　　2、 Main features of the product

　　No mechanical movable parts, not easily corroded, stable and reliable, long service life, long-term operation without special maintenance;

　　Using 16 bit computer chips, high integration, small size, good performance, and strong overall functionality;

　　The intelligent flowmeter integrates a flow probe, microprocessor, pressure, and temperature sensors, and adopts a built-in combination to make the structure more compact. It can directly measure the flow rate, pressure, and temperature of the fluid, and automatically track compensation and compression factor correction in real time;

　　The use of dual detection technology can effectively improve the strength of detection signals and suppress interference caused by pipeline vibration;

　　The flowmeter head can rotate 360 degrees, making installation and use simple and convenient;

　　Cooperate with our company's FM type data collector to enable remote data transmission via the internet or network;

　　Pressure and temperature signals are sensor inputs with strong interchangeability;

　　The whole machine has low power consumption and can be powered by internal batteries or external power sources.

　　3. Installation

　　On site installation and maintenance must comply with the warning message "Do not open the lid when there is explosive gas", and turn off the external power before opening the lid.

　　2. The selection should be within the specified flow range to prevent overspeed operation, in order to achieve ideal accuracy and ensure normal service life.

　　To prevent damage to pipelines and instruments caused by instantaneous airflow impact, the front valve should be slowly opened before the flowmeter is put into operation, and then the rear valve should be slowly opened. After running the small flowmeter for 1-2 minutes and the instrument is running normally, the rear valve should be fully opened. When closing the valve, it should be slowly closed first and then the valve should not be suddenly closed.

　　4. It is not allowed to open the back cover or change the internal parameters of the flowmeter at will during operation, otherwise it will affect the normal operation of the flowmeter.

　　5. Do not loosen the fixed part of the flowmeter at will.
