TTFM 6.1 Transit Time Flow Meter
SET UP (cont.)
Vel
When Lining = Other, enter speed of sound of liner (consult
factory).
Thick
When Lining ≠ None, enter liner thickness.
Crossings
Crossings 1 = Z mounting
Crossings 2 = V mounting
Crossings 4 = W mounting
Nominal Pipe Size, Inches
Recommended Crossings
2-24
Crossings = 2
> 24
Crossings = 1
Older pipes are often degraded or scaled on the inside. These
conditions can hinder the ability to receive a strong signal
when Crossings = 2. Greyline suggests starting with Crossings
= 1 in cases such as these.
Zero Tare
Used to calibrate zero-flow measured by the TTFM 6.1 in
process. Flow in the pipe should be confirmed as 0 before
enabling, or significant errors in flow accuracy could occur.
Set Calibration/Damping to 0%, and under no flow conditions
and with a full pipe, select Yes to force readings to zero.
Sens Space
After sensor, angle, fluid, and pipe material are defined, this
displays the calculated sensor spacing. Also called the
separation distance. The sensors will be set to this dimension
when installed on the pipe, as described later in this manual.
Velocity
Displays the measured velocity after the sensors have been
connected at the specified separation distance.
