McCrometer is to present its FPI Mag – a full-profile insertion flowmeter for municipal water treatment, distribution and storage applications – at AWWA’s ACE11 event on 12-16 June in Washington, DC.

According to the company, which will be found in Booth 1911, the new Model 394L FPI Mag flowmeter offers forward and reverse flow measurement.

The most common applications include storage tanks, water selling or sharing, multiple water sources and ring-main distribution systems.

In addition to locations where water is known to flow in both directions, the new bidirectional flowmeter helps users with complex, problematic piping configurations.

Valuable flow data can now be gathered where measurement was previously cost prohibitive, such as in areas affected by multiple expansions and retrofits or locations where two or more pipes converge and are consolidated into a single line.

With a compact design and easy hot-tap installation, the Model 394L FPI Mag flowmeter is designed for challenging applications with large or irregular piping.

The FPI Mag flowmeter comes standard with an L-Series converter that is calibrated to provide a precise, real-time indication of flow and the totalised flow volume in both forward and reverse directions.

The Model 394L FPI Mag flowmeter is a multi-electrode, hot-tap, full-profile insertion flowmeter that delivers a continuous total flow profile similar to a full-bore mag meter.

It delivers advantages in terms of performance, ease of installation, maintenance and value, according to McCrometer.

Featuring an enhanced design with additional sensing electrodes for increased sensitivity, the Model 394L FPI Mag flowmeter is packaged in a heavy-duty 316 stainless steel sensor body for maximum structural integrity.

The sensor is coated with an NSF-certified 3M fusion-bonded epoxy coating for operational longevity.

The Model 394L FPI Mag flowmeter offers a multi-electrode sensor design, which places multiple electrodes across the entire sensor body.

This design compensates for variable flow profiles, including swirl, turbulence and low-flow conditions, by reporting the average flow rate over the full diameter of the pipe.

With no moving parts and a single-piece design, the FPI Mag flowmeter contains nothing to wear or break and it is generally immune to clogging by sand, grit or other debris.

The Model 394L FPI Mag flowmeter features hot-tap installation, addressing the increasing need for municipalities to provide uninterrupted service while improving process control and ensuring delivery accountability.

It installs without de-watering lines, cutting pipe or welding flanges, thus reducing installed costs in medium and large line sizes by eliminating the need for heavy equipment and extensive manpower.

The FPI Mag flowmeter features a compact insertion design that will fit into confined spaces with limited access.

This design makes it possible to remove the flowmeter in pipes under pressure for inspection, cleaning and calibration or verification.

Thanks to the flexibility the FPI Mag flowmeter provides, it is often used for retrofit applications or in sites never metered before.

The flowmeter is available for line sizes from 4in to 138in and is claimed to rival the performance of a full-bore electromagnetic flowmeter.

With precise measurement, the FPI Mag flowmeter features an accuracy of +/-1 per cent of reading +/-0.03ft/sec zero stability from a 0.3ft/sec to 20ft/sec velocity range in both forward and reverse directions.

The flow sensor comes pre-calibrated from McCrometer’s NIST-traceable Calibration Lab and requires no recalibration in the field.
