Second, the principle:

Start when the airflow into the meter, the first fluid through the leading independent movement and accelerated under the action of the fluid, and the fluid flow due to the turbine blades at an angle, then the rotational torque generated by the turbine, the turbine torque and friction torque to overcome the resistance after rotation of equilibrium is reached when all the torque, speed constant, the turbine rotation angular velocity and flow rate is linear. using electromagnetic induction principle, by the rotation of the turbine-driven generator to the top guide magnet reluctance changes periodically, so that the magnetic field changes accordingly, thereby induced across the coil and the volume of fluid flow proportional to the pulse signal. The signal is pre-amplified, after plastic with a pressure sensor, temperature sensor detects pressure and temperature signals are simultaneously input to the flow totalizer calculation process directly shows the instantaneous flow and volume total volume standards.

Six Caution:

• Do meter line welded pipe flange;

• The installation should be preceded by the flowmeter of debris inside the pipe, welding slag, dust clean;

• For ease of maintenance, does not affect the normal fluid transport, the proposed press the map set up a bypass pipeline;


• The flowmeter with superior performance dedicated rectifier, so the straight pipe requirements low just before the straight pipe ≥2DN, after the straight pipe ≥1DN.;

• To prevent the magazine into the flow, you must install a filter;

• The flowmeter should be installed horizontally; vertical installation required, when required ordering;
• When the meter horizontal installation is recommended after installation of the meter straight pipe steel expansion joints, expansion joints must conform to nominal diameter and nominal pressure pipeline design requirements;
• When the flowmeter is installed outdoor use, it recommended that with shields;
• meter around can not have a strong external magnetic field interference and strong mechanical vibration;

• The flowmeter need reliable ground, but not shared with the strong electrical system ground.
