Corrosion-resistant flow meter suitable for Agricultural & Industrial based applications
The SeaMetric's PE202 mag meter has been 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, it can handle fluids containing particulate matter without clogging or jamming, keeping maintenance at a minimum. No metallic parts (100% PVDF body and PVDF carbon fiber-filled electrodes) mean that the PE202 flow meter is corrosion-resistant and compatible with a wide range of chemicals. Accuracy is maintained with conductive fluids (>20 microSiemens) of varying viscosities and densities.
This meter is compact enough to fit most pump/injection systems. With zero straight pipes required after an elbow, it can be easily mounted in tight spaces. The mounting bracket adds stability. The PE202 meter also 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 an 8-pin female circular connector.
Applications: Chemical injection, Corrosive materials, Low flow applications, Pulsating flows (ie: metering pump)
- No moving parts
- Requires no straight line
- Pulse and/or 4-20mA output
- Chemical and corrosion resistant
- Insensitive to fluid density and fluid viscosity changes
