Plug-in electromagnetic flowmeter
The measurement principle of the plug-in electromagnetic flowmeter is Faraday's law of electromagnetic induction. The main components of the plug-in electromagnetic flowmeter sensor are: measuring tube, electrode, excitation coil, iron core and yoke shell. The plug-in electromagnetic flowmeter is mainly used to measure the volume flow of conductive liquid and slurry in closed pipelines. Including acid, alkali, salt and other highly corrosive liquids. Plug-in electromagnetic flowmeters are widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries, as well as environmental protection, municipal management, water conservancy construction and other fields.
1, the measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity;
2, there are no obstructive flow parts in the measuring pipe, no pressure loss, and the straight pipe section requires lower requirements;
3, series nominal diameter DN15～DN3000. There are many options for sensor lining and electrode materials;
4. The converter adopts a new excitation method with low power consumption, stable zero point and high accuracy. Flow range degree 1500:1;
5. The converter and the sensor can be integrated or separated;
6. The converter adopts 16-bit high-performance microprocessor, 2x16LCD display, convenient parameter setting and reliable programming;
7. The flowmeter is a two-way measurement system with three totalizers: forward total, reverse total and difference total; it can display positive and negative flow, and has multiple outputs: current, pulse, digital Communication, HART;
8, the converter adopts surface mount technology (SMT), with self-check and self-diagnosis functions
The plug-in electromagnetic flowmeter is composed of a plug-in electromagnetic flow sensor (sensor for short) and an electromagnetic flow converter (converter for short) (referred to as flowmeter). It is an instrument used to measure the volume flow of various conductive liquids in the pipeline.
Plug-in electromagnetic flowmeter is used to measure the flow of conductive fluid in tap water, steel, petroleum, chemical, electric power, industry, water conservancy and other sectors, and it can also measure corrosive conductive liquids such as acids, alkalis, and salts.
Corrosion-resistant all stainless steel material ABS full mold production probe The structure is simple, firm, without moving parts, and long service life:
Reliable measurement, strong anti-interference ability;
Small size, light weight, convenient installation, low maintenance;
Large measurement range, the measurement is not affected by changes in temperature, density, pressure, viscosity, conductivity, etc.;
The pressure loss is zero;
It can be installed and disassembled under the condition of continuous flow, which brings convenience to the user's maintenance.
Compared with the general electromagnetic flowmeter, the manufacturing cost and installation cost are lower, and it is suitable for the flow measurement of large and medium-diameter pipelines.
