Actual to Normalized

When sizing & specifying instruments for gas flow measurement, such as Thermal Mass Flowmeters, Variable Area Flowmeters, or Vortex Flowmeters, actual flows must be converted to normalized flows (or Standard flow) in order to determine if a gas flow meter can be specified for a given application.  This conversion is performed using the ideal gas law.  Gas flow meter users need a reference condition to compare different flows existing at different flowing conditions of pressure and temperature. However, the problem with Normal or Standard conditions is that there are several different pressure and temperature references depending upon whom you talk to.  SmartmeasurementTM’s user friendly normalized to actual or actual to normalized calculators allows our customers the flexibility to use their own reference conditions to come up with the correct answer.  These calculations are frequently used for gas flow measurement applications as a slight change in temperature and/or pressure affects the fluid density.  Please make sure that whatever flows you are comparing, you are using the same reference pressure and temperature conditions.  A good analogy for this type of calculation is exchange rates for the various currencies used around the world, where the conversions are referenced to either the US dollar or the Euro.

Conductivity

Electromagnetic flowmeters provide a number of advantages over other flow measurement technologies including excellent accuracy & repeatability, wide turndown ratios, long service life, and low/no pressure loss. One key consideration when sizing and specifying Mag Meters is that the fluid media must be electrically conductive; typically ≥ 5μS/cm. In order to assist users of Electromagnetic Flowmeters with the task of determining if a mag meter will work in their given application; Smartmeasurement has compiled an industry-leading reference for electrical conductivities of various fluids. In the table below, conductivity values shown in green indicate that the corresponding fluid is suitable for use with a mag meter.   If the conductivity value is red, a mag meter is not suitable and alternate flow measurement technologies should be explored. Conductivity values displayed in yellow are questionable; please contact the SmartMeasurement factory for assistance.

If a particular chemical is not listed, or if you would like application assistance with an electromagnetic flowmeter application, please feel free to contact SmartMeasurementTM’s U.S. offices at 1-866-404-5415 for assistance. Our team of application engineers would be happy to review your application and quote a suitable mag meter at industry-leading prices.

Flow Rate to Velocity

Flow meter users who know what flow rate they need to measure can use this calculator to determine if a flow meter is capable of measuring that flow rate based on the manufacturer’s published velocity measurement specifications. Flow meter technologies such as differential pressure, magnetic, thermal, turbine, ultrasonic and vortex all measure flow rate as a function of fluid velocity. Any flow meter employing one of these technologies will have a published specification for the range of velocities that it is capable of measuring.  By using the flow continuity equation in this section Where: Flow (Q) =V (flow velocity) X A (cross sectional area of the measurement location), engineers can determine both the velocity and/or flow range for any flow meter which employs one of these technologies.

If you need a recommendation for a difficult-to-measure flow application, please feel free to contact SmartMeasurementTM’s U.S. offices at 1-866-404-5415 for assistance. Our team of application engineers would be happy to review your application and recommend one or more suitable technologies at industry-leading prices.
