Full Profile Insertion Flowmeter Ideal for Municipal Water or Wastewater Treatment

August 3, 2010

The new full profile insertion flowmeter features additional sensing electrodes for increased sensitivity and is 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 flowmeter with hot tap installation installs without interrupting service, de-watering lines, cutting pipe or welding flanges. The meter’s compact insertion design fits in confined spaces with limited access and offers total accessibility. The flowmeter can be removed in pipes under pressure for easy inspection, cleaning, calibrating or verification with the manufacturer’s own NIST traceable Calibration Lab. The flowmeter’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 flowmeter is available for line sizes from 4 to 138 inches and rivals the performance of a full-bore electromagnetic flowmeter. With highly stable measurement, the FPI Mag™ features accuracy of 1-percent of reading ± 0.03 ft./sec zero stability from 0.3 to 20 ft/s velocity range. The flow sensor comes pre-calibrated from the NIST traceable Calibration Lab and requires no recalibration in the field. The flowmeter 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.
