Brand: Long RuiSi

Name: LDG divides the style electromagnetic flowmeter

Type:

About products:

LDG divides the style electromagnetic flowmeter and is used mainly for measuring various acid, volume flow of the medium that liquid or firm liquid of electric conduction such as alkali, salt solution, pulp, mud, water, sewage, beverage, drinks conduct each other.

The products are detailed:

LDG divides the style electromagnetic flowmeter and is made up of electromagnetic flow sensor and signal converter. Mainly ge, drinks and conducted used for measuring liquid or firm liquid of electric conduction such as various acid, alkali, salt solution, pulp, mud, water, sewage, beverage, drinks and conducted thed volume flow of the medium each other. Detection of the flow of trade of used in the chemical industry, mining and metallurgy, giving draining off water, dredging at the papermaking, sewage disposal, food, sugar refining, port extensively etc., accumulating calculating, regulating and controlling.

It is that our company produce LDG it last style electromagnetic flowmeter it precision high, before and after in charge of by sections of requirement low and not having long performance life at fault-free direct, the shelter grade with IP68, the suitable underground, moist and soaking and installing and using under the water environment.

It has the following characteristics that LDG divides the style electromagnetic flowmeter:

l It is greater than 5& mu to suitable for all conductive rate; Liquid of S/cm, body of thick liquid, the change of the electric conduction rate does not influence the performance measured;

l The sensor adopts and welds the structure wholly, the sealing is good, the shelter grade with IP68;

l Simple in construction and reliable, can’t move the mechanical part, do not almost have a pressure loss, very non-maintaining;

l In charge of small one section of requirements directly: Been in charge of section as internal diameter of 3- 5 times of pipelines directly ago, and then in charge of section as internal diameter of 2 times of pipelines directly;

l Users can expand or narrow and measure range according to the need, needn’t be again standard, can still guarantee the precision;

l Measuring the precision is not examined the influence that physical parameters such as medium pressure, temperature, density, viscosity,etc. change;

l Conductivity measures the function, can judge whether the sensor is empty managed automatically;

l Adopt 16 embedded microprocessors, the intellectual procedure signal is dealt with, operation is fast, the precision is high;

l Have two-way flow measure function, can reveal, reverse flow, percentage, velocity of flow;

l Can reveal, accumulate flow, accumulate flow backward forward separately, positive and negative to accumulate flow difference;

l Output signals proportional to flow: 4- 20mA, 0- 10mA, frequency output, the pulse is available in output;

l The communication function is available: RS232, RS485, convenient with getting on the location machine communication directly;

l The instrument is tall in sensitivity, almost have no district very much;

l Handle the function in function and trouble intelligence diagnosing;

l Operate menus Chinese and Englishly, the grade high and easy to use, apt to learn is apt to understand;

l Adopt electromagnetically to shield and protect the principle to design, the ability to resist interference is strong, measurement is steady, have not hindered the work longe-livedly.
