KOBOLD flowmeter spot model VKG-2105UOR15

KOBOLD flowmeter spot model VKG-2105UOR15，This model was ordered by the German company in the wrong quantity. There is one extra stock in the company's inventory, and it needs to be shipped directly on the same day.

During the use of KOBOLD flowmeter, attention should be paid to whether the set working parameters have changed, and whether the displayed flow rate, density, and temperature values are normal. If there is a significant deviation from the actual values, zero flow calibration can be performed again according to the method described in the user manual. If you still feel abnormal after completing the above work, you should check whether the various working parameters set inside the transmitter are correct.

A mass flowmeter is a flow meter that continuously measures the flow rate of the measured medium, and the measurement results are displayed in engineering units such as kilograms or tons.

Mass flow meters cannot control flow rates. They can only detect the mass flow rate of liquids or gases and output flow values through analog voltage, current, or serial communication. However, a mass flow controller is an instrument that can detect and control at the same time.

A mass flow meter is an instrument used in industrial production for precise medium flow detection with low installation requirements. Due to its ability to directly detect the quality, density, and temperature of the medium flowing through the measuring tube inside the instrument, it does not have strict laminar flow requirements for the flow state of the medium. Therefore, there is no requirement for straight pipe sections in the pipeline before and after the flow meter during installation. Like a regulating valve, it can be installed arbitrarily, greatly facilitating on-site construction and installation.

Why does a quality flow meter not require a straight pipe section? Pipeline flanges, reducing diameters, expanding diameters, rectifiers, elbows, and valves can all have an impact on the fluid; All flow meters based on flow rate have certain requirements for straight pipe sections, in order to make the measurement conditions of the flow meter similar to the laboratory calibration conditions; The mass flow meter has no relationship with the flow rate of the medium, eliminating the need for straight pipe sections.

As long as some details are paid attention to during the installation process, there is almost no need for maintenance after the mass flowmeter is put into operation, and the probability of failure is also very small. As long as the medium is not in a two-phase flow state during the flow process, it can operate stably.

During the first operation of the mass flowmeter, some simple settings are made, such as the form of the output signal, various coefficients of the flowmeter itself, the density of the medium in use, the upper and lower temperature limits, etc. Basically, after being set before use, there is no need to change them.

KOBOLD flowmeter spot model VKG-2105UOR15，Testing and maintenance methods for KOBOLD flowmeter:

Junling Industrial Equipment (Shanghai) Co., Ltd., today let the technical personnel of German Kebao Quality Flow Meter share and explain with us the testing and maintenance methods of KOBOLD flow meters.

1. Regularly observe the malfunction indication of the flowmeter

According to the different models, specifications, and manufacturers of Kebao flow meters, the fault display methods and contents also vary. For different fault alarm indications, you can refer to the product manual to determine the cause of the fault and handle it accordingly.

2. Regular comprehensive inspection and maintenance

For flow meters in use, regular comprehensive inspections should be conducted: starting from the appearance of the sensor, the degree of installation firmness, the vibration of the process pipeline, the indication of the transmitter and display instrument, etc., a comprehensive inspection should be carried out item by item, and any problems found should be dealt with in a timely manner.

3. Establish a file for flow meters

In order to ensure the long-term reliable operation of the flowmeter, users should establish a record of the flowmeter, make detailed records of each inspection, maintenance, and calibration, and include them in the file for better maintenance and use in the future.

4. Maintenance for measuring easily scaling fluids

When measuring fluids that are prone to scaling (such as water and wax) with KOBOLD flow meters, the operating conditions should be checked regularly. When abnormal or significant deviations are found in the flow meter, the possibility of scaling inside the sensor should be considered first. The sensor should be removed and appropriate methods such as blowing or cleaning should be used for treatment.

5. Regular calibration

According to the different application scenarios of the flowmeter, regular calibration should be carried out according to the requirements of the standard system.

KOBOLD quality flowmeter has the characteristics of high precision and strong stability. To maintain these characteristics of the mass flowmeter, it is necessary to regularly inspect and maintain it. Only when the quality flow meter is in good condition can accurate measurements be obtained and the effectiveness of the quality flow meter be maximized.

6. Zero point inspection (zero calibration)

Zero drift is a common problem encountered in the practical operation of Coriolis mass flow meters: there are many factors that cause zero drift, such as installation stress of sensors, asymmetric structure of measuring tubes, and changes in physical properties of the measured fluid. Especially in low flow measurement, zero drift has a serious impact on measurement accuracy. So it is very necessary to conduct regular zero point checks and adjustments.

Zero point inspection should be conducted at least once every three months. If production permits, the time interval for zero point inspection should be appropriately shortened for Coriolis mass flow meters installed at important monitoring points. Whether the zero calibration is completed intact is the key factor that directly affects whether the flowmeter operates within the accuracy range.

7. Inspection of working parameters
