How can I make the data of the flow meter larger?

According to the working principle, it can be divided into the following types: l rotameter l gas mass flowmeter l turbine flowmeter l ultrasonic flowmeter l electromagnetic flowmeter l vortex flowmeter l volumetric flowmeter l differential pressure flowmeter and the rotameter in your picture is a rotameter: called a float flowmeter, and its flow detection element is composed of a vertical conical tube that expands from the bottom to the top and a float that moves up and down along the shaft of the cone.

When the measured fluid passes through the annular gap formed by the cone tube and the float from the bottom up, the force of the float rising is formed. When the lifting force is equal to the weight of the float immersed in the fluid, the float stabilizes at a certain height. This height value is the flow value of the fluid.

Processed on a case-by-case basis. Electromagnetic flowmeter.

The measuring principle is based on Faraday's law of electromagnetic induction.

After using the electromagnetic flowmeter for a period of time, it will sometimes be found that the electromagnetic flowmeter has no medium flowing in the pipeline, and the electromagnetic flowmeter will also have instantaneous flow values in the case, so how to deal with this situation is what the user must know, and there are many reasons for this problem, first of all, it is necessary to exclude whether the electrode is polluted, whether the electromagnetic flowmeter sensor is damaged and whether the flow zero point of the electromagnetic flowmeter is normal, etc., and the specific elimination method is:

Check that the fluid medium in the process piping is filled with pipes.

Check whether the flow rate of the fluid through the pipeline is normal in the process.

If the electrode is contaminated, clean the electrode and check whether the electrode is damaged.

Check the electromagnetic flowmeter sensor.

To adjust the flow zero point of the flow meter, the specific steps are as follows:

Fill the pipe of the electromagnetic flowmeter with medium (must be a metal pipe), close the valves at both ends of the electromagnetic flowmeter, and make the medium in the pipeline in a full and stationary state.

Enter the electromagnetic flowmeter converter menu, refer to the electromagnetic flowmeter instruction manual to check whether the content of each menu meets the initial setting (it cannot be ruled out that the electromagnetic flowmeter will be adjusted by other personnel in use), and correct the zero point of the flow rate to .

After the zero point is corrected, observe whether the instantaneous flow rate is zero and no longer changes.

If there is no problem with the above inspections, the electromagnetic flowmeter will generally be returned to the factory for inspection and maintenance.

Flowmeter, adjust the bottom probe, into the signal, will make the data larger.

There is no other way to adjust the parameters.

The method of modifying the flow rate under real working conditions, when the instantaneous flow rate of the current electromagnetic flowmeter is Q1 and the K coefficient is K1, when the actual desired flow rate is Q2, it is necessary to modify the value of the current K coefficient K2 and adjust the current one.

Flow rate, can be achieved by modifying the current k coefficient, assuming that the new k coefficient value is k2, k2 is equal to the actual desired flow rate q2 divided by the instantaneous flow rate q1, multiplied by the current k coefficient k1, i.e., k2=

q2/q1)*k1

For example, the electromagnetic flowmeter shows that the current instantaneous flow rate is Q1=, and the instrument coefficient K1= is set inside the electromagnetic flowmeter, and the actual flow rate Q2= can be verified according to field experience or other methods, then the actual desired flow rate can be obtained by modifying K1

That is: k2=(q2 q1)*k1=(, the obtained k2 will be re-set to the column of the meter coefficient of the electromagnetic flowmeter, replacing the original k1, and the new instantaneous flow q2 will be obtained.

You didn't specify what type of flow meter it is?

This cannot be adjusted solely on the basis of a single point of data, but must be adjusted from the entire range.

This is to be adjusted in the range, for example, the corresponding flow range of 4-20mA is 0-100L min, which is to be set.

The flowmeter is connected to the computer through the RS485 line, and then connected to the computer through the RS485 to RS232 converter, and then the test configuration software is set. The converter can be done for 500 yuan. But this can only receive 485 signals, can not collect 4 20mA current signals, 4 20mA requires a special capture card to convert to 485.

485 is the current instantaneous and cumulative amount of the reading data. 4 20mA is just a signal that indicates the instantaneous flow rate, and it needs to be accumulated by the computer software itself.

Install 360 Security Guard, with traffic monitoring.

Select the PID control regulator.

What you actually have to solve is to control the temperature of the water, right? You can monitor the effluent temperature to control the amount of steam, which is usually the case. Fluctuating steam flow is a problem with your system.

I don't know what you mean. What do you want to do with this?

Yes, there are many ways, but that kind of data is inaccurate.

It depends on what kind of parameters you choose the mass flow meter, if it is intelligent, it can be achieved through computer software, and the table itself also has a setting button, Sieea brand, imported from the United States, the quality is good, but it is not cheap.

With the help of a communicator (see what protocols are supported, there are usually HART, Honeywell, etc.) or a computer. Or change it directly on the flow meter.

Take a look at the gauge. Whether it is caused by electromagnetic interference.
