Description

The GPI G2 Series Water Flow Meter is engineered to deliver precision and reliability in measuring water-like fluids across a range of industrial and commercial applications. With a meter body size of 2" and a local digital LCD display, this meter allows for easy reading of flow rates and totals—both batch and cumulative. Designed for optimal performance, the G2 Series offers impressive factory calibration accuracy of ±0.75%, along with a repeatability of ±0.1%, ensuring highly reliable flow measurements. It is equipped to handle maximum pressures of up to 1500 PSI and operates effectively in a wide temperature range from -40 to 250°F (-40 to 121°C). This flow meter includes several advanced features: it is factory calibrated and field calibratable, provides both resettable and cumulative total measurements, and allows configuration for either gallons or liters. The display is user-friendly, featuring a 6-digit floating decimal configuration that offers clarity in readings. Durability is a hallmark of the G2 Series, with housing made from 316SS and bearings crafted from 96% alumina ceramic and tungsten carbide. The meter is capable of operating accurately under varying flow conditions, with an extended flow range of 200 to 300 GPM (760 to 1136 LPM), though users should note that accuracy outside normal conditions may decline. Moreover, it includes options for remote output through 4-20mA or pulse signals, enhancing its versatility for integration into existing systems. Despite its robustness, maintenance is painless with replaceable internal meter components and an included 1-year warranty. However, potential users should be aware that this meter is not suitable for deionized water or oils exceeding 100 cps viscosity. For optimal accuracy, it's recommended to maintain complete fluid lines, avoiding air pockets, and adhere to specified straight pipe diameters.
