1. Can the header of the Yokogawa EJA vortex flowmeter be turned?
The header of the Yokogawa EJA vortex flowmeter can usually be turned, and the operation needs to be standardized. The head design of the Yokogawa EJA series vortex flowmeter has taken into account on-site operational requirements, and its mechanical structure allows for angle adjustment. This design is commonly used to solve human-computer interaction problems when the installation position of the body is limited, such as high-level pipeline installation or narrow side space scenarios. two Optimization of the perspective of the core application scenario: When the flowmeter is vertically installed on a high-level old and dry pipeline, the meter head can be rotated 180 ° to make the display screen face downwards; When installed on the side of a horizontal pipeline, it can rotate horizontally by about 90 ° -120 °, ensuring that the operator can clearly read parameters such as instantaneous flow rate and cumulative value on the regular inspection channel. three Standard operating procedure steps decomposition: ① Deactivate the associated banquet hall control system and execute the safety locking procedure ② Loosen the 4 M8 fixing bolts on the bottom flange of the meter head with an Allen wrench ③ Rotate the meter head clockwise along the axis (maximum allowable torque is 5N · m) ④ After visually verifying the display direction of the LCD screen, tighten the bolts gradually in a cross manner. Note that for some models with Hart communication protocol, rotating the angle beyond 270 ° may cause signal wire entanglement. At this time, it is recommended to disconnect the wiring terminals first. four The special model difference is that the EJA110A mecha
2. Parameter Setting Method for Henghe Flow Meter
The core operation process for setting parameters for Henghe Flow Meter consists of three levels: basic parameter setting, system optimization adjustment, and software collaborative configuration.
. 1. Basic parameter setting process ① Enter setting mode: Press and hold the "SET" button and turn on or reset until the screen displays "SETUP". ② Select parameter item: Use the left and right arrow keys to select the target parameter, press the "ENT" key to confirm and view the current value. ③ Numerical modification: Use the left and right arrows to adjust the numerical value. When the new value takes effect, the device will emit a brief prompt sound. ④ Save parameters: Press the "SET" button to trigger the save, and the screen will display "SAVE" with a long tone indicating successful storage. ⑤ Exit operation: Wait for 5 secon
