Calling it the successor to its earlier Multi-Mag insertion flow meter, which, it claims is the industry’s only multi-electrode hot tap full profile insertion flow metre, McCrometer has introduced the FPI Mag (full profile insertion) electromagnetic flow metre.
According to McCrometer, the new flow metre features additional sensing electrodes for increased sensitivity, and is now packaged in a heavy-duty 316 stainless steel sensor body for maximum structural integrity. In addition, says McCrometer, that the sensor is coated with a NSF certified 3M fusion-bonded epoxy coating for operational longevity.
The manufacturer further claims that the FPI Mag with hot tap installation, not only addresses the need for municipalities to provide uninterrupted service but also improves process control and ensures delivery accountability.
McCrometer lists the following features and advantages of its new product:
- Installs without interrupting service, de-watering lines, cutting pipe or welding flanges
- Reduces installation costs by more than 45% by eliminating the need for heavy equipment or extensive manpower
- The compact insertion design fits in confined spaces with limited access and offers total accessibility
- The flow metre can be removed in pipes under pressure for easy inspection, cleaning, calibrating or verification with McCrometer’s own NIST traceable calibration lab
- Cost-effective for retrofit applications replacing flow meters or in sites never metered before
- The 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 the pipe
- It is available for line sizes from 4 to 138 inches
- Features accuracy of ±1% of reading ± 0.03 feet per second zero stability from 0.3 to 20 ft/s velocity range
- The flow sensor comes pre-calibrated from the manufacturer’s NIST traceable calibration lab and requires no recalibration in the field
McCrometer adds that with single-piece design and no moving parts, the FPI Mag’s multi-electrode sensor contains nothing to wear or break, and is generally immune to clogging by sand, grit or other debris.
It claims that the product supports liquid flow measurement requirements in municipal water and effluent wastewater treatment.
