10 Getting Started
Displaying Live Data
Main Display
The main display has these primary functions:
• Displaying live temperature, pressure, and flow data
• Accessing the main menu (MENU) or the optional totalizer (NEXT) (page 11)
• Taring the flow measurement (page 10)
This screen displays live data for all flow parameters simultaneously. Live data is measured
1000 times per second and the LCD display is updated 10 times per second. The button
next to the measurements highlight their values in the center.
Taring Your Flow Meter
MENU → TARE FLOW or TARES
Taring ensures your flow meter provides its most accurate measurements. This function
gives the flow meter a zero reference for flow measurements. For meters with a barometer,
the absolute pressure reading can also be tared when the device is exposed to the local
barometric pressure.
How to Tare
Taring Flow
MENU → TARES → TARE FLOW
Flow tares should take place at the expected process pressure, with no flow. A message,
"ENSURE NO FLOW BEFORE PRESSING TARE" will be displayed. Press TARE to complete the
taring process.
Optional: Taring Pressure
MENU → TARES → TARE PRESS
Absolute pressure tares require an optional barometer, and the meter open to atmosphere.
A message, "PRESS TARE WHEN VENTED TO AMBIENT WITH NO FLOW". The oset between the
absolute pressure sensor in the flow body and the internal barometer will also be displayed.
When to Tare
• Before every new flow measurement cycle
• After significant changes in temperature or pressure
• After dropping or bumping the flow meter
• After changing the device’s orientation
Tare mass flow by selecting
TARES from the main menu.
