Steam Flow Meters
Steam Flow Meters
Steam Flow Meters are used to measure the flow rate of steam in various industrial processes. Accurate measurement of steam flow is essential for process efficiency, energy management, and cost control. Steam flow meters must be able to handle the unique properties of steam, including high temperatures and pressures, and the potential for phase changes (condensation). Below is an overview of the different types of steam flow meters, their working principles, applications, and important selection criteria
Key Specification of Steam Flow Meters
1.Flow Range : The range of steam flow rates that the meter can measure. :
○ Units : Typically in kilograms per hour (kg/h), pounds per hour (lb/h), or tons per hour (t/h)
○ Example : 100 to 50,000 kg/h
2.Pressure Range : The operating pressure range within which the steam flow meter can function effectively. :
○ Units : Bars or Pounds per Square Inch (psi)
○ Example : Up to 100 bar or 1450 psi
3.Temperature Range : The maximum and minimum temperatures the flow meter can withstand. :
○ Units : Degrees Celsius (°C) or Fahrenheit (°F)
○ Example : -20°C to 400°C (-4°F to 752°F)
4.Accuracy : The degree to which the meter can measure the actual steam flow. :
○ Typical Range : ±0.5% to ±2.0% of the reading
○ Example : ±1.0% of reading
5.Pressure Drop The loss of pressure as steam passes through the meter. :
○ Units : Pascal (Pa) or inches of water column (inH₂O)
○ Example : 100 Pa or 0.5 inH₂O
