The ACFM mass flowmeter consists of two parts: a sensor and a transmitter. Based on the Coriolis principle, the flow tube passing through the medium vibrates. The sensor detects and analyzes the changes in frequency, phase difference, and amplitude of the flow tube, directly measuring the mass of the medium flowing through the current flow tube. The density is calculated from the vibration frequency. Simultaneously measuring multiple process variables of the medium, such as mass flow rate, volume flow rate, density, and temperature.
1. Directly measure the mass flow rate of the fluid (unaffected by temperature, pressure, velocity distribution, etc.);
2. Multi functional (capable of simultaneously measuring multiple on-site variables such as flow rate, density, temperature, etc.);
3. High accuracy (liquid can reach ± 0.1%, gas can reach ± 0.25%);
4. Long service life and low maintenance rate;
5. Adjustable damping time;
6. It has strong circuit self diagnosis function, which facilitates fault finding.
