Please see technologies and process limits downloads – in metric or U.S. ![]() Matching your Application Parameters with a Flow TechnologyĪre the meter’s application parameters such as pipe size, flow rates, pressure, temperature, etc. This website provides a resource to explain the theory of operation for each and the tools to help identify the ideal meter for your situation.Įvaluation of any flow meter for a given application must consider the following:Ī) Does the sensing element contain moving parts that require periodic maintenance?ī) Does the meter contain analog transducers that may drift over time?Ģ. Smartmeasurement TM offers a comprehensive portfolio of all flow technologies to address whatever operating conditions your specific application entails. Other new technologies such as Coriolis or thermal dispersion are capable of measuring mass flow directly which means that they are unaffected by changes in pressure, temperature and viscosity and do not require the real-time compensation. Many newer technology flow meters feature integrated flow computers to compensate for variances in actual process conditions such as pressure drop, temperature, viscosity and density in real time. Finally, there are inferential flow meters that do not measure volume, flow velocity or mass, but rather measure flow by inferring its value from other measured parameters such as differential pressure across a known obstruction, force measured against a target placed in the flow profile, or variable area flowmeters which relate linear displacement of a float with known mass and geometry to the measured flow rate. ![]() Other meters, such as Coriolis and thermal flow meters measure mass flow directly, while only positive displacement flow meters directly measure volumetric flow.
