Magnetrol's Polaris is an accurate, repeatable electromagnetic flowmeter that can measure liquids with a conductivity as low as 5 uS/cm in closed pipes, and is suitable for a variety of water and sludge flow applications. Its Polaris transmitter is backlit, rotatable and can measure forward and reverse flow rates as well as total volume. HART capability allows Polaris to use PACTware for configuration and diagnostics.
