The 

PE202

  magmeter  is  designed  for  low-flow  chemical 

injection  or  difficult-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  fluids 

containing particulate matter without clogging or jamming, 

keeping maintenance at a minimum. With no metallic parts 

(100% PVDF body and PVDF carbon fiber-filled 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 

fluids  (>20  microSiemens)  of  varying  viscosities  and 

densities.

FEATURES

GENERAL INFORMATION

The PE meter is compact enough to fit 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

Sturdy HDPE housing

8-pin circular bulkhead connector, 20 foot (6 meter) cable provided

½” male NPT

fittings standard

Internals made of chemical and corrosion-resistant PVDF

Threaded male or female NPT adapters

can be purchased separately

(available in PVDF and PP)

(Female NPT available in 1/2” only)
