McCROMETER SPI Mag Electromagnetic Flow Meter with Procomm Converters


McCROMETER SPI Mag Electromagnetic Flow Meter with Procomm Converters | Ideal for Clean or Dirty Water Flow Measurement


The SPI Mag™ (Single Point Insertion) Electromagnetic Flow Meter is a hot tappable single point insertion flow meter for measuring forward flow. The sensor is available for oneinch or two-inch taps, depending upon line size and application.

The SPI Mag is a cost effective flow meter solution with a purchase price that is independent of line size making the cost to meter a sixty-inch line the same as a two-inch. The SPI Mag’s hot tap installation allows for uninterrupted service as it installs without system shut-down, de-watering lines, cutting pipe or welding flanges. Installation costs are reduced by eliminating the need for heavy equipment or extensive manpower. The SPI can be easily re-located to various line sizes.

Features Typical Water Applications
