The product adds a magnetic steel pointer to the liquid seal counter, which forms a sensor with the module. The pulse acquisition circuit processes the pulse signal into data and stores it. Wireless communication will upload data to the concentrator when needed.
The product is wireless automatic upward transmission. Communication using GSFK or LORA modulation in the radio frequency range of 470M Hz to 510M4iz.
The base table and module are completely separated, making installation and maintenance more convenient; The concentrator issues a command to read the current data of the water meter; The water meter automatically reads the water meter data at regular intervals and uploads it to the concentrator; The protection level of the entire meter is IP68, and it can work normally when immersed in water; The concentrator uses GPRS communication to upload data to the platform.
Calculation parameters and indication error limit (range ratio Q3/Q1=100)
Electrical technical parameters:
Static current: ≤ 8mA;
Dynamic current: ≤ GSFK≤60mAo; LORA≤120mAo
