Yes, an electromagnetic flow meter can measure many conductive liquids at elevated temperatures, provided the selected model is designed for the required operating conditions.
For high-temperature applications, the most important factors include liquid temperature, liner material, electrode compatibility, pressure rating, and transmitter installation.
1. What Applications Require High-Temperature Flow Measurement?
High-temperature electromagnetic flow meters may be used in:
- • Industrial process water systems
- • Heated chemical solutions
- • Hot liquid production processes
- • Industrial wastewater treatment
- • Conductive liquids in manufacturing plants
The liquid must be electrically conductive, and the meter must be rated for the actual process temperature.
2. How Does Temperature Affect an Electromagnetic Flow Meter?
High temperatures can affect the liner, seals, electrodes, and transmitter electronics.
A liner that is suitable for ordinary water temperatures may not be suitable for a hot process liquid. Temperature limits also depend on pressure, meter construction, and whether the sensor and transmitter are compact-mounted or remotely mounted.
Always check the maximum permitted liquid temperature for the complete meter configuration.
3. Which Liner Material Is Suitable for High Temperatures?
PTFE is commonly considered for many chemically demanding and higher-temperature applications. Other liner materials may be suitable depending on the liquid, temperature, pressure, and abrasion requirements.
4. Should You Choose a Compact or Remote Structure?
Both compact and remote-mount configurations may be available, depending on the model.
A remote-mount electromagnetic flow meter can be useful when the measuring sensor is installed in a high-temperature area and the transmitter needs to be positioned elsewhere within its permitted environmental limits.
The maximum sensor temperature, cable specifications, and transmitter ambient temperature must be confirmed before selection.
