1. What does total mean in Chinese?
A new design method for flow total is introduced. A design method for a new type of flow accumulator is introduced.
2. Flow meter unit setting
The core method of flow meter unit setting is to clarify the type and gradually adjust the parameters according to the instructions. The universal optional units cover both volume and mass flow rates.
. 1. General optional unit classification Flow display units can be divided into two categories: Volume flow units: L/s, L/min, L/h, m ³/s, m ³/min, m ³/h Mass flow units: kg/s, kg/m, kg/h, t/s, t/m, t/h2. Tiankang electromagnetic flowmeter unit setting: ① Long press the composite key+confirm key to enter the password (usually 0000 initially) ② Enter the parameter settings and select the "Flow Units" or "PV Units" menu ③ Switch the target unit through the up and down keys and confirm and save ④ After parameter verification, long press the confirm key to return to the measurement state 3 Operation scheme one for electromagnetic flowmeter MAG6000: Modify unit parameters directly through the Basic setting → Totalizer menu. You can refer to the video tutorial to locate the operation node. Scheme two: Use the selection key to move the cursor to the unit position on the accumulator menu interface, and cycle through the change key to switch options U53 Ultrasonic Open Channel Flow Meter Configuration Steps: ① Select "CONFIGURE → FLOW FORM" from the main menu, ② Execute "SET FLOW UNITS" to set the basic unit, ③ Adjust the range multiple and determine the decimal point accuracy through "SET MULTIPIER", ④ Confirm step by step and return to the measurement interface to take effect.3. Siemens Boruto calculates cumulative fl
In Siemens Boruto, instantaneous flow rate can be calculated using three methods: function block, structured programming, or timed reading and calculation.
. 1. Use the function block "Totalizer" in the STEP7 V5. x environment. The function block "Totalizer" is a tool specifically designed for traffic accumulation calculation. Its core parameters include: measured value: input instantaneous flow rate value (such as cubic meters per second, liters per minute, etc.); Interval Time: Set the calculation cycle (such as 1 second, 1 minute) to match the actual physical unit; Cycle Time: The scanning cycle of the PLC must be synchronized with the calculation logic; Reset signal: When triggered, reset the cumulative value to zero. By combining the instantaneous flow value with the time parameter, the function block automatically completes the integration operation internally and outputs the cumulative flow result. This method is suitable for scenarios with moderate accuracy requirements and simple logic, but attention should be paid to the compatibility differences between STEP7 V5. x and TIA Botu. In TIA Botu, structured programming can be implemented by creating new functional blocks (such as "FB39_LowAccumulate") to achieve more flexible accumulation calculations. The specific logic is as follows: Loop interrupt organization block call: It is executed periodically in loop interrupt blocks such as OB35 (e.g. every 100ms); Trapezoidal integration formula: When the instantaneous flow rate (# FlowInOut) is within the set range, the cumulative value (# FlowAccSta) is updated according to the formula: # FlowAccSta:=# FlowAccSta+0.5 * # ScanTime * (# FlowInOut+# LastFlow), where # Sc
