GENERAL INFORMATION
PE202 INSTRUCTIONS
The PE202 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 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
8-pin circular bulkhead connector, 20 foot (6 meter) cable provided
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.
Mounting bracket
Internals made of chemical and corrosion-resistant PVDF
Sturdy HDPE housing
½” male NPT
ttings standard
Threaded male or female NPT adapters
can be purchased separately
(available in PVDF and PP)
(Female NPT available in 1/2” only)
