Accurate flow measurement is often overlooked at a water treatment plant. Many operators look at flow as being what it is. In reality, accurately measuring your plant’s flow(s) is critically important for operational efficiency, from back-washing to chemical dosing and a host of other processes.
At the City of Benicia, CA, plant superintendent Scott Rovenpara takes flow measurement seriously. “Water treatment plants depend heavily on flow,” said Rovenpara in a recent Water Online Radio interview conducted at ACE.15. “Flow measurement is critical whether you’re calculating a production number or measuring the chemicals that you are dosing. At most treatment plants, your chemicals are flow-paced and so if your flowmeters are inaccurate, your dosage isn’t accurate either.”
At Benicia, the flow points are all in line with pipes. Faced with cutting out a section of pipe to insert a full bore mag meter, Rovenpara became interested in McCrometer’s FPI mag flowmeter that doesn’t require long pipe lengths. With multi-ports and measuring different heights, the FPI can be inserted much closer to a 90 or a deflection.
“The FPI is hot tap-able,” explains Greg Webster, Regional Sales Manager for McCrometer. “It is an insertable device and it is accurate. It has the same performance specifications as full bore mag meters.”
