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 ...
Because they are used for domestic water measurement, piston meters, also known as rotary piston or semi-positive displacement meters, are the most common flow measurement devices in the UK and are used for almost all meter sizes up to and including 40 mm (1 + 1 ⁄ 2 in). The piston meter operates on the principle of a piston rotating within a ...
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 ...
The firm has 100 employees and over 120,000 sq feet of indoor lab space on a 32-acre campus in Holden, MA, and an additional 25,000 square feet of laboratory space in Redmond, WA. Alden provides engineering, physical and computational flow modeling along with environmental and flow meter calibration services.
Raven Industries, Inc. is an American company that makes precision agriculture products and information management tools for growers. Before a series of acquisitions in 2021, it also had an Engineered Films segment that produced plastic films for various agricultural and industrial applications, as well as an Aerostar Industries segment that designed and manufactured high-altitude balloons ...
Flow is measured using Coriolis meters by analyzing the changes in the Coriolis force of a flowing substance. The force is generated in a mass moving within a rotating frame of reference. An angular, outward acceleration , which is factored with linear velocity is produced due to the rotation.
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 ...
The flow rate is specified as a percentage of its calibrated full scale flow and is supplied to the MFC as a voltage signal. Mass flow controllers require the supply gas or liquid to be within a specific pressure range. Low pressure will starve the MFC of fluid and cause it to fail to achieve its setpoint. High pressure may cause erratic flow ...
