Good Hermeticity
Long-term protection of internal components from environmental influences.
Flowmeter Terminal-1 works by providing electrical interconnection and hermetic protection for the internal sensing elements of the flowmeter. The base is made of stainless steel material; the glass-insulated pins are connected to the base through a sintering process to form a hermetic connection.
The internal sensing elements of the flowmeter are mounted on the mounting surface of the base and connected to the corresponding pins by wire bonding. The electrical signals are transmitted through the pins to the external measurement system, and the sensing elements convert the flow information into electrical signals for flow measurement.
The base and the flowmeter housing are welded together to form a hermetic packaging structure, ensuring that the internal sensing elements are not eroded by the measured medium and the external environment, guaranteeing the long-term stable measurement accuracy of the flowmeter.
