PE202 INSTRUCTIONS

Seametrics • 253.872.0284 Page 3 seametrics.com

The PE202 magmeter is designed for low-ow chemical

injection or difcult-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 PE202 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 (consult factory for chemicals and

concentrations). Accuracy is maintained with conductive

uids (>20 microSiemens) of varying viscosities and

densities.

FEATURES

GENERAL INFORMATION

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 optoisolated current sinking pulse

output that can be connected to the Seametrics FT430/440

rate/total display or FT520 batch processor, as well as an

optoisolated 4-20 mA current loop for analog devices.

Outputs and power are provided through a cable with

8-pin female circular connector.

PE202 INSTRUCTIONS

Seametrics • 253.872.0284 Page 6 seametrics.com

Positioning

The PE202 can be mounted vertically or horizontally. 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

It is highly recommended to use the mounting bracket

provided. The mounting bracket uses two #8 screws on a

1.5” center.

The PE202 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 leakage or

damage to the meter.

FLOW

INSTALLATION

Piping

Metal pipe, metal tube, or plastic tubing can be used with

the meter. The standard NPT ttings can be used with or

without NPT adapters on 3/4” or 3/8” pipe. If used, apply

Teon tape onto the NPT ttings. NPT adapters should be

hand tightened onto the ttings. Thoroughly clean the

pipe threads and nose and apply Teon tape to adapter

threads. Hold adapters with a wrench while tightening the

pipe to prevent damage to the meter.

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.

Grounding

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. The cable

shield drain wire should be left unconnected.

PE202 INSTRUCTIONS

Seametrics • 253.872.0284 Page 7 seametrics.com

Power and signal connections are provided through the

8-pin male bulkhead connector on the meter housing

(20 ft (6 m) cable provided). See the Pin Assignment and

PE202 INSTRUCTIONSOPERATION AND TROUBLESHOOTING

TROUBLESHOOTING

The meter will output one pulse when powered up. The

newly-installed 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.

OPERATION

The 4-20 mA signal outputs 4 mA at zero ow and 20 mA at

20 gallons/minute ow or 3 gallons per minute, depending

on model.

The pulse signal is a 50% duty cycle pulse set at:

PE202-075: 500 pulses/liter (1892 pulses/gallon)

PE202-038: 1,000 pulses/liter (3785 pulses/gallon)

Problem Probable Causes Things to try…

No output Reversed ow direction Reverse ow connections

Empty pipe Check piping conditions

Flow rate below minimum Select a different ow meter

Loose or incorrect wiring Check electrical connections

Fluid conductivity too low Select a different ow meter

Electrical noise Relocate meter or reduce noise

Flow rate incorrect Fluid conductivity too low Select a different ow meter
