Insertion Mag Meter Installs Without Service Interruption

June 9, 2017
Product features multi-electrode sensor

The FPI Mag is the industry’s only available hot tap full profile insertion flowmeter. It installs without service interruption, making it ideal for retrofits, upgrades and maintenance projects, as well as sites never metered before. The hot tap featured design significantly reduces installation time by eliminating the need to dewater lines or cut pipe, saving customers up to 45% of the total installed cost.

The FPI Mag flowmeter is available for forward-flow only or bidirectional measurement in line sizes from 4 to 138 in. Its flow sensor comes pre-calibrated from McCrometer’s NIST traceable calibration lab and requires no recalibration in the field.

Unlike other insertion mag meters, which only have a single point of measurement, the FPI Mag flowmeter’s advanced multi-electrode sensor compensates for variable flow profiles, including swirl and turbulent conditions. The electrodes, which are placed across the entire sensor body, continuously measure and report the average flow rate across the full diameter of the pipe, delivering accuracy comparable to the performance of a full-bore mag meter.

Multi-point sensing technology makes the FPI Mag flowmeter suitable for cramped plant retrofit equipment layouts or confined space areas with limited straight pipe run availability. The sensor's body also is hermetically sealed and protected by NSF-certified 3M fusion-bonded epoxy coating.

The FPI Mag flowmeter supports liquid flow measurement requirements in municipal water plant applications, including distribution, wells and booster stations, disinfection dosing, filter balancing, and backwash and effluent. Wastewater applications include effluent treatment and recycle/reclaim. Click here to learn more about the FPI Mag.
