FPI Mag™ (Full Profile Insertion) Flow Meter Combines Ease of Hot Tap Installation and Accurate Measurement of Full Flow Profile
Ideal for Municipal Water or Effluent Wastewater Treatment, Retrofit Applications Replacing Meters, Confined Spaces, Locations Never Metered and Large Lines

McCrometer introduces the FPI Mag™ (Full Profile Insertion) Electromagnetic Flow Meter. The new FPI Mag is the successor to McCrometer’s popular Multi-Mag Insertion Flow Meter, which is the industry’s only multi-electrode hot tap full profile insertion flow meter delivering a continuous total flow profile similar to a full-bore mag meter.

The enhanced design of the new Full Profile Insertion Flow Meter features additional sensing electrodes for increased sensitivity and is now packaged in a heavy-duty 316 stainless steel sensor body for maximum structural integrity. The sensor is coated with a NSF certified 3M fusion-bonded epoxy coating for operational longevity.

The FPI Mag with hot tap installation addresses the ever increasing need for municipalities to provide uninterrupted service 24/7, but at the same time improves process control and ensures delivery accountability. The Full Profile Insertion Flow Meter from McCrometer installs without interrupting service, de-watering lines, cutting pipe or welding flanges. Installation costs are reduced by eliminating the need for heavy equipment or extensive manpower. The FPI Mag is the industry’s most economical flow metering solution for medium and large line sizes, reducing installed costs by more than 45 percent.

The FPI Mag meter’s compact insertion design fits in confined spaces with limited access and offers total accessibility. The flow meter can be removed in pipes under pressure for easy inspection, cleaning, calibrating or verification with McCrometer’s own NIST traceable Calibration Lab. It is particularly cost-effective for retrofit applications replacing flow meters or in sites never metered before.

Unlike all other insertion mag meters, the FPI Mag Flow Meter’s multi-electrode sensor design compensates for variable flow profiles, including swirl, turbulence and low-flow conditions. Multiple electrodes placed across the entire sensor body continuously measure and report the average flow rate over the full diameter of pipe.

The Full Profile Insertion Flow Meter is available for line sizes from 4 to 138 inches and rivals the performance of a full bore electromagnetic flow meter. With highly stable measurement, the FPI Mag features accuracy of ±1% of reading ± 0.03 ft./sec zero stability from 0.3 to 20 ft/s velocity range. The flow sensor comes pre-calibrated from McCrometer’s NIST traceable Calibration Lab and requires no recalibration in the field.

With no moving parts and a single-piece design, the FPI Mag’s multi-electrode sensor contains nothing to wear or break, and it is generally immune to clogging by sand, grit or other debris. The FPI Mag supports liquid flow measurement requirements in municipal water and effluent wastewater treatment. Typical municipal water applications include: wells, booster stations, effluent, filter balancing and backwash, pumping stations, UV dosing and potable water distribution.
