The SPI Mag insertion flowmeter provides a cost-effective solution for the accurate measurement of liquid flow in closed-conduit, pressurized pipe applications. Its cost is independent of pipe size. The meter utilizes velocity and pipe diameter information to determine flow over wide flow ranges with a high degree of accuracy. It reliably measures flow in water and wastewater, as well as any type of industrial flow processes involving conductive fluids, such as potable water, slurries, sludge, cooling water and pulp stock.
