What is the Strouhal number of the Yokogawa vortex flowmeter?
Sr is the Strouhal number, which is mainly related to the Reynolds number. When the Reynolds number is between 300 and 3 × 10 ^ 5, the Sr near equilibrium value is similar to a constant value (0.21); When the Reynolds number is between 3 × 10 ^ 5 and 3 × 10 ^ 6, the regular vortex street no longer exists; When the Reynolds number is greater than 3 × 10 ^ 6, the Karman vortex street will automatically appear again, and Sr is about 0.27 at this time. The Strouhal number is not a parameter of a flowmeter, but a characteristic of flow. The Technical Department of Yunnan Xibote Technology Co., Ltd. instructs Yuanpi on how to adjust the accumulated value of the Henghe Vortex Flow Meter DY050 to a decimal place. Currently, there is no specific operation method for adjusting the accumulated value of the Henghe Vortex Flow Meter DY050 to a decimal place in the public information. 1. The product description of the core solution is the most direct basis, usually with detailed operation procedures in the "Parameter Settings" or "Cumulative Unit Adjustment" chapters. Most models of Yokogawa Instruments support entering the parameter correction interface through the combination buttons or password mode on the device panel. If the manual is missing or the operation is cumbersome, it is recommended to prioritize submitting the device model and problem description through the online technical support portal on Yokogawas official website, or calling the after-sales service hotline. Some parameter adjustments involving hardware firmware require professional equipment matching
3. Precautions for operation: Before adjusting parameters, it is recommended to record
3. Several connection methods for the output status of Yokogawa DY vortex flowmeter!
Several connection methods for output status of Yokogawa DY vortex flowmeter mainly include the following three methods:. A DC power supply is required in the transmission circuit, and the total wire resistance including the instrument load and power distributor (to be provided by the user) must comply with the allowable range of load resistance. Attention: The relationship between power supply voltage and load resistance should be configured according to relevant technical documents to ensure the stability and accuracy of the output signal. The resistance and capacitance parameters of transmission lines may also affect the output signal, so necessary testing and calibration are required in practical applications.
2. Connection method for pulse output and alarm/status output: Three wire transmission method is adopted, requiring a DC power supply and load resistor.
. Pulse output is usually connected to an integrator or electronic counter for recording or displaying flow data. Alarm/status output is used to indicate the working status or fault condition of the flowmeter. Features: The low level of pulse output is 0-2V, suitable for connection with devices such as integrators or electronic counters. Communication on the transmission line is not possible. Communication is carried out through an amplifier board and is not r
