Magnetic flow sensors convert the velocity of a flowing fluid, waters for example, into a measurable electrical signal that is proportional to the flow rate. ...
When it comes to metering water flow — drinking water or wastewater — full-bore mag meters offer many advantages. While the underlying technology based on Faraday’s Law of electromagnetic induction (Figure 1) is shared among all styles of full-bore mag meters, specific implementations have impacts on longevity and accuracy. Here is what to look for when the time to choose ...
Introduction ENVEA have been at the forefront of environmental monitoring and process control over four decades and with the emergence of the Industrial Internet of Things (Industry 4.0) ENVEA are again providing innovative solutions which harness the potential of this new industrial era. In this series of articles, we will be exploring the relationship between industrialisation and ...

By sensing the number of vortices per unit time passing by the velocity sensor, the flowmeter is able to compute the fluid's volumetric flow rate. ...
King who, in 1914 [1], published his famous King's Law revealing how a heated wire immersed in a fluid flow measures the mass velocity at a point in the flow. He called his instrument a "hot-wire anemometer." The first application of this technology was hot-wire and hot-film anemometers and other light-duty TD flow ...

We use both the Stingray portable flow meters and the permanent Area Velocity Flow Meter (AVFM II) in multiple stormwater applications. We have used these meters to measure stormwater flows to help our design engineers develop flow capacity for stormwater projects. ...
Application Steel cast pipe with 700 mm diameter Full filled Existing EMF in pipeline defective Definition of tasks Cost-efficient installation of the new flow measurement Defective EMF should not be removed if possible (costs) No interruption of running processes Solution A permanent flow measurement transmitter Type NivuFlow 750 in ...
The NIVUS COSP technology is a method that permits to calibrate and to adjust flow velocity measurements even under poor flow conditions. This calibration can be carried out based on the cross correlation method using the new NivuFlow 750 M9 transmitter in combination with up to nine flow velocity ...
The method described in this paper solves the problem of variable composition via a new four-temperature mass flow sensor. The new (low sensor feeds its measurements into the algorithms of an advanced mathematical model that includes gas properties in its calculations. ...
Since a volumetric flow rate changes with variations in temperature and pressure, a volumetric flow meter, such as a typical orifice plate, must be compensated with additional temperature and pressure sensors and must use a flow computer to compute mass flow. ...

Task Online measurement of water level and velocity of flow with subsequent discharge calculation according to the velocity-index-method. ...
Abstract This paper describes an advanced microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and has a dry velocity sensor that uses no potting materials instead of the traditional potted ...
Abstract Part 1 of this two-part series describes the principle of operation of a new microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor and has a dry velocity sensor. ...
