CFMG702 SERIES

CFMG702 Multi-Parameter Flow Transmitter

Multi-parameter transmitter 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. Product Features: ■ Medium: gas, liquid ■ Caliber: DN80 ~ DN500 (or user-defined) ■ Measurement: flow, pressure, temperature ■ Accuracy: 0.5% (liquid), 1.0% (gas) ■ Range: see range caliber comparison table ■ Display: double-row LCD, total total, instantaneous flow, pressure, temperature, differential pressure ■ Output: 4-20mA, RS485 optional

Product Overview

CFMG702 series uses a built-in differential pressure primary element to calculate flow while simultaneously measuring pressure and temperature. Advanced compensation algorithms automatically improve measurement accuracy for different media and operating conditions.

Unlike conventional differential pressure flow meters, the CFMG702 integrates flow calculation, pressure measurement, temperature compensation and totalization into one compact transmitter, significantly reducing installation complexity and maintenance requirements.

It is widely used in water treatment, gas distribution, energy systems, chemical processing and industrial automation.
