TFM VT-222 Vortex Flowmeter User Manual
Pipe diameter
The pipe size is selected from a range of sizes.
The flow meter size can be set through RS485 communication or keys, the setting range is 2-2000, and the unit is
fixed in mm.
The diameter is manually input, and the flow lower limit, flow upper limit, and maximum magnification must be
manually input.temperature unit
The temperature unit is increased by
℉
(Fahrenheit), that is, the temperature unit can be switched between Celsius
and Fahrenheit.
Pressure Unit
The pressure unit is increased by PSI, that is, the pressure unit can be switched between KPa or PSI.
Standard pressure point and standard temperature point
The standard state of H880TBR corresponds to a fixed 20°C and 101.325KPa.
Now H86CT1 supports users to set standard pressure value and standard temperature value, that is, pressure point
and temperature point in standard volume state. For example, it can be set to 68 degrees Fahrenheit, 101325 Pa or 32
degrees Fahrenheit 100KPa, and the corresponding state is used as the standard state. When the set unit is the
standard condition unit, the condition flow rate will be converted to the standard condition flow rate of the set point.
Flow correction factor
Global flow correction factor, the setting range is 0.1-10. For example, if it is set to 1.1, the flow will be increased
by 10%.
Test modes
Use the 3 button interface to enter the Code screen, and enter the password 02086 to enter the test menu. Users can
choose any function: flow test, frequency test or current test.
Note: In the test mode, the cumulative flow does not participate in the accumulation.
The specific test functions and operation instructions are as follows:
Traffic test mode
1. After selecting the flow test menu, the interface prompts "flow test", the unit is the current instantaneous
flow unit, and the second line prompts the current flow (it may also be initially 0, depending on the
programming). It doesn't really go into test mode at this point.
2. After inputting the new flow rate and saving it, it enters the test mode. At this time, the meter calculates
the percentage, outputs the current value, output pulse value, etc. according to the input instantaneous
flow rate value, and outputs it accordingly. The backlight flashes to alert the operator that it is in the test
mode at this time. If there is no new key operation within 10 minutes, it will automatically exit.
