The FPI Mag meter from McCrometer saves on installation costs
The FPI Mag from Hach's Flow Solutions by McCrometer is a hot tap, full profile insertion mag meter for pipes ranging from 4-inches to 138-inches in diameter.
"Instead of an insertion meter like a normal mage meter where you have all your electrodes inside the pipe, you don't have to cut out the pipe," said Corey Christensen, McCrometer regional sales manager. "You can just hot tap this in. It's a 2-inch hot tap."
The FPI Mag is a Build America Buy America-compliant mag meter that uses Faraday's law of electromagnetic induction to measure flow. Running the length of meter on the inside of pipe are electromagnetic coils that produce magnetic fields. As water moves through those magnetic fields it produces voltage that is directly proportional to the velocity of the conductor.
The voltage produced by the water is collected from stainless steel eletrode pairs running along the outside of the entire sensor, and that voltage is then transmitted to electronics that convert the voltage to flow velocity. By multiplying the average flow velocity by the cross-sectional area of the pipe, the device can provide a volumetric flow rate.
Since the FPI Mag can be hot-tapped, it saves costs for utilities as trenches are not required for installation. Instead, the unit can be installed directly into the top of the pipe without the need to use heavy equipment such as cranes, nor is the manpower necessary to use that heavy equipment needed for installation.
Accuracy is 0.5% from 1 ft/s to 32 ft/s, and 1% from 0.3 ft/s to 1 ft/s. The epoxy seal is NSF-certified and lifetime guaranteed.
