Universal Flow Monitors (UFM) Vortex Operating Manual

Install in pipe making sure to orient IN port to flow supply.

10 pipe diameters distance is required upstream and 5 down for best accuracy.

Use proportional spacing if this much space is not available.

50 pipe diameters are required upstream as distance from a valve.

No use of Teflon tape please. (See detailed piping instructions.)

Attach cable assembly using grease (included) for added sealing around pins.

Setup

At startup, digital display of 8.8.8 to show that all segments are present 8.8.8.
Display shows that it is a totalizing unit. Tot
Firmware version displayed. 4.66
Gallons/liters are the engineering units. G-L
Total is shown at zero (unless the total was saved). 00.0

Resetting total

Push “Set” button to reset the total to zero. 00.0

Changing from Gallons to Liters

There are two buttons. “Menu” and “Set”.
Menu changes the readings from Gallons to liters and back again.

If set to liters, there is an added decimal at the end 32.3.
If set for gallons, no added decimal point. 8.53
