Summary:
LZ series metal tube float flowmeter has simple structure, reliable operation, high accuracy and wide application range. It is widely used in the measurement and control of liquid and gas flow in the fields of national defense, chemical industry, petroleum, metallurgy, electric power, environmental protection, medicine, etc.
The electrically remote metal tube float flowmeter produced by our company abandons the contact transmission mode of connecting rod transmission, and adopts the independently developed non-contact intelligent transmitter with MSP as the core CPU, which greatly improves the reliability, stability and accuracy of the instrument.
