Totalizer
A feature of the flowmeter that accumulates the total
volume of fluid that flows past the transducers. The
flowmeter has a positive totalizer, a negative totalizer,
and a net totalizer.
The positive totalizer accumulates the total volumetric
flow in the positive (upstream) direction.
The negative totalizer accumulates the total volumetric
flow in the negative (downstream) direction.
The net totalizer accumulates the total volumetric flow in
the positive direction minus the total volumetric flow in
the negative direction. (For example, if there are 3000
gallons of flow in the positive direction and 1000 gallons
of flow in the negative direction, the net totalizer
indicates 2000 gallons of net flow.)
Totalizer multiplier
The number by which the flow total is to be multiplied
for display purposes. The multiplier is a multiple of 10
which is selected by the user in Menu 37.
Transducer mounting
The mounting method to be used for installing the
transducer (Section 4.4). Refer to V method, Z method,
and W method.
Transducer spacing
The distance between the inside edges of the transducers
(the edges opposite the transducer cable connection.)
Transit time
In flow measurement, the time period for a sound wave to
travel from one transducer to the other.
V method
Installation method in which the transducers are mounted
on the same side of the pipe and the ultrasonic signal
makes two transits of the pipe per pass (Section 4.4.1).
Velocity profile
Refer to Flow profile.
W method
Transducer installation method used on small metallic
pipes. In the W method, the transducers are mounted on
the same side of the pipe and the ultrasonic signal makes
four transits of the pipe per pass (Section 4.4.2).
Z method
Installation method in which the transducers are mounted
on opposite sides of the pipe and the ultrasonic signal
makes one transit per pass (Section 4.4.3).
Zero flow set calibration
A zero set calibration method that is used only when the
flow in the pipe can be stopped (Section 5.1.2). It
automatically applies a zero point. Refer to Zero point
and Zero set calibration.
