Anti corrosion special flowmeterJob Introduction:

CS-LDE-1804Anti corrosion special flowmeterIt is a measurement based on Faraday's law of electromagnetic induction. The flowmeter can not only meet the on-site display requirements, but also output 4-20mA current signals for recording, adjustment, and control purposes,Electromagnetic flow meters have a wide range of applications. Large caliber instruments are commonly used in water supply and drainage engineering, while small and medium-sized instruments are commonly used in solid-liquid two-phase difficult to measure fluids or high demand places, such as measuring pulp and black liquor in the paper industry, slurry in the non-ferrous metallurgy industry, coal slurry in the coal preparation plant, highly corrosive liquids in the chemical industry, and controlling and monitoring cooling water in blast furnace tuyere in the steel industry. Flow measurement and control of long-distance pipeline coal hydraulic transportation. Small caliber and micro caliber are commonly used in places with hygiene requirements such as the pharmaceutical industry, food industry, and biotechnology.Changshun LDE seriesIn addition to measuring the flow rate of general conductive liquids, sulfuric acid flow meters can also measure the volumetric flow rate of liquid-solid two-phase flow, high viscosity liquid flow, and salt, strong acid, and strong alkali liquids.

Anti corrosion special flowmeterAdvantages and unique selling points:

1. The component of the sensor - the coil - is designed and rigorously tested 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 of the sensor are carried out using argon arc welding technology. Although the cost is high, it can ensure the reliability of welding (welding is the most important 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
