How to choose integrated and split electromagnetic flowmeter?

Electromagnetic Flowmeter

It is a fully intelligent flowmeter developed by our company using the most advanced technology at home and abroad. It is widely used in industrial chemical fiber, food, paper, sugar, mining, metallurgy, water supply and drainage, environmental protection, water conservancy and hydraulic engineering, steel and other industrial fields. To measure the volumetric flow rate of various conductive liquid media such as acid and alkali, mud, pulp and the like. Its all-Chinese electromagnetic core converter uses a high-speed central processor. The calculation speed is very fast, the precision is high, and the measurement performance is reliable. The electromagnetic flowmeter sensor adopts a new technology of non-uniform magnetic field and a special magnetic circuit structure. The magnetic field is stable and reliable, and the volume is greatly reduced, the weight is reduced, and the flowmeter has the characteristics of small size and light weight.

1. There are no moving parts in the pipe, no flow blocking parts, and there is almost no additional pressure loss in the measurement.

2. The measurement results are independent of the flow velocity distribution, physical parameters such as fluid pressure, temperature, density, and viscosity.

3, high-definition backlight LCD display, full Chinese menu operation, easy to use, easy to operate, easy to learn and understand.

4, full digital processing, strong anti-interference ability, reliable measurement, high precision, flow measurement range up to 150:1.

5, with self-test and self-decision function.

Selection

Electromagnetic Flowmeter

It should be determined according to the physical and chemical properties of the conductive liquid medium to be tested. Important factors to be considered. The XD series electromagnetic flowmeter produced by Jiangsu Xianda Instrument needs to know the following parameters:

1,

Flowmeter diameter (DN);

2,

Flow range (maximum flow, minimum flow);

3,

Lining material / electrode material / output signal

The company's electromagnetic flowmeter installation is divided into two types, one is

One-piece electromagnetic flowmeter, one is a split type electromagnetic flowmeter, but how to choose an integrated electromagnetic flowmeter and a separate electromagnetic flowmeter in daily applications? Jiangsu Xianda Instrument Co., Ltd. teaches you the following:

1. Integrated electromagnetic flowmeter: Under the condition of good on-site and environment, generally, the integrated type is adopted, that is, the sensor and the converter are assembled into one.

2. Split type electromagnetic flowmeter: that is, the sensor and the converter are installed separately in different places, and the separation type is generally selected when the following conditions occur.

(1) The ambient temperature or the surface of the flowmeter converter is exposed to temperatures exceeding 60 °C.

(2) Where the pipe vibration is large.

(3) Where the aluminum casing of the sensor is seriously corroded.

(4) Where the site has high humidity or corrosive gas.

(5) The flowmeter is installed in an occasion where it is inconvenient to debug at high altitude or underground.

The distance between the sensor and the converter should be specified when ordering, generally not more than 100m, and the converter is installed on the wall.
