Key words: calibration, correlated uncertainty, flow, flowmeter, water flow standard, diverter, mass calibration, meter, uncertainty. A device that measures water quality in this way is called a continuous water-quality monitor. The accuracy of stock inventory depends largely on the accuracy of the calibration data of the various storage tanks and structures deployed along the value chain. These errors can be as large as 10-15% for 5-55°C, where as the target specification is approximately ±1% accuracy.

Master meter method is an efficient way to calibrate flow meters with less time and costs. NETWORK CONNECTIONS** The process of measuring the inside or outside diameter of the tank becomes very important in the tank calibration process-the measurement of tank diameter by the strapping method using steel meters manually. The formalism presented in [1, 2] is often, though unofficially, referred to as the CIPM-81 equation to indicate that its use has been recommended by the Comite International des Poids et Mesures and that 1981 was the year of this recommendation. Testing vertical cylindrical tanks are generally divided into two parts, namely: volumetric methods and geometric methods. �*p>*�$V=��ZiS8\8W�r�Z[��F��,�.

H��n�@��)�e+��BH� In the volumetric method, the standard vessel takes the form of a container with calibrated volume. Another approach is the calibration by volumetric method, using a tank prover as standard. These guidelines explain how water utilities can achieve a good accounting of water production and consumption through the use of large meters. Fill calibration containers with the buffered standards so each standard will cover the pH probe and temperature sensor. �� C�� q" �� the Meter Factor of a meter (factor used with a meter to correct accuracy for ambient conditions). These monitors have sen-sors and recording systems to measure physical and chemical water-quality field parameters at discrete time intervals at point locations. We calibrate a customer's flow meter and deliver a calibration report that documents the calibration procedure, the calibration results, and their uncertainty on a fee-for-service basis.
