1. What are the brands of flow meters in Japan? The best flow meter for a Japanese brand is definitely Yokogawa Tanho, YOKOGAWA。 The worlds first electromagnetic flowmeter was produced by Yokogawa Seize. Yokogawas vortex flowmeter and intelligent pressure transmitter series are also well-known. Yokogawa is called Chongqing Yokogawa Instrument Co., Ltd. (CYS) in China. It was jointly established in 1995 by Yokogawa Electric Corporation of Japan and China Silian Instrument Group Co., Ltd. Another good Japanese brand is Tokyo Design, TokyoKeiso.Ltd。 Mainly producing a series of float flow meters. In China, it is called Shanghai Xindong Instrument and Meter Co., Ltd. Gongsun Closed Finger Company, which was jointly established in 2002 by Hong Kong Xinda Industrial Development Co., Ltd. and Japans Tokyo Design Co., Ltd. Another Japanese brand is Sanbu, YAMATAKE。 The products are also very comprehensive. You really dont know about AKATUKA, it looks a bit like Sanmu. 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 t
2. System key parameter adjustment ① Gain adjustment: Changing the signal amplification factor directly affects the accuracy of flow measurement, and needs to be debugged step by step according to the characteristics of the pipeline medium. ② Integral time: Set the range from 0.1 seconds to 1 minute, take the low value for high-frequency response scenarios, and recommend a steady-state measurement of 0.5 seconds or more. ③ Bias current: used to correct zero drift. It is recommended to perform zeroing calibration in an empty tube state.
3. Software collaborative configuration: ① Data acquisition: Set the acquisition frequency to 3-5 times the flow fluctuation period to ensure complete signal recording. ② Control algorithm: When using PID algorithm, it is recommended to set the initial value of the proportional coefficient to 1% -2% of the range, and then fine tune the integral and derivative parameters. Special attention should be paid during operation: no more than three parameter values should be modified at a time, and the devices operating status should be observed for at least 10 minutes after saving. The flow meter has an internal parameter linkage mechanism. If the medium density parameter is changed, it will automatically affect the temperature compensation coefficient. It is recommended to refer to the Qinghua supporting operating condition manual to adjust the associated parameters synchronously.
