SVF128 digital vortex flowmeter provides a local display and setting, can display several variables on the local multi-functional LCD display. The converter also has 3 buttons so clients can do settings on it.
4.1 Instruction of multi-functional LCD display
SVF128 digital vortex flowmeter has a display to indicate “Frequency” “Flow rate” “Total flow”. The SVF128 multi-variable version or a standard SVF128 working with RTD and pressure transmitter can also indicate other variables such as “Temperature” “Pressure” “Density” “Mass flow” etc. Please refer to picture 3.1 below.
Picture 4.1: LCD display
The LCD display has 2 areas to display the content, the upper row, the lower row. The upper row displays the flow rate/mass flow/standard flow rate. Below the upper row shows the unit of the variable displayed in the upper row.
The lower row display indicates other variables, such as frequency/ pressure/ temperature/ density/total flow/ velocity. And below the lower row shows the unit of the variable displayed in the lower row.
Please refer to picture 4.2 for display
Picture 4.2: Flow rate and total flow
SVF128 multi-variable version or a normal version with temperature and pressure compensation can calculate and display the mass flow of steam, both saturated steam and superheated steam. Please refer to picture 1.3 for mass flow rate displaying.
Picture 4.3: Mass flow and total flow of steam displaying
SVF128 multi-variable version or a normal version with temperature and pressure compensation can display variables such as temperature/ pressure/ density. Use the switch button to switch to the next variable and it will display for 30 seconds.
Please refer to picture 4.4 as a sample of temperature displaying. You can also keep the lower row consistently display a variable by setting. The default variable displayed in the lower row is total flow.

You can also set the lower row to display several variables in a circular turn.
4.2 Unit of the variable displayed
The variables that can be displayed in the lower row and their units that can be displayed are as the chart 4.1 below.
|Subject||Variable||Unit||Circular display code|
|TOTAL||Total flow||Nm3, m3, L, kg or t||01|
MPa or kPa
Chart 4.1: The displayed units
SVF128 series digital vortex flowmeter has three buttons on the top of the displayer, which are:
|[↔]||will be mentioned as “L-R button” below|
|[↕]||will be mentioned as “U-D button” below|
|[↲]||will be mentioned as “Enter button” below)|
Please refer to below picture
When underworking, use “U-D button” to switch the displaying content, use “L-R button” can switch to the left and right digits of total flow. “Enter button” is to display the entire digits of total flow directly.
When the flowmeter is under the setting mold, the “L-R button” means move to left and right to select the digit, the “U-D button” means to set the digit to a number, the “Enter button” means “confirm”. All the “Digital setting” and “Code setting” of the SVF128 vortex flowmeter are made through these 3 buttons.
Please refer to the related article for details.
4.3 Total flow displaying
SVF128 can display 9 digits left to the decimal point and 3 digits right to it. When there are more than six digits, the total flow reading will be displayed two times. One time displays the right digits and the other displays the left digits. You can use the “L-R button” to switch between the right digits and left digits. The left digits will be displayed with a mark of “x1000”.
Please refer to picture 4.6
Picture 4.6: Displaying the left digits, a “x1000” mark is displayed
If you want to check the right digits now, please pressure the “L-R button”, the display will be as in picture 4.7 below.
Picture 4.7: Displaying the right digits
According to pictures 4.6 and 4.7, the total flow is 569864.581 kg.
SVF128 series vortex flowmeter has three different statuses as below
- Working status
- Setting status
- Calibration status
When under working status, please follow the instruction in 7.1 to switch the parameter displayed.
When under setting status, you can set the flowmeter, while the flowmeter is still processing, so the setting will not have an effect on the measuring. In the next chapter, there will be instructions on how to do the set.
The calibration of the flowmeter has been finished in the manufacture’s lab before delivery, including temperature and pressure calibration and the setting of high-limit and low-limit of 4~20mA simulation output. Thus, customers don't need to do anything.
