  • The advantages of multivariable vortex flowmeters

    Faced with less time and personnel to devote to an increas- ing range of control and measurement problems, engineers must often weigh the cost of inaccuracy against the initial and maintenance costs of flowmeters. This demand for higher accuracy and lower cost over the lifetime of the device is driving the development of enhanced functionality. Most of the recent innovations in flowmeter ...

  • How Does a Thermal Flowmeter Work?

    A thermal flowmeter works by measuring the total mass flow rate of a fluid flowing through a pipe or duct. In a thermal flowmeter’s simplest working configuration, fluid flows past a heated thermal sensor and a temperature sensor. As the molecules of the fluid flow past the heated thermal sensor, heat is lost to the flowing fluid. The thermal sensor cools down while the temperature sensor ...

  • Gas Mass Flow Control: Why Thermal Mass Flow Technology is Recommended for Best Accuracy!

    It’s no secret. Price, but perhaps more importantly, performance, drive every new product acquisition you make.  How important is measurement accuracy and control to your lab experiment or industrial process? It’s critical.  If your flow readings are off or the flow is not controlled with precise accuracy your research is compromised, product quality suffers, and processes ...

  • Sensor design the key advantage in thermal mass flow meter performance

    Immersible thermal sensors arc finding growing acceptance in the gas flow measurement field. By using two Platinum Resistance Temperature Detectors (PRTDs) immersed in a stream of flowing gas, modern thermal flow meters can directly measure mass flow, without the need for temperature or pressure compensation. Thermal meters offer very high turndown, accu- racy and repeatability at an economical ...

  • Industrial thermal mass flow meters Pt.1 -Pt.2 - measurement & control

    An industrial thermal mass flowmeter measures either the mass velocity at a point in a flowing gas or the total mass flow rate through a channel or pipe. Figure 1 shows a typical thermal mass flow sensing element. It consists of two sensors: a mass flow sensor and a temperature sensor, which automatically corrects for changes in gas temperature. Both sensors are reference- grade platinum ...

  • Technology white paper: immersible thermal dispersion

    Thermal dispersion mass flowmeters comprise a family of instruments for the measurement of the total mass flow rate of a fluid, primarily gases, flowing through closed conduits. The operation of thermal dispersion mass flowmeters is attributed to L.V. King who, in 1914 (Ref. 1). published his famous King's Law revealing how a heated wire immersed in a fluid flow measures the mass velocity at a ...

  • How Does a Water Flow Meter Work?

    A flow meter works by measuring the amount of a gas, liquid or steam that passes through or around the flow meter sensors. While flow meter sensors work in many different ways, the end goal is the same: Deliver the most accurate and repeatable flow measurements for the specific application, whether for general research, process control or semiconductor processing. Flow meters measure either mass ...
