TFW,TFM-200

Since I am trying to use the sensor near its lower limit, the display is not very stable, so is there a way to stabilize it?

You can stabilize it, for example, by increasing the value of the “Display refresh time (setting No.16)” or the value of the “Moving average of the instantaneous flow display (setting No.17).”

But in this case, the display response time is slower, so please take care.

What should I do to display the instantaneous flow rate in US gallons per hour?

Set “Display refresh time (setting No.13)” to “2.L”, and “Unit selection (setting No.25)” to “1.P/mL.” Further, from the fact that 1US gallon = 3.785L, in “Pulse rate (setting No.24)”, please set the K factor as the value normally set x the value of 3.785.
