The thermodynamic method is used for performance testing of pumps, flow meter calibration, system curve tests, and other applications. It is capable of achieving results with uncertainties of less than 1% in pump efficiency and less than 1.5% in flow [ 3 ] while being able to test piping configurations where other conventional pump testing ...
A velocity-type meter measures the velocity of flow through a meter of known internal capacity. The speed of the flow can then be converted into a volume of flow to determine the usage. There are several types of meters that measure water flow velocity, including jet meters (single-jet and multi-jet), turbine meters, propeller meters and mag ...
It was awarded the Flow Control Innovations Award in 2011. [2] Sage Metering was the first thermal flow meter manufacturer to provide a unique and easy to invoke on-site calibration verification. [3] (This saves time and money since the user does not have to remove the meter and return it to the factory (or a third party) for annual flow meter ...
Ultrasonic flow meter; Mass flow meter (Coriolis force). Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area.
Balancing is the methodical regulation of system fluid flows (air or water) through the use of acceptable procedures to achieve the desired or specified design airflow or water flow. When beginning the balance of a system, you must locate the terminal with the least amount of flow in regards to the engineer's drawing.

A fully developed flow profile was used as the reference state for meter calibration and determination of Coefficient of Discharge (Cd). For Reynolds Number 10 5 {\displaystyle 10^{5}} to 10 6 {\displaystyle 10^{6}} n is approximately 7.5; for Re of 10 6 {\displaystyle 10^{6}} , n is approximately 10.0 where a fully developed profile in a ...
The mass flow of a U-shaped Coriolis flow meter is given as: Q m = K u − I u ω 2 2 K d 2 τ {\displaystyle Q_{m}={\frac {K_{u}-I_{u}\omega ^{2}}{2Kd^{2}}}\tau } where K u is the temperature dependent stiffness of the tube, K is a shape-dependent factor, d is the width, τ is the time lag, ω is the vibration frequency, and I u is the inertia ...
