Instrument selection and installation of industrial circulating cooling water treatment facilities

Abstract: the industrial circulating cooling water treatment facilities instrument selection and installation of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. The production of industrial circulating cooling water treatment facilities as the main lifeline, the normal operation of the circulating water treatment facilities for the main process of normal production and protect the safety of the equipment plays an important role. And every link of water treatment is always with the corresponding apparatus. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the industrial circulating cooling water treatment facilities instrument selection and installation of the article details. The production of industrial circulating cooling water treatment facilities as the main lifeline, the normal operation of the circulating water treatment facilities for the main process of normal production and protect the safety of the equipment plays an important role. And every link of water treatment is always related to the corresponding instruments and automatic control technology. Instrument for testing the water system parameters, and according to these parameters for manual or automatic control, coordination between the supply and demand, system between each component, the relationship between the various water treatment processes, so that all kinds of equipment and facilities to get more fully, the reasonable use; At the same time, the instrument measuring value comparing with set point can be continuous, deviation occurs, immediately adjusted, so as to ensure the quality of water treatment. The instrument also has the function of continuous testing, the limit alarm to facilitate processing accident, also is the basic condition of the computer control. So the automation instrument in the industrial circulating cooling water treatment facilities has a very important role. Industrial circulating water treatment facilities commonly used instrument with liquid level meter, flow meter, thermometer, pressure gauge, conductivity meter, etc. In this paper, the selection and installation of the instrument are analyzed and discussed, which can be taken as reference to the practical engineering. 2 circulating water treatment facilities in all sorts of commonly used instrument selection 2. 1 level of level gauge has connectors commonly used type, floating ball type magnetic flip level gauge, ultrasonic level meter, radar level gauge, etc. The principle, characteristics and application scope of level gauge are as follows. （ 1) Connectors type level gauge principle: the common glass tube liquid level meter. Features: simple structure, low price, intuitive, suitable for field use, but easy to damage, the inner surface easily infected with dirt, reading difficulties, not to facilitate remote transmission and regulation. （ 2) Principle: ball float liquid level gauge in a liquid into a hollow float ball, when the liquid level change, floating ball will produce the same displacement with the liquid level changes, mechanical or electrical methods are available to measure displacement of floating ball. Characteristics: precision & plusmn; （ 1 ~ 2) %, the outputs are switch control and continuous output. Simple structure, low price, it is not suitable for high viscosity fluid. （ 3) Ultrasonic level meter principle: use of ultrasonic attenuation in gas, liquid, penetrating power harmonic impedance characteristics of different measuring the interface of two kinds of medium and features: for precision & plusmn; 0. 5%. Such instrument of high precision, fast response, no mechanical moving parts, high reliability, installation is simple, convenient, belong to the non-contact measurement, and is not affected by the liquid viscosity, density, etc, but the cost is high, the maintenance difficulty. （ 4) Magnetic flip the level principle: by magnetic indicator and floating ball of two parts. Magnetic indicator from the red and white with small magnets magnetic column and plate, etc. Equipped with magnetic steel floating ball move up and down with the liquid, the floating ball in * magnetic beam of magnetic double column will flip 180 & deg; , liquid level rises, the column from white to red, the liquid level falls, double column from red to white, which indicates that the liquid surface height. When need analog output, install a parallel to the magnetic reed tube transmitter, indicator can achieve 4 ~ 20 ma, or 0 ~ 10 ma current signal transmission; With liquid level alarm switch, also can realize alarm level of the upper and lower limits. Features: in addition to the instructions, but also with remote transmitter, alarm, switches, control switches, testing the function is all ready. Indicating novel, intuitive reading and eye-catching. Indicating device and is completely isolated measured medium, good sealing, high reliability, the use of safe. Simple structure, convenient installation, low maintenance cost. Corrosion resistance, without power, explosion-proof. （ 5) The basic principle of radar level gauge and ultrasonic liquid level meter. Features: high precision, reliability is high, easy to use, but higher than the ultrasonic level meter.

Everyone who has a coriolis mass flow meter emerson wants it to look coriolis density meter. However, in order to achieve that, it normally involves investing in a tuning fork liquid density meter mass flow meter. Beijing Sincerity Automatic Equipment Co., Ltd can offer you the best solution.
