Schematic view of a flow sensor. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and ...
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 ...
Sonar flowmeters have the capacity of measuring the velocity of liquids or gases non-intrusively within the pipe and then leverage this velocity measurement into a flow rate by using the cross-sectional area of the pipe and the line pressure and temperature. The principle behind this flow measurement is the use of underwater acoustics.
For free flow, the equation to determine the flow rate is simply Q = CH a n where: Q is flowing rate (ft 3 /s) C is the free-flow coefficient for the flume (see Table 1 below) H a is the head at the primary point of measurement (ft) (See Figure 1 above) n varies with flume size (see Table 1 below) Parshall flume discharge table for free flow ...
A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.
Unlike banks, which rely more on deposits to make loans, Affirm and many of its peers opt for a variety of funding models, including warehouse facilities, asset-backed securitizations and so ...
1. Tennis Ball. Tennis balls are so useful that you may want to buy some to keep around the house even if you don’t play. For example, half a tennis ball can help screw open tight caps.
The intro should say what it is, what it does, when it is used. NickelShoe 16:38, 14 February 2006 (UTC) []. Multiple problems with this article. Doppler is not a 'recent' developement, as far as I know it is the oldest ultrasonic flowmeter technology and mostly discredited or at least highly unpopular with most knowledgable flowmeter engineers in industrial applications.
