Seametrics PE202 Specifications
PE202
d
C
LOW FLOW MAGMETER
APPLICATIONS
Chemical injection
Corrosive materials
Low ow applications
Pulsating ows
(e.g., metering pump)
Features
• No moving parts
• Requires no straight pipe
• Pulse and/or 4-20 mA output
• Chemical and corrosion
resistant
• Insensitive to uid density and
uid viscosity changes
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. Accuracy is maintained with conductive uids (>20
microSiemens) of varying viscosities and densities.
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
powering analog devices. Outputs and power are provided through a 20
foot (6 meter) cable with 8-pin female circular connector.
