DemiMag DM Overview

The DM series DemiMags are sized from 1/16” - 1/2” (1.5 - 12 mm), all with 1/2” connectors. The DemiMag features listed below are unmatched by other magmeters. Yearly maintenance / repair costs associated with metering pumps and positive displacement meters can be lowered as a result of this exceptional performance. DemiMags can meter expensive raw materials or additives with greater efficiency, thus improving product quality.

DemiMag DM Feature	Benefit
Patented Pulsed Hybrid coil excitation (High coil current & high pulsation frequency)	Produces a signal-to-noise ratio up to 3x higher than conventional AC magmeters and up to 50x higher than typical pulsed DC magmeters; fast response time achieves stable proportional control, even when measuring media that create high media noise.
Fast time constant of 0.030 seconds	Suitable for high speed batching applications and measuring pulsating flow created by diaphragm or piston style pumps.
Compatible with fluid conductivity > 0.08 microS/cm	Standard design cost effectively measures fluids like alcohol, glycol, distilled water and cutting oil.
Low flow range capability, down to 0 - 0.01 gpm (0 - 2 lph) Resolution to 0.02 fps (0.006 m/s)	Measures flows below 1.5 fps (0.45 mps) with higher accuracy than other magmeters; prevents overdosing and underfeeding; suitable for paper additives, pilot plant and research applications.
Option for quick disconnect process connections	3A certified for food and dairy applications
Internal grounding	Simplifies installation, particularly in non-conductive pipes; eliminates the need for separate grounding rings or straps.
