Rotor flowmeter
Intelligent metal rotor flowmeter is a variable area flow meter based on float position measurement. Adopting all-metal structure, with small volume, small pressure loss, large range ratio (10~ 20:1), optional transmitter with HART communication function, easy installation and maintenance, etc., widely used in various industries complex, harsh environment, small flow rate, low flow rate, a variety of harsh medium conditions flow measurement and process control.
Feature
1. Strong all-metal construction design.
2. Suitable for gas and liquid measurement in various industries
3. New case structure design, no additional components can be used in high temperature environment.
4. Flange, clamp, thread and other process connection methods are available, suitable for most factory applications.
5. Specially designed tapered measuring tube has a wider measuring range and better measuring linearity.
6. Measurement part of the material optional: stainless steel, titanium, Hastelloy alloy, PTFE, FEP and other materials.
7. The specially designed magnetic coupling system can obviously improve the accuracy and stability of measurement.
