As a basic example, you could perform a calibration by measuring the temperature of a DUT thermometer in water at the known boiling point (212 degrees Fahrenheit) to learn the error of the thermometer. To calculate the load cell conversion factor (well call it Mcal) used to turn these numbers into useful results, simply divide the change in weight by the change in sensor reading. About 50% of these aredifferential pressureflow meters, 40% is the liquid flow sensor, and 20% are Ultrasonic flow Transmitterand mass flow meter. between 0.3 and 0.5 The axial design of Turbine Flow Meter is inherently linear within a known turndown range, typically 15:1, based on velocity of the measured fluid. As k=1 is not an acceptable standard for reporting uncertainty as it leaves a lot of room for passing erroneous readings. The K value is obtained from an experimental calibration measurement in a phantom using a metabolite of known concentration. A k-value (sometimes referred to as a k-factor or lambda value ) is a measure of the thermal conductivity of a material, that is, how easily heat passes across it. The K-Factor is simply how many degree days it takes for your customer to burn ONE gallon of fuel. KES Machine Tools has been providing high-quality CMM calibration services in Connecticut since 2000.
