2020 High quality Smart Watt Meter - YUANKY DN15 DN20 DN25 non-magnetic pulse water meter smart water meter without magnetic pulse – Hawai Detail:

Product Features

With self-maintenance function, it can guarantee that only one pulse signal can be sent out for every 360 degree rotation of special magnetic needle.The remote water meter has the function of self- resolution of magnetic interference, which can effectively overcome the weakness of critical point such as water hammer phenomenon and prevent external magnetic interference.

High precision: the measuring precision conforms to ISO4046 standard, and the transmitting signal has no error.

It is suitable for all national standard water meters to meet the technical requirements of different meter reading systems. The output pulse width of remote water meters is greater than 80ms.

Strong anti-interference ability: stainless steel shell, equipped with stainless steel hose protection, to prevent human injury.The self resolving function of magnetic interference makes the long distance water meter work normally under the condition of artificial strong magnetic interference, and the life of magnetic needle can reach more than 6 years.
