FLOW RATE TRANSPARENCY

Waterco FloVis ensures energy efficiency and adequate flow
Variable speed drive pump and motor technology has transformed the way the pool and spa industry and householders think about energy efficiency. And with the advent of variable speed drive technology, Waterco identified the need for a device which would ensure sufficient water flows to ensure the pool water is adequately filtered and sanitised.
Enter the Waterco FloVis®, hailed as the most advanced, affordable and reliable precision flow meter for swimming pools, spas, fountains and water features.
“While most pumps are tuned via their rpm, we have found many people are unaware of what the flow rate is, so the FlowVis provides this information,” says George Flory, Waterco’s Domestic Water Care Product Manager.
“Significant levels of savings can be achieved by variable speed pumps, but the rest of the pool system also plays a role. The FlowVis enables users to tune their pump to be energy efficient, yet provide adequate flow to the pool, which leads to adequate turnover, filtration and sanitisation.”
The FlowVis® connects into either a 50mm or 65mm PVC pipe. It can be used either as a permanent or temporary installation, and it’s the ideal valve to install in conjunction with variable/multi-speed pumps.
“This will enable accurate pump operating speed adjustments to ensure sufficient water flows to the pools filtration and sanitising equipment,” Flory explains.
“The FlowVis® can also be used by a pool service technician as a temporary connect when they are installing and adjusting pool equipment as variable/multi-speed pumps and even pool, heating equipment when setting up to ensure particular flow rates are achieved.”
Checks and balances
In addition to operating as a flow meter, the FlowVis® is also a fully functioning check valve. As flow increases and decreases, the check valve’s flapper swings within its range of motion. The product features a specially designed calibration spring, indicating arm and an extended height valve body lid.
The FlowVis® is also the first flow meter to be tested and certified to NSF50, with the process confirming average accuracy within just 2.01 per cent between 76 and 416 LPM across all certified models.
“Ordinarily, a significant premium would be paid for this level of precision; however, FlowVis® costs far less than other flow meters which come even close to this level of performance,” Flory says.
In addition, the FlowVis has been designed for installation flexibility top of mind; it can be installed horizontally, vertically or even upside down.
