| TC-ZNDC intelligent electromagnetic flowmeter | TC-ZNDC intelligent electromagnetic flowmeter is a fully intelligent flowmeter developed and developed by our company using the latest advanced technology at home and abroad. It is very different from old-fashioned analog or non-intelligent electromagnetic flowmeters, especially in measurement accuracy and reliability. , Stability, use function and service life.
TC-ZNDC electromagnetic flowmeter is a flow meter with high accuracy, high reliability and long service life, so we are very careful about every link in the process of designing product structure, selecting materials, formulating processes, production assembly and factory testing, we We also designed a set of domestically most advanced production equipment and flow calibration equipment dedicated to electromagnetic flowmeters, so as to ensure the long-term high quality of the product in both software and hardware.
TC-ZNDC intelligent electromagnetic flowmeter has specially designed a Chinese LCD display with backlight and wide temperature, which is complete and practical, intuitive to display, and easy to use, which can reduce the inconvenience caused by the English menu of other electromagnetic flowmeters. In addition, our exclusive design of 4-6 multi-electrode structure further guarantees measurement accuracy and does not require a grounding ring at any time, reducing the volume of the instrument and the trouble of installation and maintenance.
Flow measurement is not affected by changes in the density, viscosity, temperature, pressure, and conductivity of the fluid. The sensor's induced voltage signal has a linear relationship with the average flow rate, so the measurement accuracy is high.
There is no obstruction in the measuring pipe, so there is no additional pressure loss ; there are no moving parts in the measuring pipe, so the life of the sensor is extremely long.
Since the induced voltage signal is formed in the entire magnetic field-filled space and is the average value on the pipeline loading surface, the straight pipe section required by the sensor is shorter and the pipe diameter is 5 times the length.
The sensor part only has the lining and the electrode in contact with the liquid to be measured. As long as the electrode and lining materials are reasonably selected, they can be resistant to corrosion and wear.
The converter adopts the latest and most advanced single-chip microcomputer (MCU) and surface mount technology (SMT) , which has reliable performance, high accuracy, low power consumption, stable zero point and convenient parameter setting. Click the Chinese display LCD to display the accumulated flow, instantaneous flow, flow rate, flow percentage, etc.
Two-way measurement system can measure forward flow and reverse flow. Special production technology and high-quality materials are used to ensure that the performance of the product remains stable for a long time.
Intelligent electromagnetic flowmeter
Intelligent electromagnetic flowmeter is suitable for measuring the volume flow of conductive liquids and slurries in closed pipelines , such as strong corrosive liquids such as acids, alkalis, salts, raw water, cooling water, pulp, slurry, coal slurry, ore slurry, syrup, corn slurry, fiber slurry , Grain slurry, lime milk, hydrogen peroxide, sea water, beer, wort, milk and various beverages and other conductive liquids and solid-liquid two-phase liquids .
The measuring principle of the TC-ZNDC intelligent electromagnetic flowmeter is based on Faraday's law of electromagnetic induction : When a conductive liquid performs cutting magnetic field lines in a magnetic field, an induced potential is generated in the conductor, and its induced potential E is :
E = KBVD
In the formula : K ----- instrument constant
B ----- magnetic induction
V ----- Measure the average flow velocity in the section of the pipeline
D ----- Measure the inner diameter of the pipe section
When measuring the flow rate, the conductive liquid flows at a velocity V through a magnetic field perpendicular to the direction of flow. The flow of the conductive liquid induces a voltage proportional to the average flow velocity, and the induced voltage signal directly contacts the liquid through two or more The electrodes are detected and sent to the converter through the cable for intelligent processing, and then the LCD displays or converts them into standard signals of 4 to 20 mA and 0 to 1 kHz output.
