensor of ARSLDE clamp sanitary electromagnetic flowmeter requires a short straight pipe section, which is convenient for installation
4. The sensor part of the ARSLDE clamp sanitary electromagnetic flowmeter only has the inner lining and electrode in contact with the measured liquid. As long as the electrode and inner lining materials are selected reasonably, they can resist corrosion and wear
5. A bidirectional measurement system that can measure both forward and reverse flow rates.
4、 Advantages and unique selling points of ARSLDE clamp sanitary electromagnetic flowmeter product:
1. The most important component of the ARSLDE clamp sanitary electromagnetic flowmeter sensor - the coil - is optimized in design and undergoes the strictest real flow test to ensure the measurement accuracy of the product
2. The signal electrode undergoes thorough electrostatic shielding treatment to ensure that small signals are not interfered by the coil and to guarantee measurement accuracy at low flow rates
3. The coil is isolated from the outside world to ensure its long-term insulation strength, which in turn guarantees the long-term measurement accuracy of the sensor
4. All welding processes for the sensor of ARSLDE clamp sanitary electromagnetic flowmeter are carried out using argon arc welding technology. Although the cost is high, it can ensure the reliability of welding (welding is the main production process of the sensor), especially the last welding process after installing the coil. Using argon arc welding technology can ensure that the installed coil is not damaged
5. Adopting a grounding electrode structure to form a balanced electrode plane ensures that the entire process of measuring the average speed is limited to the balanced electrode plane, which can effectively eliminate electrical noise interference and provide accurate measurement results
