• Note: Every SVF128 digital vortex flowmeters has been set according to requirement before delivery, please do not change setting unless it is necessary and under correct instruction!

SVF128 series digital vortex flowmeter have digital setting and code setting. Use code setting to set parameters such as fluid type, compensation type and output signal. Use digital setting to set parameters related to a number, such as pipe size, flow range, factor.

5.1 How to set

5.1.1 Code setting

Under working status, to enter code setting, please hold “Enter button” then press “U-D button” at the same time. Please reference to picture 5.1.

Picture 5.1: Enter and quit code setting

When in code setting, the first row will display the reference number of the code setting, and the lower row will display the contents of this parameter. The digit that is flashing is the digit under the setting. Please reference to picture 5.2, which means C01=02, means fluid type is liquid.

Picture 5.2 Code setting

When under code setting, Now, the user can use “L-R button” to choose which digit on the displayer are to be set and use “R-D button” to switch the digit to 0~9 . The first time of pressing “Enter button” means to set the lower row. Press the “Enter button” again to check if the setting is available. If setting is available, the setting mode will be canceled and the display will not flash, then press “L-R button” or “U-D button” to set it again. When display is not flashing, pressure “Enter button” to save and go to next setting.

If want to quit the code set, same as entering, please hold the “Enter button” then press “U-D button” at the same time.

5.1.2 Digital setting

Under working status, to enter code setting, please hold “Enter button” then press “L-R button” at the
same time. Please reference to picture 5.3.

Picture 5.3: Enter or quit digital setting

When in digital setting, the first row will display the reference number of the digital setting, and the lower row will display the contents of this parameter. The digit that is flashing is the digit under setting. Please reference to picture 5.4, which means D001=1.60000, max pressure is 1.6 (unit according to other setting.)

Picture 5.4: Digital setting

When under digital setting, Now, user can use “L-R button” to choose which digit on the displayer are to be set , and use “R-D button” to switch the digit to 0~9 . The first time of pressing “Enter button” means to set the lower row. Press “Enter button” again to check if the setting is available. If setting is available, the setting made will be canceled and the display will not flash, then press “L-R button” or “U-D button” to set again. When display is not flashing, pressure “Enter button” to save and go to next setting.

If want to quit code setting, same as entering, please hold “Enter button” then press “U-D button” at the same time.

5.2 Setting list

Please check chart 5.1 and 5.2 for code and digital setting address list.

Chart 5.1: Code setting address

• Note:
  If the unit of flow rate is changed or measurement changed from flow rate to mass flow, users can reset the total flow to 0 or record the current total flow.
  Total flow=(time of over total flow)* (max display of total flow)+(current total flow reading)

Chart 5.2: Digits setting address

Note: Max freq output=10KHz, the pulse factor for total flow should be set properly set according to the current total flow.

5.3 Example of setting

Sample: For vortex flowmeter SVF128, measure gas in DN50 pipe, K factor= 7.802P/L, density preset, mass flow display unit is kg/h. 4~20mA output with a flow range of 0~4000kg/hr

5.4 Password setting instruction

There is no password set in default in a new SVF128 digital vortex flowmeter ,users can set a password following instruction below.

Enter code setting, set C47=01, confirm and quit then enter the password setting interface as picture 5.5

Picture 5.5: Password setting interface

To set a new password, users have to input the correct password twice, the password will become effective only if the both inputs are the same; or users have to input again. If the power is off during a password setting process, the password will be 2000 as default. When a password becomes effective, users have to input the correct password before he can set the flowmeter, please reference to picture 5.6.

If users input incorrect password 3 times consistently, the display will come back to normal display
