The remote water meter is also called intelligent remote water meter. The so-called "intelligence" means that the internal structure of the water meter is equipped with intelligent electronic modules. Generally, it has two working principles: pulse type and direct reading type. The pulse type remote water meter is equipped with a sensor on the counter of the meter, which will send a pulse signal every time the word wheel rotates, At this time, the system will collect, accumulate and store each pulse signal, and then conduct remote meter reading on the meter reading machine or upper computer. The main types are photoelectric conversion pulse type, reed tube pulse type and Hall element pulse type. Its biggest advantage is that it is convenient for centralized meter reading management, greatly reduces the labor intensity of meter reading personnel, and has reliability and anti-interference; The direct reading remote water meter is to install several sensing devices on one side of each word wheel of the water meter counter, and install the sensor corresponding to the sensing device on the other side, and then determine the position of the word wheel through the corresponding state of the sensor and the sensing device, so as to obtain the data to be read out, and then conduct remote meter reading through the meter reading machine or upper computer. The main types are transmission photoelectric conversion direct reading type, contact coding direct reading type, reflection photoelectric conversion direct reading type, resistance contact direct reading type and digital camera direct reading type.
Există multe tipuri de apometre inteligente. Pe lângă contoarele de apă la distanță de mai sus, există și unele comune, cum ar fi contoarele de apă inteligente cu card IC preplătite, care se numesc contoare cu card sau contoare cu card magnetic. Acest contor de card este utilizat mai pe scară largă în apartamente, case de închiriere, cămine din fabrici și alte scene. Experiența sa funcțională este mai convenabilă și mai inteligentă atât în utilizare, cât și în administrarea ulterioară.
