PE02 Low Flow Electromagnetic flow meters

Low Flow Electromagnetic Flow Meters

The PE102 seametrics 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 PE102 flow meter 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 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.

FEATURES

• No moving parts
• Requires no straight pipe
• Pulse and/or 4-20 mA output
• Chemical and corrosion resistant
• Insensitive to fluid density and fluid viscosity changes

APPLICATIONS

•  Chemical injection
• Corrosive materials
• Low flow applications
• Pulsating flows (e.g., metering pump)

The PE flow 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 flow meter has optocoupled current sinking or current sourcing pulse output that can be connected to the Seametrics FT420 rate/total display or FT520 batch processor, as well as a 4-20 mA loop for powering analog devices. Outputs and power are provided through a cable with 8-pin female circular connector.
