Description

Seametrics PE202 Low Flow Magmeter

Seametrics PE202 Low Flow 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. Accuracy is maintained with conductive fluids (>20 micro siemens) of varying viscosities and densities. The PE 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.

Core Operational Principles

Faraday’s Law Electromagnetic Sensing: Creates a magnetic field across the sensor flow channel. As conductive liquid ( $\ge 20\text{ }\mu\text{S/cm}$ ) flows through, a voltage is generated across the Hastelloy electrodes proportional to liquid velocity.
Full-Bore Plastic Construction: Features a PVDF (Kynar®) or polypropylene body with no internal obstructions or moving rotors, preventing fouling from suspended solids or crystallization.
Low-Flow Optimization: Designed specifically for small tube diameters ( $1/2\text{''}$ to $3/4\text{''}$ ) where low flow rates render standard insertion or flanged magmeters ineffective.
