Reduce Installation Time and Cost: Next Generation Mag Meter Improves Processes

Today's operations managers recognize the need to improve their processes and reduce costs. McCrometer's FPI Mag® Next Generation Mag Meter reduces installation costs up to 45% by eliminating the need for heavy equipment and excessive manpower. This innovative meter provides accuracy that rivals a full-bore mag, plus simple, fast hot tap installation without the need for system shutdown, as well as versatility to meet a wide range of applications and pipe sizes.

The FPI Mag® (Full Profile Insertion) Electromagnetic Flow Meter is the only hot tap full profile insertion flow meter available on the market. The FPI Mag installs without service interruption making it ideal for retrofits, upgrades and maintenance projects and sites never before metered. The hot tap installation significantly reduces installation time eliminating the need to de-water lines or cut pipe.

The multi-electrode sensor delivers an accurate measurement of the full pipe profile rivaling the performance of a full-bore mag meter. The repeatable, stable measurement across the entire flow profile compensates for variable flow profiles, including swirl and turbulent conditions.

The FPI Mag is the industry’s most economical flow metering solution offering unbeatable value in the cost of installation and ownership reducing installed costs by more than 45 percent in medium and large line sizes. The compact insertion design fits in confined spaces and offers complete accessibility. The flow meter can be removed in pipes under pressure for easy inspection, cleaning, calibrating, or verification. Installation costs are reduced by eliminating the need for heavy equipment and extensive manpower.

The innovative flow meter 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 sensor contains nothing to wear or break and is generally immune to clogging by sand, grit, or other debris. The electrodes are encased in a heavy-duty 316 stainless steel sensor body for maximum structural integrity and coated with a NSF certified 3M™ fusion-bonded epoxy coating for operational longevity.
