High temperature flow meter are used for measuring the flow of high temperature fluids. The term “high temperature” refers to temperatures exceeding 60-70°C, the typical range of inlet water temperature in many industrial plants. High temperature flow meter are available in many designs. Still, they all have one thing in common: they use some fluidic sensing element to monitor the fluid velocity and pressure changes as it passes through a tube or pipe.
What Is High Temperature Flow Meter
A high temperature flow meter is a device that measures the flow rate of a fluid flowing through it. The term “high temperature” can be confusing because it does not mean that all high-temperature flow meters are used in extremely hot environments.
A high-temperature flow meter has been designed to function well under higher temperatures than other types of meters. These devices are used to measure the flow of fluids, such as water, oil, gas, and steam, at temperatures ranging from 0 degrees Celsius (32 degrees Fahrenheit) to 250 degrees Celsius (482 degrees Fahrenheit).
Working Principle of High Temperature Flow Meter
The working principle of high temperature flowmeter differs from the conventional flow meter. The main difference between them is that in a conventional flow meter, the measurement occurs using two orifice plates, also called corrugated plates. This indicates that there will be air velocity or liquid velocity on each plate, which causes fluctuations in pressure and temperature on both sides of the plate, according to Bernoulli’s principle (Raymond). To measure these pressure fluctuations, sensors need to detect them (Raymond). On the other hand, in high temperature flow meters, use only one orifice plate instead of two corrugated plates, as mentioned above (Bauer). This type of measuring system has been used since early times and was initially introduced by Robert Hooke (De Haan et al., 2005).
The working principle behind both types is similar but differs because they use different kinds of materials, such as metal versus plastic respectively (De Haan et al., 2005). Due to this difference, it becomes essential for users who have been using conventional meters before switching to this new technology called “high-temperature” because some parts may not fit together properly if not careful enough when installing them together!

High temperature flow meters are used for measuring the flow of high temperature fluids.
High temperature flow meters are used for measuring the flow of high temperature fluids. These types of meters can be used in refineries, power plants, and other industrial facilities to measure the flow of hot water, steam, and other fluids.
They are typically installed at critical points in any process. They can measure flows from zero to several thousands of gallons per minute (GPM) without a significant increase in temperature or pressure drop across the meter. This allows measurements that are more accurate than those obtained with conventional strain-gauge type instruments, which have a limit on their maximum capacity due to thermal expansion effects on materials used inside them.
Conclusion
The high temperature flow meter is a device used to measure fluids’ flow. These are very common in industries that deal with heat transfer, oil refineries, and chemical plants. They are also used in power plants for measuring steam flow rates.
