CERTIFIED COMPANY
GENERAL INFORMATION, FEATURES and SPECIFICATIONS
The PE102 magmeter is designed for low-ow chemical injection or difcult-to-meter applications with pulsating metering
pumps in 3/4” to 1/4” pipe/tube. The housing is made of sturdy splashproof HDPE plastic.
With no moving parts, the PE102 can handle uids containing particulate matter without clogging or jamming, keeping
maintenance at a minimum. With no metallic parts (100%
PVDF body and PVDF carbon ber-lled electrodes), the meter is corrosion-resistant and compatible with a wide range of
chemicals. Accuracy is maintained with conductive uids (>20
microSiemens) of varying viscosities and densities.
FEATURES
8-pin circular bulkhead connector, 20 foot (6 meter) cable provided
Internals made of chemical and corrosion-resistant PVDF
Sturdy HDPE housing
FlareTek ttings
are standard
Mounting bracket
SPECIFICATIONS*
The PE meter is compact enough to t most pump/injection
systems. With zero straight pipe required after an elbow, it
can be easily mounted in tight spaces. The mounting bracket
adds stability.
The PE meter has an optocoupled current sinking pulse output that can be connected to the Seametrics FT420 rate/total
display or FT520 batch processor, as well as a 4-20 mA loop
for powering analog devices. Outputs and power are provided
through a cable with 8-pin female circular connector.
Threaded NPT adapters
can be purchased separately
(available in polypropylene or
PVDF, PVDF shown)

INSTALLATION and CONNECTIONS
INSTALLATION
Positioning. The PE102 can be mounted vertically or horizon-
tally. It is important to choose a position that will ensure full
pipe. (Under certain conditions of empty or partially-full pipe
the meter may give a pulse out when there is no ow.) With a
zero straight pipe requirement after an elbow, the PE meter
can be installed in tight spaces.
Mounting. The PE102 may be supported by its piping connections IF the piping is rigid. The meter and pipe must be perfectly aligned with no exion at the ttings to prevent damage
to the meter and leakage. It is highly recommended to use the
mounting bracket provided. The mounting bracket uses two #8
screws on a 1.5” center.
Piping. Metal pipe, metal tube, or plastic tubing can be used
with the meter. The standard FlareTek ttings can be used with
or without NPT adapters on 3/4” or 3/8” pipe. If used, NPT
adapters should be hand-tightened onto the ttings to avoid
damage to internal O-ring seals. Thoroughly clean the pipe
threads and nose and apply Teon tape to adapter threads.
Hold ttings/adapters with a wrench while tightening the pipe
to prevent damage to the meter. If using FlareTek ttings, follow the installation instructions provided with your are tool.
Power Supply. A 12 Vdc linear, regulated power supply with an
output current of at least 0.25A is recommended. If a switching
power supply must be used, consult Seametrics for approved
manufacturer’s model numbers.
CONNECTIONS
Power and signal connections are provided through the 8-pin
male bulkhead connector on the meter housing (20ft (6m)
cable provided). See the Pin Assignment and Connections
diagrams below.

Arrangement
In addition, it is necessary for proper operation to ground the
unit to a good quality earth ground. Assure negative power
supply is grounded to earth and to the entire electrical/mechanical system. If metal piping is used, jumper inlet and
outlet pipes together and connect to ground for best results
in metering accuracy.

OPERATION and TROUBLESHOOTING
OPERATION
The meter will output one pulse when powered up. The newlyinstalled meter takes from a few seconds to a minute for the
signal to stabilize at startup, especially if it has been dry. In
normal operation, keep the meter lled with uid and powered on to prevent this delay. When the meter is mounted
properly, an empty pipe detection feature will normally detect
absence of liquid in the pipe and register zero ow.
The 4-20 mA signal outputs 4 mA at zero ow and 20 mA at
TROUBLESHOOTING
20 gallons/minute ow or 3 gallons per minute, depending
on model. The pulse signal is a 50% duty cycle pulse set at
PE102-075: 500 pulses/liter (1892 pulses/gallon),
PE102-038: 1,000 pulses/liter (3785 pulses/gallon).
