Measuring the flow of liquids in most industrial applications is vital. In some processes, flow, accuracy, and measurements are essential. They can make a difference between making a profit or a loss. However, inaccurate flow measurement can have disastrous results. But before you pick a flow meter for your processes, you must consider the following factors.
1. Pressure and temperature ranges
When choosing a flow meter from manufacturers, you must consider the temperature values. In addition, you need to be sure of the expected minimum and maximum pressure. Also, you must consider sudden temperature changes and if extra measures must be put in place when cleaning or repairing. In addition, it all depends on whether the slug flow will be present for the system to be efficient. Another thing to consider is if the flow will fill the pipe or reverse.
2. Fluid and flow characteristics
• The description of fluids is done considering:
• Pressure
• Conductivity
• Density
• Viscosity
• Allowable pressure drop
• vapor pressure
• Maximum operating temperature
All these are used to define a fluid that the flow meter will measure. Remember that how fluids interact varies from one to the other. So, all details, such as toxicity, presence of bubbles, and light transmission, need to be known. In addition, you need to state if the fluid contains solid, particle size, and fibers.
3. Piping and installation area
Another factor to consider is piping and flow meter location. The direction, material, size, schedule, valves, regulators, and straight pipe run lengths are included in piping. Also, the engineer needs to know if the area is prone to magnetic fields, electric or pneumatic power, or if it’s an explosion hazard. Other things are if the installation in such an area has special requirements such as compliance regulations.
Flow meters are common and essential in many industries. There are essential in helping in measuring the flow of liquids. However, you must consider the temperature ranges, fluid flow characteristics, and installation area before buying. After considering this, you can pick one that will suit the function.
