1. Flow rate selection: for general industrial use
Anti corrosion flowmeterThe appropriate flow velocity for the measured medium is 2-4m/s. In special circumstances, the low flow velocity should not be less than 0.2m/s, while the maximum flow velocity should be controlled within a range of no more than 8m/s. For media containing solid particles, the commonly used flow rate should be less than 3m/s to prevent excessive wear of the lining and electrodes. For viscous fluids, a larger flow velocity, approximately greater than 2m/s, can be chosen to help automatically remove viscous substances attached to the electrode, thereby improving measurement accuracy.
2. Range and caliber calculation: After determining the appropriate flow rate range, the range can be calculated based on the selection of the flowmeter caliber. The size of the flowmeter diameter can be calculated using the following formula: [Q=π D ² V/4], where Q represents the flow rate (m ³/h), D represents the inner diameter of the pipeline, and V represents the flow velocity (m/h). The range Q should be greater than the expected maximum flow value, and the normal flow value is preferably slightly greater than 50% of the full scale of the flow meter.
3. Range confirmation: The range confirmation of anti-corrosion flow meters is a key step in ensuring accurate and stable operation of the instrument. By selecting the appropriate medium flow rate and calculating the diameter of the flow meter, the accuracy and reliability of the measurement can be improved.
4. Practical application considerations: In practical applications, operators should carefully select appropriate parameters based on the specific characteristics of the medium and process requirements to ensure that the anti-corrosion electromagnetic flowmeter performs the best in industrial production.
Confirming the range of anti-corrosion flow meters is a complex process involving flow rate selection, range and caliber calculation, and practical application considerations. Confirming the correct range not only ensures measurement accuracy, but also extends the service life of the instrument, especially when dealing with corrosive media.
