product appearance


product presentationNon-magnetic pulse water meter is a non-magnetic long-distance water meter with no
permanent magnet and other magnetic components inside, which is less affected by internal and external magnetic force. It can measure the speed and judge the rotation direction by using the principle of LC oscillation, detect the distance and measure accurately.
Non-magnetic water meter is mainly composed of base meter, non-magnetic sensor, remote control module, battery and other accessories. It adopts electromechanical separation structure, and the sampling unit can be as small as the water meter with liter accuracy.

Non-magnetic remote transmission module can be in need of remote transmission, later installation, set the water meter base number (mechanical table has run water, to set the number of electrons in the module, so that mechanical reading and electronic reading is consistent) and can be used when enabled.
Technical proposal:There are several red Pointers for metering on the water meter (including the water meter body)；Any red pointer on the water meter body is provided with a semicircle steel sheet coaxially；The semicircular steel sheet rotates synchronously with the rotating shaft of the red pointer；The position of the corresponding semicircle steel sheet above the glass of the water meter body is provided with a rotation signal acquisition device；The rotating signal acquisition device comprises a signal acquisition sensor coil and a signal processing circuit；The signal acquisition sensing coil comprises an external inductance coil and four inductance coils uniformly arranged within the external inductance coil；The outputs of the four inductance coils are connected to the signal processing circuit.
Measurement introduction:No magnetic pulse: pulse type remote meter measuring water flow in pipes, water meter in
the microcomputer automatic storage of water use, when the timing to send data to the time or have the meter signal detected, through wireless spectrum data are sent using spectrum is the WuWei will be issued special meter frequencies, there would be no interference, instead of manual meter reading, and more convenient, more efficient and meter high success rate.

product superiority
1 With self-maintaining function, the self-maintaining function can ensure that the special magnetic needle can only send out a pulse signal every 360 degrees of rotation. With the self-resolving function of magnetic interference of the remote water meter, it can effectively overcome the weakness of the critical point such as water hammer phenomenon, and has the function of preventing external magnetic interference.
2 High accuracy: the measurement accuracy is in accordance with ISO4046 standard, and there is no error in the transmitted signal.
3 High versatility: applicable to all national standard water meters, can fully adapt to the technical requirements of different meter reading system, far water meter output pulse width is greater than 80ms.
4 Strong anti-interference ability: stainless steel shell, with stainless steel hose protection, to prevent human damage. The magnetic interference self-solution function enables the remote water meter to work normally in the case of artificial strong magnetic interference, and the magnetic needle life can reach more than 6 years.
5 Without damaging the structure and performance of ordinary water meter, the whole remote water meter can reach the performance index of ordinary water meter.
6 Signal transmission mode: passive switch on and off, with short line alarm function, according to customer needs, can use two or three wire system and remote water meter outdoor display device combination reading more convenient.
7 Long service life. The whole remote expressed to the ordinary meter life, the remote part can be used for ten years.
