Product classification assembly workshop

The JYLDE series intelligent electromagnetic flowmeter consists of a sensor and an intelligent signal converter. According to the assembly form of the converter and sensor, it can be divided into two structures: integrated and split.
Integrated: The converter and sensor are directly assembled as a whole and cannot be separated. Commonly used in sites with good environmental conditions.
Split type: The converter is composed of a dedicated cable and a sensor to form a product, with the sensor installed on site and the converter installed in a location with better conditions. Commonly used in sites with poor environmental conditions, such as underground wells, high temperatures, and places that are difficult for personnel to reach.

Six Selection Guidelines for Testing and Calibration Workshop
1 caliber selection
The diameter of the flowmeter should be the same as that of the process pipeline. If in the following two situations:
① The flow rate inside the pipeline is too low to meet the flow meter's requirements for the flow rate range or to achieve high measurement accuracy at this flow rate.
② The medium is prone to adhere to the pipe wall, which affects the normal use of the flowmeter.
You can choose a flow meter with a diameter smaller than the process pipeline, but you need to do a good job of reducing the diameter.

Only one cable is needed to connect the converter and sensor, and the specific length should be confirmed with the manufacturer when ordering. Otherwise, only 5 meters will be provided at the factory.
For other situations, an integrated flowmeter can be used.
When unsure, consult the manufacturer.
8 Determination of output signal
The flowmeter can choose to output 4~20mADC or 0~1kHz or RS485 separately, or choose various combinations of three signals at the same time. In addition, when selecting 4-20mA output, HART communication can also be optionally selected.

Selection of anti-corrosion intelligent electromagnetic flowmeter
◆ Range confirmation
For general industrial explosion-proof flow meters, it is advisable to measure a medium flow rate of 2-4m/s. In special cases, the lower flow rate should not be less than 0.2m/s
It should not exceed 8m/s. If the medium contains solid particles, the commonly used flow rate should be less than 3m/s to prevent excessive friction between the lining and the electrode; For viscous fluids,
The flow velocity can be chosen to be greater than 2m/s. A higher flow velocity helps to automatically eliminate the effect of viscous substances attached to the electrode, which is beneficial for improving measurement accuracy.
Under the condition that the range Q has been determined, the size of the flowmeter diameter D can be determined based on the range of flow velocity V mentioned above, and its value can be calculated by the following formula:
Q=π*3600D²V/4
Q: Flow rate (m ³/h) D: Inner diameter of pipeline V: Flow velocity (m/s)
The range Q of the explosion-proof intelligent electromagnetic flowmeter should be greater than the expected maximum flow value, while the normal flow value should be slightly greater than 50% of the flowmeter's full range scale.
