Reliable flow measurement that is
easy on your budget

The PanaFlow Z3 is a three-path, wetted ultrasonic flow
meter that brings together all of the advantages of
ultrasonic technology at a very affordable value. Unlike
other flow measurement technologies, the PanaFlow Z3
does not require maintenance since it does not have
any obstruction in the flow path that could clog the
process line or moving parts to be damaged by the
flowing fluid.

Also, due to the inherent nature of our ultrasonic flow
measurement, the PanaFlow Z3’s measurement is not
affected by changing process conditions (temperature,
pressure, and conductivity) and does not drift over
time, which eliminates the requirement for periodic
calibration. Without requirements for maintenance and
calibration, the PanaFlow Z3 offers high performance
with a low cost of ownership.

What is the PanaFlow Z3?

The PanaFlow Z3 consists of the Panametrics PanaFlow
XMT1000 electronics, three pairs of LX transducers, and
sensor body. The XMT1000 is our latest ultrasonic flow
transmitter with state-of-the-art flow measurement
capability in a rugged enclosure certified for use in
hazardous areas. The LX transducer system is our latest
advancement in ultrasonic transducer technology and
provides accurate, drift-free and obstructionless flow
measurement.

Fast and Easy Installation

Installation of wetted systems can be difficult and if
they are not installed with precision and with close
attention to detail, the reliability and accuracy of the
system may not meet specifications. With the new
PanaFlow Z3 system, the assembly work is done at
the factory. The necessary components are already
installed, so all the user needs to do is to bolt the end
flanges into place.

Transit Time Flow Measurement

In this method, two transducers serve as both ultrasonic
signal generators and receivers. They are in acoustic
communication with each other, meaning the second
transducer can receive ultrasonic signals transmitted
by the first transducer and vice versa.

In operation, each transducer functions as a
transmitter, generating a certain number of acoustic
pulses, and then as a receiver for an identical number
of pulses. The time interval between transmission and
reception of the ultrasonic signals is measured in both
directions. When the liquid in the pipe is not flowing,
the transit time downstream equals the transit time
upstream. When the liquid is flowing, the transit time
downstream is less than the transit time upstream.

LX Transducer

The LX transducer system consists of our new
integrated LX transducers and our uniquely engineered
buffers. The design of this system allows for the safe
insertion and removal of the LX transducers at any time
without isolating the flow meter, shutting down the
process or using any special tools. Together with the
XMT1000 electronics and LX transducer, the uniquely
designed meter body provides a clean and compact
flow meter system.

The difference between the downstream and upstream
transit times is proportional to the velocity of the flowing
liquid, and its sign indicates the direction of flow.

Fluid Types

Liquids: acoustically conductive fluids, including most
clean liquids, and many liquids with small amounts of
entrained solids or gas bubbles.

Correlation transit time model

Accuracy

3 to 24 in (80 to 600 mm)

• ±0.25% of reading for velocities above 1.6 ft/s (0.5
m/s)

• ±1.25 mm/s for velocities below 1.6 ft/s (0.5 m/s)

2 in (50 mm)

• ±0.5% of reading for velocities above 1.6 ft/s (0.5
m/s)

• ±2.5 mm/s for velocities below 1.6 ft/s (0.5 m/s)

Accuracy statement assumes measurement of a
single phase homogenous liquid with a fully developed
symmetrical flow profile passing through the meter
(typically 10 diameters upstream and 5 diameters
downstream of straight pipe run).
Applications with piping arrangements that create an
asymmetrical flow profile may require extended piping
straight runs and/or flow conditioning for the meter to
perform to this specification.

Calibration

All meters are water calibrated at ambient conditions
and include a calibration certificate.

• 3 points as found 2, 5, and 10 ft/s (0.6, 1.5 and 3 m/s)
and 2 points as left 3 and 7 ft/s (0.9 and 2.1 m/s)

Repeatability

• ±0.15% of reading 3 to 24 in (80 to 600 mm)

• ±0.2% of reading 2 in (50 mm)
