CFMG702 Intelligent multi-parameter flowmeter using the traditional built-in throttle differential pressure principle, when the fluid flows through the throttle will produce a certain differential pressure, through the measurement of the differential pressure value converted to the corresponding flow rate, while the internal circuit can also be measured on the pressure, temperature parameters, and then through the multiple compensation algorithms ultimately derived from the quality of the flow rate, is a practical and economical flowmeter with a micro-intelligent flow measurement system.
