How does an electromagnetic flowmeter read?

Electromagnetic flowmeter is a commonly used flow measurement instrument, which calculates the flow rate by measuring the electromagnetic induction of liquid in a magnetic field. When using an electromagnetic flowmeter, it is necessary to read it. Below is an introduction to the reading method of an electromagnetic flowmeter. 1. Reading instantaneous flow electromagnetic flowmeter can measure instantaneous flow in real time. The reading method is as follows:

(1) Open the display screen of the electromagnetic flowmeter and observe the instantaneous flow value on the screen.

(2) If you need to record instantaneous flow data, you can record the data in a recorder or computer

2. Read the cumulative flow. The electromagnetic flowmeter can also measure the cumulative flow. The reading method is as follows:

(1) Open the display screen of the electromagnetic flowmeter and observe the cumulative flow value on the screen.

(2) If you need to record cumulative flow data, you can record the data in a recorder or computer

3. Reading the flow velocity. Electromagnetic flowmeter can measure the flow velocity of liquid, and the reading method is as follows:

(1) Open the display screen of the electromagnetic flowmeter and observe the flow velocity value on the screen.

(2) If you need to record flow rate data, you can record the data in a recorder or computer

4. Reading the liquid level. The electromagnetic flowmeter can also measure the liquid level. The reading method is as follows:

(1) Open the display screen of the electromagnetic flowmeter and observe the liquid level value on the screen.

2. How to choose the material of electromagnetic flowmeter?

Tianjin Xuner Instrument answers for you: As a commonly used flow measurement instrument, the selection of material for electromagnetic flowmeter is also an important factor. Due to the fact that only the electrode and the interior of the measuring tube are in contact with the medium in the electromagnetic flowmeter, it is necessary to select the correct electrode and lining material according to the characteristics of different media.

1. Selection of electrode materials 1 Stainless steel (0Cr18Ni12Mo2Ti). Suitable for nitric acid, sulfuric acid with less than 5% at room temperature, boiling phosphoric acid, formic acid, alkaline solutions, sulfite under certain pressure, seawater, acetic acid. 2. Hastelloy B and Hastelloy C. Can be used for seawater and saltwater. 3. Titanium. Suitable for seawater, various chlorides and hypochlorous hydrochloric acid, oxidizing acids (including fuming nitric acid), organic acids, bases, etc. 4. Tantalum. Other chemical media, including boiling point hydrochloric acid, nitric acid, and sulfuric acid below 175 ℃, can be used except for hydrofluoric acid, fuming sulfuric acid, and alkali. 5. Platinum. Can be used for various acids, bases, and salts, but does not include aqua regia.

2. Selection of lining material 1 Rubber. It has excell
