Product Description
Corrosion Resistant And High-Temperature Resistant Electromagnetic Flowmeter
The high-temperature electromagnetic flowmeter is a specially designed instrument for measuring the flow of conductive liquids at high temperatures. Ordinary electromagnetic flowmeters are usually suitable for media not exceeding 80-120℃, while the high-temperature type can stably measure fluids at temperatures above 120℃, and even up to 400℃ or higher.
Measuring Characteristics
-
Based on Faraday's law of electromagnetic induction, it can measure the volume flow of conductive liquids (such as mud, acid and alkali solutions, etc.), and supports high-temperature conditions (up to 500℃) and low-temperature conditions (down to -200℃).
Structural Characteristics
-
High pressure resistance: Some models can withstand up to 42 MPa of pressure.
-
No flow obstructions: There are no moving parts inside the measuring tube, resulting in minimal pressure loss.
-
Diverse materials: Options include Hastelloy, titanium alloy, and other corrosion-resistant and high-temperature resistant materials.
The core differences between high-temperature and standard types
High temperature is one of the main challenges faced by electromagnetic flowmeters. High-temperature electromagnetic flowmeters have been specially designed and reinforced in the following aspects:
| Comparison Item | Ordinary Electromagnetic Flowmeter | High-temperature Electromagnetic Flowmeter |
|---|---|---|
| Lining Material | Usually rubber, polytetrafluoroethylene (PTFE), etc., with a temperature resistance typically <120℃. | Uses PFA (perfluoroalkoxy), ceramics, etc. Ceramic lining can withstand temperatures above 400℃, and is wear-resistant and corrosion-resistant. |
| Electrode Sealing | Regular rubber or Teflon-coated sealing. | Adopts special high-temperature sealing structures and materials (such as high-temperature O-rings, metal gaskets) to prevent medium leakage at high temperatures. |
| Excitation Coil | Regular enameled wire, insulation is prone to aging at long-term high temperatures. | Uses high-temperature insulated wires (such as H-class, C-class insulation) to ensure the coil does not short-circuit or burn out in high-temperature environments. |
| Signal Processing | - | Has built-in temperature compensation circuits to eliminate measurement zero drift and signal distortion caused by temperature changes. |
| Structural Design | - | The sensor part may adopt split or jacketed designs. The split type allows the converter (electronic part) to be installed away from the high-temperature source; the jacketed type can cool the sensor with cooling water. |
High-temperature electromagnetic flowmeters are widely used in the following industries:
-
Chemical industry: high-temperature heat transfer oil, molten salt, high-temperature polymers, concentrated alkaline solutions, etc.
-
Metallurgy: circulating cooling water (high-temperature), quenching liquid, molten metal (special design required).
-
Energy and power: boiler feed water, high-temperature and high-pressure steam condensate, heat supply network.
-
Paper industry: high-temperature pulp, black liquor.
-
Food : hot water and condensate during high-temperature sterilization (CIP/SIP) processes.
-
Solar thermal: flow measurement of molten salt as heat transfer medium.
High-temperature electromagnetic flowmeters are a reliable solution for measuring high-temperature conductive liquids in industrial processes. The key to successful application lies in precise selection based on specific process conditions, especially temperature, corrosiveness and pressure, and strict compliance with operating procedures during installation and use. When making a selection, it is essential to communicate fully with a reliable instrument supplier and provide detailed information about the working conditions.
