Flow meter

The inlet of the piping system of the process industry is often connected to a container or a high-level tank, and the inlet of a public utility piping system is often connected to a pool or a river channel. The inlet must have a distance of 2-5 times the diameter of the inlet pipe below […]

The liquid flowing in the pipe may be mixed with air bubbles due to various reasons. For example, if the flow sensor is installed horizontally at the high or second high point of the piping system, it is easy to accumulate on the upper part of the horizontal pipeline and the flow sensor measuring tube,

The degree of influence of the magnetic field on the electromagnetic flow sensor varies greatly depending on the structural material and design of the sensor protective housing. For example, some shells are made of ferromagnetic materials such as steel plates, which have a better magnetic shielding effect and have less impact; others are made of

Material Performance characteristics Applicable fluid Precautions Overall 1. The inner surface is smooth, and it is not easy to adhere to the deposited layer 2. Superior corrosion resistance 3. Wide fluid temperature range 1. High permeability liquids such as hydrofluoric acid, hydrochloric acid, and acetic acid 2. Sulfuric acid, caustic soda, electrolyte, and other strong

The liquid flow rate of the electromagnetic flowmeter at full-scale flow can be selected within 0.5-10m/s, and the range is relatively wide. The upper limit flow rate is not limited in principle due to the small resistance loss of the instrument. However, it is generally recommended not to exceed 5m/s, unless the material in the

The performance of general-purpose electromagnetic flowmeters on the market is quite different. Some have high accuracy and many functions; some have low accuracy and simple functions. The accuracy grades of high-precision instruments are 0.5 and 1, the basic error is usually ±(0.5-1)%R, and the low-precision instruments are ±(1.5-2.5)%FS. Some models of instruments claim that the

We call the electromagnetic flow sensor used for measuring closed pipes filled with the fluid medium as general-purpose sensors. The general sensor product caliber can range from 1mm to 3m. Such a wide range of different calibers brings some differences in the structure and performance of the flowmeter, and the difference in performance is mainly

The theory of electromagnetic field tells us: alternating electric field can produce an alternating magnetic field, the alternating magnetic field can produce an alternating electric field, alternating electric field and magnetic field are always interconnected and mutually converted. Part of the main magnetic flux in the sensor forms a closed eddy current streamline with orthogonal

The DC excitation mentioned here includes a constant magnetic field using a permanent magnet and a constant magnetic field excited by a DC current. However, the DC signal voltage induced by the use of a DC magnetic field can easily polarize the electrolyte liquid flowing through the measuring tube, and the resultant signal obtained on

(1) Digital signal output The output of the turbine flowmeter is a pulse digital signal proportional to the flow rate. The advantages are easy to accumulate and easy to send into the computer system. Pulse output type: ①-General working voltage: +12VDC or +24VDC two kinds (the power supply must be selected before ordering). ②Signal transmission
