Second, the principle:

As shown, the fluid flows through the sensor housing, since the flow impeller blade with a certain angle, the momentum of the fluid has a rotational torque of the blade, the blades rotate after overcoming the friction torque and fluid resistance, the speed in the torque balance and stability, in magnetic field under certain conditions, speed and velocity is proportional, because the leaves have permeability, it is a signal detector (by the permanent magnet and coil), the rotation of the blades cutting magnetic field lines, periodically changing the coil of the magnetic flux, so that both ends of the coil induces an electrical pulse signal which is amplified shaping amplifier is formed with a certain level of continuous rectangular pulse wave, can be remote to the display instrument, showing the instantaneous flow rate and cumulative amount of fluid. In certain within the flow range, pulse frequency f and instantaneous flow of the fluid flowing through the sensor Q proportional to the flow rate equation is: Q = 3600 * f / k;

Where:

f- pulse frequency (Hz);

k- sensor meter factor (1 / m 3 ), Is given by a single calibration. In terms of (1 / L) as a unit

Q- instantaneous flow of fluid (operating condition) (m3/h) ;

3600- conversion factor.

Each sensor meter factor from the factory fill in the verification certificate, k value is set into supporting the display instrument, it can display the instantaneous flow rate and cumulative totals.

Six Caution:

• When using, keep the liquid under test clean, free of fibers and particles and other impurities.

• sensor at the beginning of use, the sensor should first slowly filled with fluid, and then open the outlet valve (the valve should be installed in the meter backend), high-speed non-impact sensor in fluid when no liquid state.

• sensor maintenance cycle is generally six months. Overhaul cleaning, take care not to damage the measurement chamber parts, especially the impeller. Please promising positional relationship between the guide and the impeller assembly.

When the sensor is not in use, clean the inside of the liquid, and after drying at both ends of the sensor plus the protective cover to prevent dust entering, and then placed in dry place. (This is very important)

• Equipped with the filter should be cleaned regularly, do not be cleaning the inside of a liquid, like sensors, plus dust cover in a dry place to save.

• sensor transmission cable can be laid overhead or underground (buried iron pipe should be put on.)

• Before installing the unit, first with the display instrument or oscilloscope connected wires, through power, with mouth-blown or hand dial impeller to rotate quickly to observe whether the display when a display before installing the sensor. If there is no display, you should inspection of the various parts, troubleshooting.
