1. using water at 70 F 21 C This K factor may be used for single point calibration and provide acceptable accuracy However readings may not be accurate when using this calibration method in some situations One example is when using the meter under extreme temperature conditions or with fluids other than water For improved accuracy under such conditions we recommend that a K factor specific to the application be determined and used for calibration A single point calibration may yield acceptable accuracy in the middle of the flo range but five or more calibration points may yield a high level of accuracy especially at the lower end of the flow range 5 MAINTENANCE Proper handling and care will extend the life and service of the meter Turbine Rotor The meter is virtually maintenance free However it is important the rotor moves freely Keep the meter clean and free of contaminants If the rotor does not turn freely apply a penetrating lubricant on the rotor shaft and bearings Remove any debris or deposits from the rotor using a soft brush or small probe Be careful not to damage the turbine rotor or supports Caution Blowing compressed air through the turbine assembly could damage the rotor Battery Replacement The computer display is powered by two 3 volt lithium batteries which may be replaced while the meter is installed ASSURED AUTOMATION When batteries are removed or lose power the batch a2.
