Can the vortex flowmeter still work properly at low temperatures?

Whether the vortex flowmeter can work properly in low temperature depends on several factors, including the design of the flowmeter, material selection, the temperature range of the low-temperature environment and the characteristics of the measured medium. The following is a detailed analysis of the vortex flowmeter’s ability to work at low temperatures:

Flowmeter design and materials

Material selection: the main components of the vortex flowmeter (such as sensors, vortex generator, housing, etc.) are usually made of stainless steel or other low-temperature resistant materials. These materials in the low temperature environment can still maintain good mechanical properties and stability.

Electronic components: flowmeter internal electronic components (such as amplifiers, signal processors, etc.) need to work properly in a low-temperature environment. Modern vortex flowmeter usually adopts wide temperature electronic components, which can operate stably at lower temperatures.

Temperature range for low-temperature environments

Operating temperature range: Different models of vortex flowmeters have different operating temperature ranges. Generally speaking, the working temperature range of vortex flowmeter is between -40°C and +200°C, the specific range should refer to the manufacturer’s technical specifications.

Extreme low temperature: If the ambient temperature is lower than the minimum working temperature of the flowmeter, it may cause the electronic components to fail or the material to become brittle, affecting the normal operation of the flowmeter.

Characteristics of the measured medium

Medium temperature: the temperature of the measured medium will also affect the work of the flowmeter. If the medium temperature is very low, it may lead to media icing or viscosity increase, affecting the measurement accuracy of the flowmeter.

Medium state: in the low temperature environment, the medium may undergo a phase change (such as liquid to solid), which will affect the measurement effect of the flowmeter.

Protective measure

Heat preservation measures: in low temperature environment, can take heat preservation measures for flowmeter and pipeline, prevent the temperature is too low to affect the normal operation of the flowmeter.

Heating device: in the extreme low temperature environment, you can consider using heating devices (such as electric heat tape) to maintain the temperature of the flowmeter and pipeline, to ensure that the medium to maintain the liquid state.

Application examples

Liquefied Natural Gas (LNG): In the transmission and storage of LNG, the temperature is extremely low (about -162°C), which requires the use of specially designed cryogenic vortex flowmeters to ensure normal operation in extremely low temperature environments.

Cryogenic liquids: In the measurement of cryogenic liquids such as liquid oxygen, liquid nitrogen, etc., vortex flowmeters need to have good low temperature adaptability.

Whether a vortex flowmeter can work properly at low temperatures depends on its design, materials, operating temperature range and the characteristics of the medium to be measured. Generally speaking, modern vortex flowmeters are able to work properly in the temperature range from -40°C to +200°C. In extreme low-temperature environments, it is necessary to take appropriate protective measures (such as insulation, heating, etc.) and select specially designed low-temperature vortex flowmeter to ensure its stability and measurement accuracy.

If you need to use the vortex flowmeter in an extremely low temperature environment, it is recommended to communicate with the manufacturer to select the appropriate model and take the necessary protective measures to ensure the normal operation and long-term stability of the flowmeter.
