Embodiment Construction

[0014] The present invention will be described in further detail below according to the drawings and embodiments.

[0015] figure 1 It is the schematic circuit diagram of the electronic water meter of the present invention, figure 2 For the luminous tube state diagram of the present invention, refer to figure 1 , figure 2 ,this invention:

[0016] An electronic water meter comprises a control port 1 (1), a control port 2 (5), a control resistor 1 (2), a control resistor 2 (4), and a light emitting tube (3).

[0017] The control port 1 (1) controls the working power of the luminous tube, and is used to control the lighting and extinguishing of the luminous tube. The control port 2 (5) is used to control the high or low brightness of the luminous tube. The control resistor 1 (2) is a low-resistance resistor, which is used to control the brightness of the luminous tube. The control resistor 2 (4) is a high-resistance resistor, which is used to control the low brightness o...

Abstract

The invention discloses an electronic water meter, which comprises a first control port (1), a second control port (5), a first control resistor (2), a second control resistor (4) and a luminotron (3). The beneficial effects of the present invention are that: the highlights, the low light, and the extinguishment of the luminotron is controlled by utilizing two control ports and the like; by matching different scintillation frequencies, a plurality of different operating states are indicated by the luminotron.

Description

technical field [0001] The invention relates to an electronic water meter and belongs to the technical field of luminescent tubes. Background technique [0002] Using light-emitting tubes to indicate the working status of equipment is one of the most commonly used status indication methods. It has the advantages of small footprint, concise and intuitive, and eye-catching. [0003] The light emitting principle of the luminous tube is to convert electrical energy into light energy. The higher the luminous brightness, the more electric energy is consumed. For electronic water meter products, battery power is used, which has very strict restrictions on power consumption, so the conventional light-emitting indication method cannot meet the long-term work requirements of electronic water meters. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an electronic water meter. [0005] The present invention is achieved throu...
