Abstract

The invention discloses a single light-sensing water meter sensor. A light-sensing electronic element and two light-emitting diodes (LEDs) are arranged inside the sensor, the two LEDs emit flashing light in an alternant mode, two light spots show through irradiation in a water meter dial plate, are arranged in parallel along the rotating trail of a water meter pointer, and mostly overlap with the sensing region of the light-sensing electronic element, and according to the change of diffuse reflection light of the sensing region, the forward and backward rotation states, the transient flow and the accumulated flow of a water meter are obtained. The single light-sensing water meter sensor can achieve all functions of a dual light-sensing type water meter sensor, and is higher in collection accuracy, better in stability and lower in power consumption and cost compared with the dual light-sensing type water meter sensor.

Description

technical field [0001] The invention relates to a water meter sensor, in particular to a water meter sensor which mainly uses a photosensitive electronic element inside the sensor to collect the accumulated flow, instantaneous flow and forward and reverse state of the water meter. Background technique [0002] At present, the known dual photosensitive water meter sensor uses two photosensitive electronic components inside the sensor to collect the operating status of the mechanical water meter. Since the sensing areas of the two photosensitive electronic components are different, and there will be a gap between the two photosensitive electronic components. Sensing error, therefore, may cause a large difference in the optical information actually sensed by the two photosensitive electronic components, which can affect the accuracy and stability of the water meter sensor in severe cases. Due to the need to use two photosensitive electronic components to operate, the dual photo...
