Guess you like: Magnetic flow meter working principle

There is a component in the structure of electromagnetic flowmeter called “electrode”. Where is the function of this electrode?

Let’s start with its principle. The measurement principle of electromagnetic flowmeter is based on Faraday’s law of electromagnetic induction.

When a medium with a certain conductivity flows through the measuring tube, it will cut the magnetic line of force to generate a certain electromotive force. The electromotive force is detected by the electrode and transmitted to the converter through the cable. After the converter processes the electromotive force, the flow rate of the medium can be displayed. .

The role of the electrode is to detect the magnitude of the electromotive force.

The magnitude of the electromotive force is proportional to the magnetic flux intensity. The inner diameter of the measuring tube is proportional to the average flow velocity. The volume flow of the medium is linearly related to the induced electromotive force and the inner diameter of the measuring tube. It is inversely proportional to the magnetic induction intensity of the magnetic field and has nothing to do with other physical parameters.

The electrode is in direct contact with the measured medium. Therefore, the selection of electrode material is very important. Commonly used electrode materials are 316L stainless steel, Hastelloy, titanium, tantalum, platinum, etc. The material of the electrode can be selected according to the characteristics of the medium.

Magnetic flow meters for wastewater

According to the situation of the wastewater treatment site, there are two general wastewater discharge methods. One is to discharge through pipes, and the other is to discharge through ditches. The two types of flow meters selected are therefore different.

1.Waste water is used for pipeline discharge, and most of them choose electromagnetic flowmeter to measure. Because there are no obstructions in the sensor, there is no fear of debris in the medium.

But need to pay attention to the medium must be full. If the pipe is not full, a pipe must be used to lead a section of the sinking pipe to ensure that the flowmeter is in a full pipe.

Note that the electromagnetic flowmeter cannot be installed at the drain of the pipeline, and the length of the straight pipe must meet the requirements of the flowmeter.

2.Wastewater is used for ditch discharge, mostly using ultrasonic open channel flow meters.

A measuring groove is installed at the discharge port, and an ultrasonic probe is installed directly above the groove. In this way, the flow of wastewater flowing through can be measured. This instrument generally uses 24V power supply, output: 4-20MA.

When selecting the electromagnetic flowmeter for waste water, it is necessary to know the temperature of the medium, the pressure of the medium, the flow range of the medium, the composition of the medium, the power supply requirements, and the on-site installation requirements. The key point of the selection is to choose which product to measure well. The second is to consider the convenience of installation, operation and maintenance. Finally, the product price can be considered.

Electromagnetic Flow Meter Price List

Why is the price of some lithium battery electromagnetic flowmeters at USD 0. Some prices are higher.

Some manufacturers quote real prices, and some quote false prices.
So many people will ask how much is a lithium battery electromagnetic flowmeter?

Electromagnetic flowmeters have different prices due to different diameters, different materials, different media, different linings, different meter heads, and different functions. The final quotation is based on the parameters.

Remarks:
Because the lithium battery electromagnetic flowmeter is battery-powered, the price is different than other ordinary electromagnetic flowmeters. The final price should be based on the parameters.

The flowmeter is for measurement, mainly for measuring flow. Accuracy is the main parameter of the flowmeter.

The flow sensor is a signal output. Electrical signal, pulse signal, which is usually called analog output. It is for flow control.

Portable flow meters can also be called portable ultrasonic flow meters.

Generally, due to the requirements of some industrial sites, the on-site environment cannot be satisfied for the pipeline installation method, which is not only troublesome to install, but also has many after-sales problems. Therefore, in many occasions, customers will choose portable ultrasonic flowmeters. Its convenient installation has won a lot of favored by customers.

Portable ultrasonic flowmeters are relatively powerful. For example, some have functions such as data storage, direct printing, and online analysis of data. The handheld ultrasonic flowmeter generally only meets the flow measurement function. If additional data processing is required, it can be processed in the form of data line transmission.

The flow coefficient of the turbine flowmeter is the flow rate that represents the on-site working conditions. The flow coefficient is usually precisely related to the measurement accuracy of the instrument. This is also a very important item. The measurement accuracy level of the turbine flowmeter can be ±1% and ±0.5%.

Ordinary water meters do not need to install batteries. Those with display screens need to install batteries. Those who do not need manual meter reading may also need batteries.

If the water meter is an ordinary water meter, that is, a rotor-type water meter, there is no need to install batteries. This water meter is mainly composed of a casing, an impeller measuring mechanism, a deceleration mechanism, and an indicator meter. It has the characteristics of simple structure.

If the water meter is an IC card prepaid water meter, a battery needs to be installed. Since its data transmission and transaction settlement are carried out through the IC card, it is possible to realize the change from the staff’s door-to-door meter reading to the user’s own payment at the business office. IC card transactions The system also has the characteristics of convenient transaction and accurate calculation. It can use the bank for settlement.
