Characteristics of tube electromagnetic flowmeter
Pipeline electromagnetic flowmeter has the characteristics of accuracy, low functional consumption and strong measurement effect, mainly measuring the flow of conductive fiber fluid in tap water, steel, petroleum, chemical industry, electric industry, industry, water conservancy, water administration and water resources.
Then the price under the characteristics of the pipeline electromagnetic flowmeter and installation
1. The tube electromagnetic flowmeter is a velocity electromagnetic flowmeter based on Faraday's law of electromagnetic induction.On the basis of describing the measurement principle of electromagnetic flowmeter, an LDB electromagnetic flowmeter based on MSP430F149 microcontroller is designed. The circuit principle is based on MSP430F149 microcontroller, so as to simplify the design of peripheral computer hardware circuit principle and realize the measurement and accumulation of liquid flow.
2, the electromagnetic flowmeter can be required to avoid strong power equipment, high frequency equipment, strong power switch equipment;Must avoid the influence of high temperature heat source and radiation source, must avoid strong vibration place and strong corrosion environment, etc., at the same time to consider the installation and maintenance convenience.
3. The tube electromagnetic flowmeter has the functions of saving the flow data trend, power failure time, zero flow time and other data trends for 24 hours a day, as well as alarm.Every day, just one or two short messages can get a measurement point 24 hours a day in the measurement data trend, it can also change according to the user's needs.Using the technology of combining the electromagnetic vortex flowmeter with GSM network, the initial investment of establishing the water flow monitoring system is only 1/3 to 1/5 of that of the radio station, and the operating cost after the establishment of the system is only the cost of one or two short messages per point per day.The usage fee of frequency and electricity charge and maintenance cost are saved.
4. The display, communication and data storage of the flow detection instrument are important components of the instrument.The traditional electromagnetic flowmeter USES LED or segment LCD in the display mode, which can only display Numbers, letters, Chinese characters and some rough patterns.In terms of data storage, information storage is generally stored in binary mode, which is not universal and has a small storage capacity.In terms of communication mode, RS232 or RS485 is generally adopted, and its openness is not high.
5. Installation of sensor in vertical pipeline when measuring gas flow, the sensor can be installed in vertical pipeline with unlimited flow direction.If the measured gas contains a small amount of liquid, the flow of the gas should be downward and upward.When measuring the flow of liquid, the liquid should flow from the bottom up: this will not attach the weight of the liquid to the probe.
6. The sensor is mounted on the side of the horizontal pipe. No matter what kind of fluid is being measured, the sensor can be mounted on the side of the horizontal pipe.
7. This installation method is not recommended for the inversion of horizontal pipelines.This installation method is not suitable for measuring general gas, superheated steam, but can be used for measuring saturated steam, suitable for measuring high temperature liquid or frequently cleaning pipes.
Shanghai China xi instrument co., ltd. introduced Germany Siemens CNC machining center, so that the micro flowmeter greatly improved, in fact has reached the world's leading level, such as many customers with Japan O
