PanaFlow™ Z1G Quick-Start Guide
1. Thank you. Thank you for purchasing the
PanaFlow Z1G Ultrasonic Flowmeter. If you have any
questiosn, see Step 8 for our contact information and
page 4 for our Customer Support Centers locations.
Before removing the PanaFlow Z1G system from the
shipping crate, inspect the flowmeter carefully. Each
instrument manufactured by GE Measurement &
Control is warranted to be free from defects in material
and workmanship. Before discarding any of the
packing materials, account for all components and
documentation listed on the packing slip.
2. Meter Installation. The ideal site is a straight
section of process pipe meeting the following criteria:
• The pipe section is horizontal and above ground.
• The pipe section can accommodate the overall
length of the flowcell.
• The flowcell can be installed with the Z1G flow
transmitter located on the top of the pipe.
• There are at least 20 pipe diameters upstream of
the Z1G and 10 pipe diameters downstream of the
Z1G with straight, undisturbed flow.
• There is sufficient clearance around the pipe to
permit easy access for operation and
maintenance of the Z1G flow transmitter.
3. Temperature and Pressure Transmitters. If used,
temperature and pressure transmitters should be
installed in the process pipe at least 2 pipe diameters,
but no more than 20 pipe diameters, downstream
from the Z1G flow transmitter. The temperature sensor
should protrude 1/4 to 1/2 way into the process pipe.
Resistive Thermal Devices (RTDs) are typically a good
choice for the temperature sensor.
The transmitters should output a 0/4-20 mA signal,
and the Z1G must have a suitable option card to
process the signals and to provide the required 24 VDC
power to the transmitters. The transmitters must have
an accuracy of ±0.5% of the reading or better.
4. Power and Option Card Wiring. Remove the Z1G
rear cover. Follow the label inside the rear cover to
connect your option cards at terminal block J2. Wire
the built-in Z1G analog outputs at J1, as shown below.
Connect the Z1G power input terminals to a power
source matching the specifications for your meter.
Then, reinstall the rear cover and o-ring.

5. Communications Wiring. The standard built-in
Z1G serial port is an RS232 port. If desired, this port
may be factory-configured as an RS485 port instead.
Wire the built-in serial port at J1, as shown below.
If the built-in serial port is an RS232 port, a Modbus
option card may be used to provide an additional
serial port for RS485 operation. Wire this port for
Modbus communications at J5, as shown below.
The Z1G can be fitted with a data logging option card
in Slot 2. This option card, which requires no external
wiring, increases the Z1G memory by up to 2 MB.
6. Programming Methods. The Z1G may be
programmed either locally with the magnetic keypad
or remotely via an RS232 serial port link to a PC that is
running GE’s PanaView™ software.
The magnetic keypad permits programming of the Z1G
through its glass faceplate without removing the cover.
Thus, all programming may be performed while the
unit is installed and operating in a hazardous area. Use
the [ENTER] and [ESCAPE] keys along with the four
[ARROW] keys on the magnetic keypad to program the
Z1G flowmeter with its magnetic wand.
7. Initial Setup. Before the Z1G can begin taking
measurements and displaying valid data, the site data
(i.e., the system and pipe parameters) must be
progammed into the meter. For a 2-Channel meter,
both channels must be activated prior to use.
Upon power up, the Z1G displays the model name and
the software version:
The meter then starts to display flow measurements.
To enter the Keypad Program, press the [Escape] key,
[Enter] key, and [Escape] key again, with no more than
10 seconds between key presses. Refer to the Menu
Map on the next page, and use the magnetic wand and
keypad to program the CH1/CH2 and GLOBL data into
the Z1G.
